Mt Greenock is an extinct volcano with lava flows associated with a deep lead. It is a tall scoria cone with a broad shallow crater open to the northwest. In the crater are blocks and bombs of scoriaceous basalt. Long lava flows extend both north and south from the cone. It is considered a significant geological site, and part of the Major Mitchell Trail, with a 1936 ‘Centenary of Major Mitchell ‘monument on the summit. The flow to the north has been eroded by McCallum Creek which is a lateral stream. On the eastern base of the cone, the stream valley exposes a lava flow and underlying sedimentary rocks. The lava flow and the scoria cone overlie the Greenock lead (a buried valley with auriferous gravels). A line of mine tailing and abandoned mining relics associated with the former Union Mine occur on the margins of the lava flow. Mount Greenock is a 120 hectare ‘Geological Reserve’, is one of the few large scoria cones on public land and contains abundant outcrop and morphological evidence of its volcanic origin.

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. 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.A solid mass, geological specimen in shades of grey and white. Hyalite is a colourless variety of opal. It occurs as globular and botryoidal masses and irregular crusts in volcanic and pegmatite environments where the silica deposits from the gas phase. Basalt is dark in colour, fine-grained igneous rock composed of plagioclase and pyroxene minerals. It is commonly formed as an extrusive rock, such as lava flow. It is one of the most common forms of rock underlying the earth's surface.burke museum, geological specimen, department of mines, geological survey of victoria, basalt, mount macedon, beechworth

Located 20km from Hamilton and around 15 km from Coleraine, the Wannon Falls present a spectacular display of water flowing down the falls into a deep plunge pool below.

‘Ropy lava’ is known for its sculptural and layered qualities. It occurs in specific lava flows that are slow moving and slow cooling, allowing for unique formations to be created out of the motion. Ropy Lava is a flow that has a hardened crust with molten material underneath, the tension between these states is what creates its characteristic form. The brown/red hue of the stone is an indication of age, as it is oxidised iron deposits. This rock deposit is thought to be sourced from the area by Talbot, in western Victoria. This area has a rich mineral history and experienced the gold rush in the 1850's. The traditional owners of this area are the Dja Dja Wurrung people.This geological specimen shows the conditions in which the Australian landscape was created as well as provides an indication as to how these events occurred. It is representative of a common natural process that contextualises the formation of Australia with the formation of other landmasses.

Although it is not known where these specimens were collected, 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. Agate occurs when amygdales (gas pockets) form in the upper levels of basaltic lava flows. If these pockets or bubbles are iniltrated by water bearing silica in solution, the fluid dries and hardens in layers, forming round or egg shaped nodules or geodes within the rocky matrix. Agate is formed of a silica mineral chalcedony similar to quartz. The term carnelian primarily refers to the reddish shading of the stone; whether the stone is termed an agate or chalcedony type is often influenced by the degree of colour banding the specimen shows. The specimens are significant as examples 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.Three small geological specimens that appear visually consistent with images of rough or unpolished Carnelian Agate or Chalcedony. geological specimen, geology, geology collection, burke museum, beechworth, indigo shire, north-east victoria, gemstones, agate, carnelian

Red Rock, Alvie, near Colac, is a complex of approximately 30 volcanic eruption points and is the Southern most of a chain of three volcanoes, the others being Warrion Hill and Alvie Hill. It is arguably the youngest eruption point in Victoria at around 8000 years, especially since the age of Mt Napier has been progressively pushed back. The highest point (on the Northern side) has many interesting features, including some awesome spatter ramparts. Driving around the rim to the south, you can also see layered tuff. There are some good views out to Lake Corangamite and the lava flows (probably from Warrion Hill) can be seen where they have entered the lake. Most of Red Rock is in private land, with two lookout points with some interpretive information. The water depicted in this photograph is not evident in 2019.

Agate occurs when amygdales (gas pockets) form in the upper levels of basaltic lava flows. If these pockets or bubbles are iniltrated by water bearing silica in solution, the fluid dries and hardens in layers, forming round or egg shaped nodules or geodes within the rocky matrix. Agate is formed of a silica mineral chalcedony similar to quartz. Although relatively common and semi-precious, agate has been prized since at least 1450 BC - an intricately carved agate seal was found in the 2015 excavation of a grave belonging to a Mycenaeum priest or warrior near Pylos in Greece. Agate is also used in jewellery and other decorative or ritual purposes due to its often striking appearance. These specimens originated in North Queensland, which contains noted agate-fossicking regions such as in the area surrounding Forsayth. They were collected in approximately 1852 as an adjunct to the Geological Survey of Victoria. It was donated to the Museum in 1868.

