Native Sulphur in its solid form is a yellow crystalline mineral that forms near volcanic vents and fumaroles where it is the solid form of hot gases. It is also frequently found in the subsurface as a by-product of sulphide ore mineralization. In all its forms, sulphur is one of the most commonly occurring minerals on the planet, especially in natural gases, and is key to the make-up of a range of other minerals. It is essential to continuing life on earth, and was used in ancient societies as part of medical care, religious rites, and entertainment, and was key to the invention of gunpowder by the Chinese.

The exact site of extraction for this specimen is unknown, but it was probably collected in New Zealand in the 1850s. Sulphur is significant both for its historical and current uses, and for its nature as one of the most abundant minerals on the planet. Sulphur's importance comes both from its abundance and its role in ensuring survival, creating other minerals, and daily human life. This specimen is significant as representative of sulphur's solid properties. 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, small, crystalline mineral specimen that is largely bright yellow, with some darker spotting. geological specimen, geology, geology collection, burke museum, beechworth, sulphur, native sulphur, new zealand, native sulphur specimen, sulphur specimen

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.

A fossil refers to any remains or traces of past life that are preserved in the rock. It could be remains of plants or animals. Fossil leaves are commonly found on different types of rocks. These fossils can go as far back as the Triassic Age just like the series of fossil plants collected at Denmark Hill, Ipswich in Queensland. Fossils leaves are formed when dead plants get buried by sediments like mud, sand, or volcanic ash. Often, it gets detached cleanly from stems along a special layer of weak cells, then twigs, and, less commonly, cones of conifers and fruits and seeds of flowering plants. Over time, the leaves or pieces of leaves get buried by more sediments and eventually gets 'lithified' or hardened into a rock. Erosions and mining can cause the rocks to break and reveal the fossils buried in it. Fossilisation frequently takes place at sites in the lowlands where deposits of clay, silt, sand are found. This is usually due to weathering and erosion of rocks. Fossil leaves can provide information about ancient Australia's way of living. It contributes to Victorian biodiversity records and its botanical collections. It also contributes information on the geographical profile of Victoria as fossilisation usually occur at estuaries and deltas of rivers, river flood plains, ponds and lakes.

Ventifacts are sand-blasted rocks that are typically faceted and often display parallel grooves carved by wind-blown sand. They are useful indicators of wind direction and strength in environments such as deserts, mountains, and coastal areas because they are usually not hidden by later sediment, soil or vegetation cover. In Antarctica ventifaction is strongly related to the composition or type of rock. Ventifacts are important because they provide evidence for abraders such as sand, dust or snow and ice crystals, and offer a unique understanding of past wind processes that are effective in the reconstruction of past wind flow conditions and can provides clues to weather and climate changes in the past. Interestingly ventifacts have also been found on the surface of Mars. They were a threat to the NASA rover due to the sharp angles of the facets, created by the Martian wind over the course of millions of years. These Martian ventifacts act like weathervanes for past wind and weather patterns on the red planet in a similar manner to those found on earth.The Geological Survey of Victoria was instigated in response to the Victorian Gold Rush which began around 1851 in the Beechworth, Castlemaine, Daylesford, Bendigo and Ballarat areas. The survey was conducted by Alfred Richard Cecil Selwyn from his arrival in December 1852 until his resignation in 1869and during this time he trained many notable geologists, e.g. Aplin, Wilkinson, Daintree, who went on to other State survey senior positions.

Galena is the natural compound of lead and classed as a sulphide, it crystallises in a cubic pattern and its chemical formula is PbS. Galena is a primary source of both lead and silver. This specimen of Galena comes from Broken Hill. Broken Hill has one of the world’s largest and most significant deposit of ore for the production of lead. Mining of Galena at Broken Hill began with the staking of land by Charles Rasp in 1883. By the following year, in 1884, Rasp and six others had formed Broken Hill Mining Company. Broken Hill Mining Company eventually evolved into BHP group limited and is currently the largest mining company in the world and the largest company in Australia. There is archaeological evidence from artefacts discovered in Turkey that humans have been extracting lead from galena by the process of smelting since at least 6500 BCE. This specimen also has quartz on the top surface which is frequently discovered alongside Galena. This mineral specimen is of historic significance as a sample of Galena extracted from Broken Hill during the 19th century. Mining for Galena in Broken Hill begin in 1883 by Charles Rasp and evolved into the world’s largest mining company – BHP Group Limited. Broken Hill is one of the world’s most significant deposits of ore for the production of lead.

