Geological specimen - Cerussite, Unknown c.1890s
Named in 1845 by Wilhelm Karl von Haidinger cerussite takes its name from the Latin cerussa, meaning 'white lead'. When viewed under certain lighting conditions cerussite gives of fire and rainbow-like colours (due to its high dispersion) and it is quite sought after by geological collectors for this very reason. Cerussite is usually found in the oxidised zone of lead ore deposits. It is a very common weathering product of galena and other lead ore minerals. It is a secondary mineral, meaning it forms as a result of the alteration of pre-existing minerals in the Earth’s crust. The presence of lead in cerussite makes it potentially toxic. Historically, it has been an important source of lead, which has numerous industrial applications, including in batteries, construction materials, and radiation shielding. Cerussite has a crystal structure that belongs to the orthorhombic crystal system. Its crystal structure is characterized by a three-dimensional arrangement of atoms in a repeating pattern. The crystal lattice of cerussite consists of interconnected lead (Pb) and carbonate (CO3) ions. This crystal structure is visible in the specimen. This specimen was found in Dundas (formerly Mount Dundas), a historical mining locality, mineral field and railway located on the western foothills of the West Coast Range in Western Tasmania. During the 1890s Dundas swelled in numbers however it is now lost in a temperate rainforest and its population is now 2. The present Dundas Extended mine, about 1.5 km east of Dundas is presently worked for specimen material.Faceted cerussite gems are considered rare and valuable, given the softness of the mineral. This item is not a faceted gem however its historical and scientific research potential give it significance; mined in an Australian township, this cerussite could shed light on the now lost history of Dundas and the mining that occurred there. Additionally, the uses of this mineral in historical industrial processes give it scientific significance. Such knowledge can add to understandings of the geographical and geological nature of Western Tasmania and allow for further study of Australian geological specimens.

Geological specimen - Native (metallic) copper, Unknown
This specimen is a native copper specimen that is metallic. Copper is typically found in the earth's crust and is often found alongside other metals such as gold, zinc, lead and silver which all belong to the same group which is the Copper/Gold group. Copper is most commonly formed from large masses of molten lava rock which has solidified in the earth's crust and over time though different sizes and speeds of crystal growth has turned into large amounts of copper, stored in porphyry copper deposits. Copper has a distinctive colour, yet can sometime appear blue and greenish which is often caused by oxidisation or a mixture of copper and other metals. This specific specimen was recovered from Moonta, South Australia. The Moonta Mining Company was established in 1861, after a Shepard in the area noticed traces of copper. This lead to a rush in the copper mining industry which was relatively young in Australia at the time, making Moonta Mining Company one of the richest in Australia. By the 1860's, South Australia had been nicknamed the "Copper Kingdom" due to its vast amount of Large copper mines and resources. As of 2016, Australia was the second largest producer of Copper internationally, following behind Chile in first place. This copper specimen is significant historically and scientifically as it is such an important metal commonly used throughout the world in various ways. Copper is an invaluable recourse used in daily life, used in most electrical appliances as it is a great conductor of heat and electricity, as well as being soft and malleable, making it easy to bend and mould into delicate sheets and wires. Copper does not corrode and is therefore used in the production of water pipes among countless other significant necessities that are often overlooked in our society. Historically, Copper holds great significance as it was the first metal used by humans. It was discovered roughly 9000 years ago and was utilised by the Neolithic Man who learnt that heating the metal made it more malleable, thus tools and utensils were made which were far superior to the previous stone tools used by humans. This history and its connection to the current and ongoing relationship between humans and copper must be preserved and highlighted as it is integral to the history of all humankind.