It is formed in deep-seated igneous rocks and crystallized through hot aqueous solutions. It can have two forms; Microcrystalline quartz or Crystalline quartz. Microcrystalline quartz is a fine grain quartz where crystalline quartz is often a large crystal. The colour of quartz can vary. These specimens were collected in Victoria in the vicinity of the Burke Museum.

This particular geological specimen was found in Mount Franklin or Lalgambook in Djadjawurrung, located between Daylesford and Newstead, approximately ninety minutes drive from Melbourne. The mountain is an example of a breached scoria cone (a steep conical hill of loose pyroclastic fragments) which was created by a volcanic eruption about 470,000 years ago, a date which may indicate the age of this geological specimen. The volcanic eruptions of Mount Franklin were most likely witnessed by members of the Dja Dja Wurrung Aboriginal tribe, who referred to this country as the 'smoking grounds'. Mount Franklin and the surrounding area appears to have been a place of considerable religious significance to Aboriginal people, there is evidence which indicates that frequent large ceremonial gatherings took place in the area. Basalt is the most common rock on Earth’s surface, more than 90% of all volcanic rock on Earth is basalt. Basalt is an aphanitic extrusive igneous rock formed from the rapid cooling of low-viscosity lava exposed at or very near the surface of a rocky planet or moon. Specimens are black in colour and weather to dark green or brown. Basalt is rich in iron and magnesium and is mainly composed of olivine, pyroxene, and plagioclase. Olivine is the name of a group of rock-forming silicate minerals with compositions ranging between Mg2SiO4 and Fe2SiO4. Unlike other minerals, Olivine has a very high crystallisation temperature which makes it the first of the minerals to crystallise from magma. As magma cools, the crystals begin to form and settle on the bottom of the lava and form basalts that are abnormally enriched in olivine in the lower part of lava flows. According to H. M. King (on geology.com) "Olivine is thought to be an important mineral in Earth's mantle. Its presence as a mantle mineral has been inferred by a change in the behaviour of seismic waves as they cross the boundary between Earth's crust and mantle". Lava from Mount Franklin and other volcanoes in the area filled valleys and buried the gold bearing streams that became the renowned ‘deep leads’ of the gold mining era. In 1852, as part of the Victorian gold rush, gold was discovered in the immediate area, this gold was created by lava flows during the Newer Volcanic period, which were mined intensively during the nineteenth century. Around 1865 the presence of a deep lead in Mount Franklin was established. Deep lead mining was initially unsuccessful, and it was not until the late 1870s that the Franklinford Gold Mining Company mined at Mount Franklin on a significant scale. A few years later the Mount Franklin Estate Gold Mining Company also struck gold, followed by the Shakespeare and Great Western companies in the mid-1880s. By the late 1880s, however, deep lead mining had ceased in the area. Soon after gold was discovered in 1851, Victoria’s Governor La Trobe wrote to the Colonial Office in London, urging ‘the propriety of selecting and appointing as Mineral Surveyor for this Colony a gentleman possessed of the requisite qualifications and acquaintance with geological science and phenomena’. Alfred Selwyn was appointed geological surveyor in Australia in 1852 which began the Geological Survey of Victoria. In 1853-69 the Geological Survey issued under Selwyn's direction sixty-one geological maps and numerous reports; they were of such high standard that a writer in the Quarterly Journal of the Geological Society of London bracketed the survey with that of the United States of America as the best in the world. During his years spent in Australia, Selwyn collected numerous significant geological specimens, examples of which are held in collections such as the Burke Museum.This geological specimen is an example of basalt and olivine which shows the volcanic lava activity and geographical specific nature of Mt Franklin as a significant volcanic site. According to Agriculture Victoria 'The crater is one of the deepest in the Central Highlands area. It is a major megacryst site with some of the largest known Victorian examples of megacrysts of augite and an orthoclase. The small parasitic mound of Lady Franklin on the western flanks adds to the geological interest of the site'. This specimen also highlights the locality as a significant place for both indigenous activity and Victorian gold rush era mining practices. 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.

Thunderegg Agates are formed within rhyolite volcanic ash layers. They are rough spherical shapes, varying in size from less than an inch to over a metre long. Thundereggs usually contain centres of chalcedony which may have been fractured followed by deposition of agate, jasper or opal, either uniquely or in combination. A unique characteristic that these specimens have is the fact that they often look like ordinary rocks on the outside, but slicing them in half and polishing them may reveal intricate patterns and colours. These particular specimens are examples of thunderegg agates. Agate is a variety of chalcedony, a cryptocrystalline form of quartz. The agate component contributes to the intriguing internal patterns of the specimens. The specific locality of these specimens is unknown but they can be found in flows of rhyolite lava. They are formed in gas pockets in the lava, which act as moulds. These specimens can be found globally, with specific locations in Germany being particularly abundant. 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.