Sphalerite or sphaelerite is named from the Greek word for 'treacherous' or 'deceiver' as specimens can vary widely in appearance, making them hard to visually identify. It is a zinc sulfide with the chemical composition (Zn,Fe)S, the most important ore of zinc. Specimens of sphalerite can contain iron as a substitute for up to 25% of the usual zinc present, as well as trace elements of gallium, cadmium, geranium and indium. Small amounts of arsenic and manganese may also be detected. Sphalerite is found in igneous, sedimentary and metamorphic rocks. It forms when carbonate rock encounters acidic, zinc-bearing fluid. It often forms in veins or in fissures of the existing rock, with colours and crystal shapes dependent on the composition of the the combining elements. It forms isometric crystal shapes including cubes, tetrahedrons, octahedrons, dodecahedrons. This specimen was collected in approximately 1852, in Broken Hill, NSW, as an adjunct to 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.The specimen is significant as an 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.A pipe-shaped specimen of sulfide-mineral zinc ore displaying patches of black, brown, beige and gold colouring.

The Australian magpie is a passerine native to Australia and southern New Guinea. Renowned for its black and white plumage and distinctive song, the Australian magpie has also established populations in New Zealand and on the Fijian island of Taveuni, where it was introduced during the 19th century. Previously classified as three distinct species, it is now recognized as a single species comprising nine subspecies. Belonging to the family Artamidae, the Australian magpie is the sole member of the genus Gymnorhina and shares its closest relation with the black butcherbird (Melloria quoyi). Unlike the Eurasian magpie, it is not part of the Corvidae family. This specimen is part of a collection of almost 200 animal specimens that were originally acquired as skins from various institutions across Australia, including the Australian Museum in Sydney and the National Museum of Victoria (known as Museums Victoria since 1983), as well as individuals such as amateur anthropologist Reynell Eveleigh Johns between 1860-1880. These skins were then mounted by members of the Burke Museum Committee and put-on display in the formal space of the Museum’s original exhibition hall where they continue to be on display. This display of taxidermy mounts initially served to instruct visitors to the Burke Museum of the natural world around them, today it serves as an insight into the collecting habits of the 19th century. This specimen is part of a significant and rare taxidermy mount collection in the Burke Museum. This collection is scientifically and culturally important for reminding us of how science continues to shape our understanding of the modern world. They demonstrate a capacity to hold evidence of how Australia’s fauna history existed in the past and are potentially important for future environmental research. This collection continues to be on display in the Museum and has become a key part to interpreting the collecting habits of the 19th century.This specimen an Australian Magpie with black and white plumage over the body, mounted on a cedar stand. The specimen has a large straight beak and is in an unusual pose for a magpie, compressing the white patch on the back of the neck.

The family Chelidae is endemic to Australia, New Guinea, and South America and consists of some 40 species of freshwater turtle. Twenty-four described species are found in Australia and three of these occur in the Murray Darling Basin. Turtles of the genus Chelodina are distinguished by their exceptionally long necks. These turles are also referred to as side-necked turtles, so named because the neck and head, when not extended, fold under the leading edge of the carapace. They are further characterised by their relatively flattened shells and their clawed webbed feet. This specimen is part of a collection of almost 200 animal specimens that were originally acquired as skins from various institutions across Australia, including the Australian Museum in Sydney and the National Museum of Victoria (known as Museums Victoria since 1983), as well as individuals such as amateur anthropologist Reynell Eveleigh Johns between 1860-1880.