Geological specimen - Kaolin, unknown
Kaolin is also known as china clay. This specimen came from Dunolly, Victoria and was donated to the Museum in 1868 as part of the Geological Survey of Victoria. This survey helped map and study the geology of Victoria. In Victoria, Kaolin is particularly used as a filler and coating material in paper manufacture. It can also be used in paints, ceramics, rubbers and plastics. There are many kaolin deposits in Victoria but many of these have been mined out and there is not much Kaolin left. Rocks that have a high amount of Kaolinite and it can be formed through the decomposition of other materials. There are two types of Kaolin; hard and soft kaolin. Soft kaolin's are coarse but have a soapy texture. It can also break easily. The hard kaolins have an earthly texture and are finer grained. This means that they are harder to break, unlike the soft kaolin. Hard kaolin's are formed by flocculation in salt water, a process that in basic terms, bonds particles together. Kaolin is a common material in Victoria and that is why it is significant. While this specimen was mined in Dunolly, Victoria Kaolin can also be found Pittong, Pakenham, Bulla, Hallam and Ballarat as well as many other places throughout Victoria. This specimen represents the presence of Kaolin deposits in this region of Australia. It is also significant because Kaolin has many uses and is largely beneficial to many manufacturing processes in Victoria. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria. Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study.Two pieces of Kaolinite mineral with shades of white and graygeological specimen, geology, geology collection, burke museum, beechworth, kaolin, china clay, dunolly, geological survey of victoria, kaolinite, victoria, mining, mining deposits, geology of victoria, australia, filler, coating material, paper manufacture, paint, ceramics, rubbers, plastics, decomposition, materials, soft kaolin, hard kaolin, flocculation, particles, salt water -

Geological specimen - Laterite
Laterite refers to both a rock and a soil type that is rich in clay, as well as Iron and Aluminium. It is created during a process that is called laterization, where high heat and seasonal heavy rainfall cause there to be wet and dry periods, which over time hardens the soil into rock. Because of this, most laterite is formed between tropics of Cancer and Capricorn. The iron oxide in laterite is what gives it it’s orange-red colouring. The largest religious complex in the world, Angkor Wat in Cambodia, is partially constructed of laterite, particularly its foundations, as laterite is porous and allows rainwater to drain. This specimen of laterite was collected from the Democratic Republic of Congo while it was colonised by Belgium in the 19th century. Laterite forms in many parts of the world, particularly between the tropics. It is used both for ore and as a building material, and comparing specimens from different parts of the world allows us to document the different compositions that this mineral can have when formed at different locations. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria.

Geological specimen - Rhodonite with Galena and Sphalerite
This specimen is from Broken Hill, NSW. Galena is a natural mineral form of lead sulphide and is often found associated with sphalerite, calcite, and fluorite. Galena is an important lead ore mineral, and, in some regions, it is also an important mineral associated with silver ore. Sphalerite is a sulphide mineral that is the main ore of zinc. Rhodonite is an uncommon mineral once used as an ore of manganese in India, however today the scarcity and fragility of the crystals mean it is primarily used as lapidary materials or mineral specimens. In 1883, Charles Rasp who was a boundary rider at the time, discovered what he thought were deposits of tin but were in fact samples of silver and lead. He and six others went on to set up the first mining company in Broken Hill (BHP). The ore body became the largest and richest of its kind in the world mining ore worth more than 42,000 pounds in its first year. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study. Galena contains lead and silver, Sphalerite contains zinc. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Geological specimen - Actionlite and Pyrite
Actinolite is usually found in metamorphic rocks, such as contact aureoles surrounding cooled intrusive igneous rocks. It also occurs as a product of the metamorphism of magnesium-rich limestones. Pyrite is usually found with other sulfides or oxides in quartz veins, sedimentary rock, and metamorphic rock, as well coal beds, and as a replacement mineral in fossils. Actinolite is an amphibole silicate mineral. It is named after the Greek word "aktinos" meaning “ray” in allusion to the mineral's fibrous nature. Fibrous actinolite is a type of asbestos and was once mined along Jones Creek at Gundagai, New South Wales. Pyrite or "Fool's Gold" is the most common sulfide mineral. It is named after the Greek "pyr" meaning "fire" because it can be used to create sparks needed for a fire if struck against metal or a hard surface. Due to its gold colour, pyrite can be mistaken for gold and often forms alongside it, causing small amounts of gold to be present in rocks containing pyrite. Most importantly, pyrite is an ore of gold. Pyrite is sometimes used as a gemstone but is not great for jewellery as it easily tarnishes. In some fossils of ammonites – shelled cephalopods that died ~66 million years ago – pyrite also replaces the shell. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria.

