Tachylite In Victorian Archaeological Sites
Tachylite is an unusual and relatively rare stone used in making flaked stone tools, and which is found in Aboriginal archaeological sites in Victoria, Australia. It was sourced from Spring Hill near Lauriston, Victoria, and there is another historical reference to a source at Green Hill near Trentham, Victoria, but the exact location has not been confirmed. Daniel James Mahony described ''...water worn pebbles of pitchstone, a highly silicious volcanic glass associated with tachylite on the Coliban River. ''Mitchell refers to the distribution of the material with: ''Small artefacts are common at Willaura, Burrumbeet, Inverleigh, Point Cook and as far north as Dooen near Horsham''. Since 2016 the material is found on further sites on the traditional lands of the Dja Dja Wurrung who were well regarded by other groups for the hard glassy stone that all valued and traded to use for superior stone weapons and tools. Examples are held in the collection of the Castlemaine Art ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tachylite
Tachylite ( ; also spelled tachylyte) is a form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt. It is a type of mafic igneous rock that is chemical decomposition, decomposable by acids and readily melting, fusible. The color is a black or dark-brown, and it has a greasy-looking, resinous lustre (mineralogy), luster. It is very brittleness, brittle and occurs in dike (geology), dikes, vein (geology), veins, and igneous intrusion, intrusive masses. The word originates from the Ancient Greek , meaning "swift". Tachylites have the appearance of pitch (resin), pitch and are often more or less vesicular texture, vesicular and sometimes apherulite, spherulitic. They are very brittle and break down readily under a hammer. Small crystals of feldspar or olivine are sometimes visible in them with the unaided eye. All tachylites weathering, weather rather easily and by oxidation of their iron become dark brown or red. Three modes of occurren ...

Dja Dja Wurrung
Dja Dja Wurrung (Pronounced Ja-Ja-war-rung), also known as the Djaara or Jajowrong people and Loddon River tribe, are an Aboriginal Australian people who are the Traditional owners of lands including the watersheds of the Loddon and Avoca rivers in the Bendigo region of central Victoria, Australia. They are part of the Kulin alliance of Aboriginal Victorian peoples. There are 16 clans, which adhere to a patrilineal system. Like other Kulin peoples, there are two moieties: Bunjil the eagle and Waa the crow. Name The Dja Dja Wurrung ethnonym is often analysed as a combination of a word for "yes" (''djadja'', dialect variants such as ''yeye'' /''yaya'', are perhaps related to this) and "mouth" (''wurrung''). This is quite unusual, since many other languages of the region define their speakers in terms of the local word for "no". It had, broadly speaking, two main dialects, an eastern and western variety. Language Dja Dja Wurrung is classified as one of the Kulin languages. So ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Archaeological Sites In Victoria (state)
Archaeology or archeology is the scientific study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology is distinct from palaeontology, which is the study of fossil remains. Archaeology is particularly important for learning about prehistoric societies, for which, by definition, there are no written records. Prehistory includes over 99% of the human past, from the Paleolithic until ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic Glass
Volcanic glass is the amorphous (uncrystallized) product of rapidly cooling magma. Like all types of glass, it is a state of matter intermediate between the closely packed, highly ordered array of a crystal and the highly disordered array of liquid. Volcanic glass may refer to the interstitial material, or matrix, in an aphanitic (fine-grained) volcanic rock, or to any of several types of vitreous igneous rocks. Origin Volcanic glass is formed when magma is rapidly cooled. Magma rapidly cooled to below its normal crystallization temperature becomes a supercooled liquid, and, with further rapid cooling, this becomes an amorphous solid. The change from supercooled liquid to glass occurs at a temperature called the glass transition temperature, which depends on both cooling rate and the amount of water dissolved in the magma. Magma rich in silica and poor in dissolved water is most easily cooled rapidly enough to form volcanic glass. As a result, rhyolite magmas, which are high in s ...

The Argus (Melbourne)
''The Argus'' was an Australian daily morning newspaper in Melbourne from 2 June 1846 to 19 January 1957, and was considered to be the general Australian newspaper of record for this period. Widely known as a conservative newspaper for most of its history, it adopted a left-leaning approach from 1949. ''The Argus''s main competitor was David Syme's more liberal-minded newspaper, ''The Age''. History The newspaper was originally owned by William Kerr, who was also Melbourne's town clerk from 1851–1856 and had been a journalist at the ''Sydney Gazette'' before moving to Melbourne in 1839 to work on John Pascoe Fawkner's newspaper, the '' Port Phillip Patriot''. The first edition was published on 2 June 1846. The paper soon became known for its scurrilous abuse and sarcasm, and by 1853, after he had lost a series of libel lawsuits, Kerr was forced to sell the paper's ownership to avoid financial ruin. The paper was then published by Edward Wilson. By 1855, it had a daily c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Liptrap
Cape Liptrap is located in south Gippsland, Victoria and is a peninsula that is the extension of the Hoddle Range that runs out to sea in a southwesterly direction. With a latitude of 38° 53' 60" S it the second most southerly point on the Australian mainland, just south of Cape Otway which lies to the west. Wilsons Promontory which is the most southerly point sits to the southeast separated from Cape Liptrap by Waratah Bay. It was sighted by Lieutenant James Grant on 9 December 1800 from the survey brig HMS Lady Nelson and named after John Liptrap. Cape Liptrap sits high above the Bass Strait with steep slopes and cliffs of folded marine sediments flanked by rock pinnacles and wave cut platforms. At the end of the peninsula is Cape Liptrap Lighthouse that was built in 1951 in cast concrete, and is octagonal in shape. Surrounding Townships To the east of Cape Liptrap are the townships of Walkerville , Sandy Point and Waratah Bay. To the northwest is Venus Bay, the Ta ...

William Henry Gill (ethnographer)
William Henry Gill (1861–1944) was an Australian ethnographer, collector of Aboriginal artefacts, and art dealer. Ethnographic activities Gill was prolific in recording information about Australian Aboriginal culture and artefacts in Tasmania and mainland Australia. His papers were compiled by the Mitchell Library and constitute an important early ethnographic record. He was particularly concerned with the customs of Aboriginal people of the Dieri, Wonkonguru and Yaurorka tribes of the Lake Eyre region of South Australia and corresponded with George Aiston, a police officer stationed to the north and east of Lake Eyre, Central Australia. He also corresponded with C. L. Willes about early Tasmanian records and Tasmanian aborigines and with Daisy Bates. Art dealer Gill also ran a business as a fine art dealer, with connections to artists including Norman Lindsay, George Washington Lambert, Tom Roberts and Arthur Streeton. He ran the Fine Art Society, in Melbourne, Victoria, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phenocrysts
300px, feldspathic phenocrysts. This granite, from the Switzerland">Swiss side of the Mont Blanc massif, has large white plagioclase phenocrysts, triclinic minerals that give trapezoid shapes when cut through). 1 euro coins, 1 euro coin (diameter 2.3 cm) for scale. A phenocryst is an early forming, relatively large and usually conspicuous crystal distinctly larger than the grains of the rock groundmass of an igneous rock. Such rocks that have a distinct difference in the size of the crystals are called porphyries, and the adjective porphyritic is used to describe them. Phenocrysts often have euhedral forms, either due to early growth within a magma, or by post-emplacement recrystallization. Normally the term ''phenocryst'' is not used unless the crystals are directly observable, which is sometimes stated as greater than .5 millimeter in diameter. Phenocrysts below this level, but still larger than the groundmass crystals, are termed ''microphenocrysts''. Very large phenocrysts a ...

Basalt
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...
