Geological specimen - Basalt (igneous-volcanic) containing Olivine, unknown
... volcanic rock on Earth is basalt. Basalt is an aphanitic extrusive... volcanic rock on Earth is basalt. Basalt is an aphanitic extrusive ...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. 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.An angular, solid hand-sized piece of grey volcanic Basalt with green/brown Olivine phenocrysts along one flat edge.Olivine in basalt / - label is probably / correct. / C.

He arrived in Adelaide with his parents in about 1860. In 1867, following photographic journeys in Gippsland, he opened a studio in Adelaide. From 1870 to 1876 he lived and worked in Talbot in Central Victoria. In 1876 he purchased T. F. Chuck's studios in the Royal Arcade Melbourne. In 1885, following the introduction of dry plate photography, he began a series of landscape series, which were commercially successful. As a photographer, he travelled extensively through Victoria, photographing places few of his contemporaries had previously seen. He died in 1918. Reference: Jack Cato, 'Caire, Nicholas John (1837–1918)', Australian Dictionary of Biography.An original, rare photograph from the series 'Views of Victoria: General Series' by the photographer, Nicholas Caire (1837-1918). The series of 60 photographs that comprise the series was issued c. 1876 and reinforced a neo-Romantic view of the Australian landscape to which a growing nationalist movement would respond. Nicholas Caire was active as a photographer in Australia from 1858 until his death in 1918. His vision of the Australian bush and pioneer life had a counterpart in the works of Henry Lawson and other nationalist poets, authors and painters.Albumen Silver Photograph on Boardprinted in ink on support l.c.: VIEW OF THE "HANGING ROCK," NEAR MOUNT MACEDON. / COPYRIGHT REGISTERED. printed in ink (vertically) on support reverse u.c.l.: J.W.

Geological specimen - Basalt, Unknown
... Basalt is a common igneous rock that composes most...-country Basalt is a common igneous rock that composes most ...Basalt is a common igneous rock that composes most of the Earth's surface and can be found on the Moon and other rocky planets of the Solar System. It is generally composed minerals such as calcic plagioclase, clinopyroxene and iron ore which form grains that are indistinguishable to the naked eye. It can be dark grey or black in colouring and sometimes may contain holes left by gas bubbles. Most of the Earth's basalt was produced in environments such as oceanic divergent boundaries, oceanic hotspots, and mantle plumes and hotspots beneath continents. Basalt is commonly used in construction where it is crushed and used for multiple purposes such as concrete aggregate, road base, or railroad ballast. Thin slabs of basalt can also be cut and used for floor tiles, stone monuments, and building veneer. This particular specimen was excavated from Talbot in Victoria, which was a small gold mining town established in 1852. As basalt is a common rock, it is not specific to Talbot. However, this specimen can be assumed to be of the Cainozoic age due to previous geomorphic surveys of the area. This particular type of Basalt was used mainly for roads due to the durability of the rock.Basalt holds significance due to the continued use of the rock from historic until present times. The rock has been utilised for many types of construction and is still used for the same purposes today. Basalt also has significance to the Earth and other rocky planets of the Solar System as it makes up most of the planet's surface. 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.

axe head
Inspected by Joanna Freslov, archaeologist 2.6.2008. Ground-edged axes first appeared in south-eastern Australia about 4,000 years ago and were used either with handles or hand-held. Stone tools were used for a variety of purposes, in ways similar to those of steel knives, axes, hammers and chisels. Ground-edge tools are made from fracture-resistant stone, such as basalt. This is able to withstand repeated impact making it suitable for use in objects such as stone axes. The stone was quarried, and then roughly shaped into a tool blank with blows from a hammerstone. The edges were then sharpened and refined by grinding the tool against a coarse, gritty rock. The necessary tools and equipment for hunting, fishing and warfare were one of the very few items that Aboriginals carried with them from place to place. Most were used for a multiplicity of purposes. Because many were made from raw natural materials, such as wood, generally only partial remains are found today.

Slide - Dunn's Rock Eppalock, 2012
The low rolling hills of the Kimbolton countryside consist of ancient, hard and fractured Ordovician rock up to 65 million years old, which was originally deposited deep under the sea. Rocks mainly are sandstone, mudstone, black shale and quartz conglomerates. Marine fossils can be found in the area. Around seven million years ago a basalt flow buried the original bedrock along the along the Campaspe River. Ongoing weathering, wind and water movement over the following years has produced younger clay, sand, silt and gravel deposits throughout the area. Patches of White Hills Gravel are also found in the area. Another unique geological feature of this area is the Permian Glacial Pavement rocks north and south of Eppalock and glacial sediments (such as “Dunn’s Rock” and “Kellams Rock”). During the ice age (up to 280 million years ago) large glaciers moving over the countryside, scoured out sediments, pulverized bedrock, polished and cut grooves into bedrock in the direction of ice movement. When the ice melted boulders etc where left behind in areas of entirely different rock types, such as a 100 Tonne granite block known as ‘The Stranger’ near Derrinal.