Geological specimen - Montmorillonite
Montmorillonite is a type of clay composed of aluminium silicate that forms very small particles that are not well-bonded to one another. This is why it is so soft. When in the presence of water, all types of clay swell. Montmorillonite swells even more than most types of clay, which is why it is often chosen over other types of clay in its practical uses. Montmorillonite has many different practical uses, including in the mining industry, as a soil additive, as a sealant, as a desiccant to draw water out of the air, to clean ponds, to make kitty litter and in cosmetics. Montmorillonite is a common mineral and, despite being named after Montmorillon, France, can be found all over the world, including many deposits in Australia. It is not known where this particular specimen originates from. Montmorillonite is an economically and socially significant material with a wide variety of uses. Having samples of common and important minerals allows collections, like the Burke Museum, to have a more complete view of the land on which they are located, and therefore a more complete view of heritage. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Geological specimen - Anthracite crystal, Unknown
Anthracite typically occurs in geologically deformed areas due to extreme heating – with temperatures ranging from 170 to 250 °C – caused by igneous intrusions or high geothermal gradients. It is most commonly found in northeastern Pennsylvania in the United States; however, smaller amounts are also found in Australia, China, eastern Ukraine, South Africa, western Canada, and other countries. This specimen was recovered from Tasmania and is 85-95% carbon.Anthracite is the mineral name for hard coal and is the least plentiful of all coal types. It is clean to the touch and, when polished, is used for decorative purposes. Before natural gas and electricity, anthracite was used for domestic heating as it produces little dust, burns slowly, and gives off a minor amount of smoke. However, it is also limited in abundance and expensive. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Geological specimen - Slate, c. 1908
The iron-hulled, four-masted barque, the Falls of Halladale, was a bulk carrier of general cargo. She left New York in August 1908 on her way to Melbourne and Sydney. In her hold, along with 56,763 tiles of unusual beautiful green American slates (roof tiles), 5,673 coils of barbed wire, 600 stoves, 500 sewing machines, 6500 gallons of oil, 14400 gallons of benzene, and many other manufactured items, were 117 cases of crockery and glassware. Three months later and close to her destination, a navigational error caused the Falls of Halladale to be wrecked on a reef off the Peterborough headland at 3 am on the morning of the 15th of November, 1908. The captain and 29 crew members all survived, but her valuable cargo was largely lost, despite two salvage attempts in 1908-09 and 1910. ABOUT THE ‘FALLS OF HALLADALE’ (1886 - 1908) Built: in1886 by Russell & Co., Greenock shipyards, River Clyde, Scotland, UK. The company was founded in 1870 (or 1873) as a partnership between Joseph Russell (1834-1917), Anderson Rodger and William Todd Lithgow. During the period 1882-92 Russell & Co., standardised designs, which sped up their building process so much that they were able to build 271 ships over that time. In 1886 they introduced a 3000 ton class of sailing vessel with auxiliary engines and brace halyard winches. In 1890 they broke the world output record. Owner: Falls Line, Wright, Breakenridge & Co, 111 Union Street, Glasgow, Scotland. Configuration: Four masted sailing ship; iron-hulled barque; iron masts, wire rigging, fore & aft lifting bridges. Size: Length 83.87m x Breadth 12.6m x Depth 7.23m, Gross tonnage 2085 ton Wrecked: the night of 14th November 1908, Curdies Inlet, Peterborough south west Victoria Crew: 29 The Falls of Halladale was a four-masted sailing ship built-in 1886 in Glasgow, Scotland, for the long-distance cargo trade and was mostly used for Pacific grain trade. She was owned by Wright, Breakenridge & Co of Glasgow and was one of several Falls Line ships, all of which were named after waterfalls in Scotland. The lines flag was of red, blue and white vertical stripes. The Falls of Halladale had a sturdy construction built to carry maximum cargo and able to maintain full sail in heavy gales, one of the last of the ‘windjammers’ that sailed the Trade Route. She and her sister ship, the Falls of Garry, were the first ships in the world to include fore and aft lifting bridges. Previous to this, heavily loaded vessels could have heavy seas break along the full length of the deck, causing serious injury or even death to those on deck. The new, raised catwalk-type decking allowed the crew to move above the deck stormy conditions. This idea is still used today on the most modern tankers and cargo vessels and has proved to be an important step forward in the safety of men at sea. On 4th August 1908, with new sails, 29 crew, and 2800 tons of cargo, the Falls of Halladale left New York, bound for Melbourne and Sydney via the Cape of Good Hope. The