Mount Noorat
Mount Noorat is a dormant volcano, situated on Glenormiston Road north of the township of Noorat, and approximately six kilometres north of Terang, Victoria, Australia. The last eruption is estimated to have occurred between 5,000 and 20,000 years ago. Mount Noorat is a major volcano of the Newer Volcanics Province of Victoria, with a peak height of 310 metres above sea level and a crater between 160 and 200 metres. It is characterised by multiple vents, a complex topography, and the deepest scoria enclosed crater in Victoria. The mount illustrates a transition from maar eruption to scoria cone development, and includes megacryst and xenolith. Legacy The Mount was historically a traditional meeting and trading place for the district's Indigenous peoples, the Kirrae Wuurong, who exchanged stones, spears, skins and other material. Its scoria was used on the district's early roads. See also * List of mountains in Victoria *List of volcanoes in Australia This is a lis ...

Scoria Cone
Scoria is a pyroclastic, highly vesicular, dark-colored volcanic rock that was ejected from a volcano as a molten blob and cooled in the air to form discrete grains or clasts.Neuendorf, K.K.E., J.P. Mehl, Jr., and J.A. Jackson, eds. (2005) ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. It is typically dark in color (generally dark brown, black or purplish-red), and basaltic or andesitic in composition. Scoria is relatively low in density as a result of its numerous macroscopic ellipsoidal vesicles, but in contrast to pumice, all scoria has a specific gravity greater than 1, and sinks in water. The holes or vesicles form when gases that were dissolved in the magma come out of solution as it erupts, creating bubbles in the molten rock, some of which are frozen in place as the rock cools and solidifies. Scoria may form as part of a lava flow, typically near its surface, or as fragmental ejecta (lapilli, blocks and bombs), for ins ...

Tourist Attractions In Victoria (state)
Tourism is travel for pleasure or business; also the theory and practice of touring, the business of attracting, accommodating, and entertaining tourists, and the business of operating tours. The World Tourism Organization defines tourism more generally, in terms which go "beyond the common perception of tourism as being limited to holiday activity only", as people "travelling to and staying in places outside their usual environment for not more than one consecutive year for leisure and not less than 24 hours, business and other purposes". Tourism can be domestic (within the traveller's own country) or international, and international tourism has both incoming and outgoing implications on a country's balance of payments. Tourism numbers declined as a result of a strong economic slowdown (the late-2000s recession) between the second half of 2008 and the end of 2009, and in consequence of the outbreak of the 2009 H1N1 influenza virus, but slowly recovered until the COVI ...

Volcanoes Of Victoria (state)
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide pa ...

List Of Volcanoes In Australia
This is a list of active, dormant and extinct volcanoes in Australia and its island territories. Note that the term volcano is used loosely as it can include groups of related volcanoes and vents that erupted at similar times with lava of related origin. The lists provided below are mainly volcanoes of Cenozoic aged, with some notable older (Mesozoic and Paleozoic aged), volcanoes included. There are no volcanoes on the Australian mainland that have erupted since European settlement, but some volcanoes in Victoria, South Australia and North Queensland could have been witnessed by Aboriginal people several thousand years ago. There are active volcanoes in the Heard and McDonald Islands. Australian states Queensland New South Wales Victoria South Australia South Australia's volcanoes are the youngest in Australia, and erupted within the memory of local Indigenous peoples. They are all in the Limestone Coast region, in the Mount Burr Range. They are considered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kirrae Wuurong
The Girai wurrung, also spelt Kirrae Wuurong and Kirrae Whurrung, are an Aboriginal Australian people who traditionally occupied the territory between Mount Emu Creek and the Hopkins River up to Mount Hamilton, and the Western Otways from the Gellibrand River to the Hopkins River. The historian Ian D. Clark has reclassified much of the material regarding them in Norman Tindale's compendium under the Djargurd Wurrung, a term reflecting the assumed pre-eminence of one of their clans, the Jacoort/Djargurd. Language The Giray language (''Girai wurrung'' meaning literally "blood lip language") spoke a dialect of Dhauwurd Wurrung language ("the Warrnambool language"), which belongs to the Kulinic branch of the Pama-Nyungan language family. James Dawson and his daughter Isabella took down extensive vocabulary lists of it and related dialects. A dictionary of the language was compiled in the 1990s. Country The Girai lands comprised of territory from Warrnambool and Hopkins River ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xenolith
A xenolith ("foreign rock") is a rock fragment ( country rock) that becomes enveloped in a larger rock during the latter's development and solidification. In geology, the term ''xenolith'' is almost exclusively used to describe inclusions in igneous rock entrained during magma ascent, emplacement and eruption. Xenoliths may be engulfed along the margins of a magma chamber, torn loose from the walls of an erupting lava conduit or explosive diatreme or picked up along the base of a flowing body of lava on the Earth's surface. A xenocryst is an individual foreign crystal included within an igneous body. Examples of xenocrysts are quartz crystals in a silica-deficient lava and diamonds within kimberlite diatremes. Xenoliths can be non-uniform within individual locations, even in areas which are spatially limited, e.g. rhyolite-dominated lava of Niijima volcano ( Japan) contains two types of gabbroic xenoliths which are of different origin - they were formed in different tempe ...

Megacryst
In geology, a megacryst is a crystal or grain that is considerably larger than the encircling matrix. They are found in igneous and metamorphic rocks. Megacrysts can be further classified based on the nature of their origin, either as:Chapman, Carleton A. (2014). Phenocryst. In AccessScience. McGraw-Hill Education. https://doi.org/10.1036/1097-8542.506500 *Phenocrysts, which crystallize in molten rock material (lava or magma) and are hence an earlier crystallization than the matrix in which they are embedded *Porphyroblasts, which develop in solid rock as the result of metamorphism or metasomatism See also *Xenolith A xenolith ("foreign rock") is a rock fragment ( country rock) that becomes enveloped in a larger rock during the latter's development and solidification.

Maar
A maar is a broad, low-relief volcanic crater caused by a phreatomagmatic eruption (an explosion which occurs when groundwater comes into contact with hot lava or magma). A maar characteristically fills with water to form a relatively shallow crater lake which may also be called a maar. The name comes from a Moselle Franconian dialect word used for the circular lakes of the Daun area of Germany. Notes: * According to German Wikipedia's ''"Maar"'' article, in 1544 in his book ''Cosmographia'', Sebastian Münster (1488–1552) first applied the word "maar" (as ''Marh'') to the Ulmener Maar and the Laacher See. See: Sebastian Münster, ''Cosmographia'' (Basel, Switzerland: Heinrich Petri, 1544)p. 341. From p. 341: ''"Item zwen namhafftiger seen seind in der Eyfel / einer bey de schloß Ulmen / und ein ander bey dem Closter züm Laich / die seind sere tieff / habe kein ynflüß aber vil außflüß / die nennet man Marh unnd seind fischreich."''