cargo on board was valued at £35,000 and included 56,763 tiles of American slate roof tiles (roof slates), 5,673 coils of barbed wire, 600 stoves, 500 sewing machines, 6,500 gallons of oil, 14,400 gallons of benzene, plumbing iron, 117 cases of crockery and glassware and many other manufactured items. The Falls of Halladale had been at sail for 102 days when, at 3 am on the night of 14th November 1908, under full sail in calm seas with a six knots breeze behind and misleading fog along the coast, the great vessel rose upon an ocean swell and settled on top of a submerged reef near Peterborough on the south-west Victoria’s coast. The ship was jammed on the rocks and began filling with water. The crew launched the two lifeboats and all 29 crew landed safely on the beach over 4 miles away at the Bay of Islands. The postmistress at Peterborough, who kept a watch for vessels in distress, saw the stranding and sent out an alert to the local people. A rescue party went to the aid of the sailors and the Port Campbell rocket crew was dispatched, but the crew had all managed to reach shore safely by the time help arrived. The ship stayed in full sail on the rocky shelf for nearly two months, attracting hundreds of sightseers who watched her slowly disintegrate until the pounding seas and dynamiting by salvagers finally broke her back, and her remains disappeared back into deeper water. The valuable cargo was largely lost, despite two salvage attempts in 1908-09 and 1910. Further salvage operations were made from 1974-1986, during which time 22,000 slate tiles were recovered with the help of 14 oil drums to float them, plus personal artefacts, ship fittings, reams of paper and other items. The Court of Marine Inquiry in Melbourne ruled that the foundering of the ship was entirely due to Captain David Wood Thomson’s navigational error, not too technical failure of the Clyde-built ship. The shipwreck is a popular site for divers, about 300m offshore and in 3 – 15m of water. Some of the original cargo can be seen at the site, including pieces of roof slate and coils of barbed wire The Falls of Halladale shipwreck is listed on the Victorian Heritage Register (No. S255). She was one of the last ships to sail the Trade Routes. She is one of the first vessels to have fore and aft lifting bridges. She is an example of the remains of an International Cargo Ship and also represents aspects of Victoria’s shipping industry. The wreck is protected as a Historic Shipwreck under the Commonwealth Historic Shipwrecks Act (1976).Californian, American, rectangular blue roof slate tile, recovered from the wreck of the Falls of Halladale. flagstaff hill, warrnambool, shipwrecked-coast, flagstaff-hill, flagstaff-hill-maritime-museum, maritime-museum, shipwreck-coast, flagstaff-hill-maritime-village, falls of halladale., slate, roof slate, russell & co. -

Geological specimen - Common Opal, unknown
Common Opal is a mineraloid that is non crystallising and is classed as an amorphous silicate, the chemical composition for Opal is SiO2 nH2O. Opals can develop in weathered sedimentary rock typical in arid regions where limited water enters small gaps in the rock, and the silicate is hydrated. Common opals, unlike precious opals, do not exhibit ‘play of colour’ in which the colour appears to change depending on the angle of view. While precious opals are highly valuable and cut as gemstones for jewellery, common opals can be cut into inexpensive gemstones and are also mined for various uses including as ingredients in ceramics, insulation, fillers, and abrasives. The source of this common opal specimen is unknown, but common opals are found around the world, notable deposits are found in Queensland, South Australia, New South Wales, Peru, Kenya, Nevada, Oregon, and Mexico. This common opal specimen is of historic and scientific significance due to its donation in 1868 as part of the Geological Survey of Victoria and as a typical example of uncut common opal. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Geological specimen - Opal Bearing Stone, Unknown
There are 17 opal fields in Australia. This opal bearing stone was found in Lightning Ridge, NSW over what is known as the Great Australian Basin. This basin was formed and covers an area of 1.7 million square kilometers in eastern Australia in the Cretaceous period. This basin used to contain an inland sea, which provided an environment where silcrete eventually formed when water levels changed. This eventually seeped into other structures, and eventually hardened and formed opal. Lightning Ridge has a population of around 2000 people, with about 80 000 visitors every year. It is a historic mining town, and is known for its deposits of a rare black opal. Mining started in the area in the late 1800s, early 1900s when the black opal was discovered. This opal-bearing stone is of social and historical significance. It is from Lightning Ridge, which is well-known for being a large producer of opal stones, most famously black opal. The history of the period dates back to 140 million years, with the discovery of black opal in the early 1900s causing interest in the area.

Geological specimen - Loellingite in Rhodonite
Rhodonite is a reddish-pink manganese silicate material and often contains iron, magnesium and calcium. It is usually found in metamorphic rocks (rocks which have been altered by heat, pressure or chemical process). It can range in size from tiny to massive. Because of their composition they are not suitable for use in jewellery because they are hard enough. It is quite rare to find, though has been found in Australia, North America, South America and Europe.This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Geological specimen - Sample of Pulverised Dried Brown Coal, Maddingley Brown Coal Mine, 1981
The Maddingley area of Bacchus Marsh was surveyed for brown coal deposits in the 1930s. By the early 1940s brown coal in large quantities was being extracted and was transported to Melbourne where it was used to fire boilers for the Australian Paper Mills (APM) company. By the 1970s APM was using natural gas instead of coal. Maddingley brown coal was then used to fire boilers for the CRA/VISY cardboard factory at Bacchus Marsh. This factory closed down in 1990. During the 1990s the mine was acquired by the Calleja family company who ran transport and waste management operations.The Maddingley Brown coal mine was a major industry in Bacchus Marsh for 50 years. A sample of coal from the mine is a reminder of the importance of this local industry over an extended period of time.Two cylindrical plastic containers mounted on rectangular baseSample of pulverised brown coal produced from Maddingley brown coal deposit located at Bacchus Marsh Victoria, October 1981.

Geological specimen - Selwynite, Unknown
Selwynite is a fine-grained, compact green rock made primarily of chromian muscovite (fuchsite) and diaspore. Corundum and fuchsite can occur together in the form of massive aggregates or nodules. Often, copper carbonates are found as earthy films or tiny crystals in joint planes. The mineral name honours the late A. R. C. Selwyn, founding Director of the Geological Survey of Victoria. The particular specimen, a mottled green stone suitable for carving was recovered and found in Heathcote, Victoria, Australia. The rarity and qualities of this mineral attracted commercial mining, which was not successful, but traces of the mine shafts still exist today, and it is still highly valued by mineral collectors.Selwynit is considered to be one of the rare forms of rock because it is composed of phosphate minerals containing zirconium. This is an extremely rare combination found in nature. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Geological specimen - Hyalite in Basalt
According to the 1912 Department of Mines Bulletin of the Geological Survey of Victoria, basalt covers a considerable portion of the Macedon area including Mount Macedon. Basalt is the most common form of rock underlying the earth's surface and is found in three kinds of rock forming environments: ocean divergent boundaries, oceanic hotspots, and mantle plumes and hotspots beneath continents.This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Geological specimen - Slate
The iron-hulled, four-masted barque, the Falls of Halladale, was a bulk carrier of general cargo. She left New York in August 1908 on her way to Melbourne and Sydney. In her hold, along with 56,763 tiles of unusual beautiful green American slates (roof tiles), 5,673 coils of barbed wire, 600 stoves, 500 sewing machines, 6500 gallons of oil, 14400 gallons of benzene, and many other manufactured items, were 117 cases of crockery and glassware. Three months later and close to her destination, a navigational error caused the Falls of Halladale to be wrecked on a reef off the Peterborough headland at 3 am on the morning of the 15th of November, 1908. The captain and 29 crew members all survived, but her valuable cargo was largely lost, despite two salvage attempts in 1908-09 and 1910. ABOUT THE ‘FALLS OF HALLADALE’ (1886 - 1908) Built: in1886 by Russell & Co., Greenock shipyards, River Clyde, Scotland, UK. The company was founded in 1870 (or 1873) as a partnership between Joseph Russell (1834-1917), Anderson Rodger and William Todd Lithgow. During the period 1882-92 Russell & Co., standardised designs, which sped up their building process so much that they were able to build 271 ships over that time. In 1886 they introduced a 3000 ton class of sailing vessel with auxiliary engines and brace halyard winches. In 1890 they broke the world output record. Owner: Falls Line, Wright, Breakenridge & Co, 111 Union Street, Glasgow, Scotland. Configuration: Four masted sailing ship; iron-hulled barque; iron masts, wire rigging, fore & aft lifting bridges. Size: Length 83.87m x Breadth 12.6m x Depth 7.23m, Gross tonnage 2085 ton Wrecked: the night of 14th November 1908, Curdies Inlet, Peterborough south west Victoria Crew: 29 The Falls of Halladale was a four-masted sailing ship built-in 1886 in Glasgow, Scotland, for the long-distance cargo trade and was mostly used for Pacific grain trade. She was owned by Wright, Breakenridge & Co of Glasgow and was one of several Falls Line ships, all of which were named after waterfalls in Scotland. The lines flag was of red, blue and white vertical stripes. The Falls of Halladale had a sturdy construction built to carry maximum cargo and able to maintain full sail in heavy gales, one of the last of the ‘windjammers’ that sailed the Trade Route. She and her sister ship, the Falls of Garry, were the first ships in the world to include fore and aft lifting bridges. Previous to this, heavily loaded vessels could have heavy seas break along the full length of the deck, causing serious injury or even death to those on deck. The new, raised catwalk-type decking allowed the crew to move above the deck stormy conditions. This idea is still used today on the most modern tankers and cargo vessels and has proved to be an important step forward in the safety of men at sea. On 4th August 1908, with new sails, 29 crew, and 2800 tons of cargo, the Falls of Halladale left New York, bound for Melbourne and Sydney via the Cape of Good Hope. The cargo on board was valued at £35,000 and included 56,763 tiles of American slate roof tiles (roof slates), 5,673 coils of barbed wire, 600 stoves, 500 sewing machines, 6,500 gallons of oil, 14,400 gallons of benzene, plumbing iron, 117 cases of crockery and glassware and many other manufactured items. The Falls of Halladale had been at sail for 102 days when, at 3 am on the night of 14th November 1908, under full sail in calm seas with a six knots breeze behind and misleading fog along the coast, the great vessel rose upon an ocean swell and settled on top of a submerged reef near Peterborough on the south-west Victoria’s coast. The ship was jammed on the rocks and began filling with water. The crew launched the two lifeboats and all 29 crew landed safely on the beach over 4 miles away at the Bay of Islands. The postmistress at Peterborough, who kept a watch for vessels in distress, saw the stranding and sent out an alert to the local people. A rescue party went to the aid of the sailors and the Port Campbell rocket crew was dispatched, but the crew had all managed to reach shore safely by the time help arrived. The ship stayed in full sail on the rocky shelf for nearly two months, attracting hundreds of sightseers who watched her slowly disintegrate until the pounding seas and dynamiting by salvagers finally broke her back, and her remains disappeared back into deeper water. The valuable cargo was largely lost, despite two salvage attempts in 1908-09 and 1910. Further salvage operations were made from 1974-1986, during which time 22,000 slate tiles were recovered with the help of 14 oil drums to float them, plus personal artefacts, ship fittings, reams of paper and other items. The Court of Marine Inquiry in Melbourne ruled that the foundering of the ship was entirely due to Captain David Wood Thomson’s navigational error, not too technical failure of the Clyde-built ship. The shipwreck is a popular site for divers, about 300m offshore and in 3 – 15m of water. Some of the original cargo can be seen at the site, including pieces of roof slate and coils of barbed wire. SIGNIFICANCE The Falls of Halladale shipwreck is listed on the Victorian Heritage Register (No. S255). She was one of the last ships to sail the Trade Routes. She is one of the first vessels to have fore and aft lifting bridges. She is an example of the remains of an International Cargo Ship and also represents aspects of Victoria’s shipping industry. The wreck is protected as a Historic Shipwreck under the Commonwealth Historic Shipwrecks Act (1976).

Geological specimen - Dolomite
Dolomite is a mineral, calcium magnesium carbonate, with the chemical formula CaMg(CO3)2. It is a principle component of various rock types sometimes also referred to as dolomite, including dolostone, dolomitic marble and dolomitic limestone (according to the composition of each type). Dolomite rock is found in sedimentary basins throughout the world, comprising approximately 2% of the Earth's crust. It is formed when lime mud or limestone encounters groundwater containing magnesium. Dolomite can contain elements such as lead, zinc and copper. Dolomite and limestone are used in various construction, landscaping and agricultural processes. This specimen was donated to the Burke Museum in 1868 by Alfred Selwyn as part of the Geological Survey of Victoria. It was donated to the Museum in 1868. Victoria and other regions of Australia were surveyed for sites of potential mineral wealth throughout the 19th Century. The identification of sites containing valuable commodities such as gold, iron ore and gemstones in a locality had the potential to shape the development and history of communities and industries in the area. The discovery of gold in Victoria, for instance, had a significant influence on the development of the area now known as 'the goldfields', including Beechworth; the city of Melbourne and Victoria as a whole. Dolomite and limestone are mined at several locations in Victoria, including sites in the North-East of the state in Bindi and Limestone Creek. There are notable dolomite deposits in most Australian states. The dolomitised form of the mineral tends to come from older limestone deposits, formed during the palaeozoic era in marine settings, so this specimen may have come from a deposit located along a coastline in Victoria or another state. The specimen is significant as an example of surveying activity undertaken to assess and direct the development of the mineral resource industries in Victoria and Australia, as well as the movement to expand human knowledge of earth sciences such as mineralogy and geology in the nineteenth century. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Geological specimen - Olivine Crystals, Unknown
Olivine is mostly found on the Earth's surface in igneous rocks that are dark-coloured. It is common at divergent plate boundaries and at warm spots, such as volcanic areas. It crystalises and forms during the cooling of magma. Olivine is used in refractory sand, bricks, and gemstones. Olivine has been found on a number of meteorites, which might have originated from large asteroids or the mantle of a now-destroyed planet. This olivine crystal is thought to originate from Mount Noorat, with speculation that it could have originated from Mount Shadwell. Mount Noorat is a dormant volcano cone located in the Newer Volcanics Province of Victoria. Mount Noorat belongs to the Kirrae Wuurong people, who used the Mount as a place for meetings and gatherings prior to European settlement. Contact was first made between European settlers and the Indigenous people in 1841. The Mount has mostly been used for cattle and sheep grazing. Mount Shadwell is a well-known source of olivine and is the highest of a gathering of volcanic cones. The New Volcanic Province is located in South East Australia and covers 15000 square kilometres. It contains 400 explosive vents and small shield volcanoes. The last eruption is thought to have occurred 5000 years ago at Mount Gambier and Mount Schank. This olivine crystal has been identified as a volcanic bomb, which is a molten rock which was pushed out and ejected into the air when a volcano reupts. A rock needs to be larger than 65 mm in diameter to be classified as a volcanic bomb. This olivine volcanic bomb and its locality is historically and socially significant. The olivine was found in the Newer Volcanic Province, an area which contains over 400 dormant volcanoes. This olivine is one part of a volcanic bomb, which would have ejected when magma erupted out of a volcano.

Geological specimen - Gold Telluride Ore
Gold usually is found as a native metal, but it also forms minerals with tellurium, sulphur, or selenium. The gold-bearing minerals that contain tellurium are called tellurides. Kalgoorlie, Western Australia contains greater than 1500 tonnes of gold.Seventy to seventy-five percent of the deposit occurs as native gold, but a further twenty percent appears as tellurides. What remains is in the form of 'invisible' gold. Extracting gold from telluride minerals, such as calaverite, which contains around forty-two percent gold, has produced approximately three hundred tonnes of gold. Prior to 1896, rocks containing tellurides were not recognised as rich gold ores, and were discarded.This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Geological specimen - Common Opal, Unknown
It is not known where this opal originated. Common Opal is formed from silica-rich water entering the earths crust and hardening into a gel of water and silica-spheres, layered through the specimen. Common opal differs from precious opal in colouration and appearance, with precious opal including more colours, and having a translucent or glossy appearance, where common opal shows less colour and is typically opaque. It scores high on the Mohs hardness scale, and is common throughout the world, especially in Australia, where it is far more prevalent than the highly-prized precious opal. Australia is also the highest producer of opals in the modern world.
