West Coast Range
The West Coast Range is a mountain range located in the West Coast region of Tasmania, Australia. The range lies to the west and north of the main parts of the Franklin-Gordon Wild Rivers National Park. The range has had a significant number of mines utilising the geologically rich zone of Mount Read Volcanics. A number of adjacent ranges lie to the east: the Engineer Range, the Raglan Range, the Eldon Range, and the Sticht Range but in most cases these are on a west–east alignment, while the West Coast Range runs in a north–south direction, following the Mount Read volcanic arc. The range has encompassed multiple land uses including the catchment area for Hydro Tasmania dams, mines, transport routes and historical sites. Of the communities that have existed actually in the range itself, Gormanston, is probably the last to remain. Geographical features These are determined by a number of factors - the southerly direction of glaciation in the King River V ...

West Coast, Tasmania
The West Coast of Tasmania is mainly isolated rough country, associated with wilderness, mining and tourism. It served as the location of an early convict settlement in the early history of Van Diemen's Land, and contrasts sharply with the more developed and populous northern and eastern parts of the island state. Climate The west coast has a much cooler and wetter climate when compared to the east coast. Frequent low pressure systems hit the west coast causing heavy rain, snow, and ice. The West Coast Range blocks these systems from impacting the east, therefore making the West Coast a rain catchment with some areas receiving over of rain a year. In winter temperatures at sea level hover around , and when not raining, morning frost is common. The temperatures are much lower inland from the coast with maximums in winter often failing to surpass . Typically, the snow line in winter is around 900 metres (3000 ft), however sea level snow falls several times each winter as ...

Australian Height Datum
The Australian Height Datum was introduced in 1971 as the official vertical datum for Australia, and thereby serves as the benchmark to which all height measurements are referred. The Australian Height Datum is an amalgamation of decades of spirit levelling work conducted by numerous state and territory authorities across the country, and was corrected to align with the mean sea level observations of thirty tide gauges positioned around the entire coastline. While it remains the published vertical datum for all surveying and engineering operations performed throughout Australia, newer technologies have uncovered numerous deficiencies, offsets and distortions within the Australian Height Datum, leading to discussions about defining a new Australian vertical datum. Background The National Mapping Council (pre-1945) Prior to the creation of the Australian Height Datum, levelling surveys were carried out by professional surveyors for construction and mapping purposes using only ...

Shield Volcano
A shield volcano is a type of volcano named for its low profile, resembling a warrior's shield lying on the ground. It is formed by the eruption of highly fluid (low viscosity) lava, which travels farther and forms thinner flows than the more viscous lava erupted from a stratovolcano. Repeated eruptions result in the steady accumulation of broad sheets of lava, building up the shield volcano's distinctive form. Shield volcanoes are found wherever fluid low-silica lava reaches the surface of a rocky planet. However, they are most characteristic of ocean island volcanism associated with hot spots or with continental rift volcanism. They include the largest volcanoes on earth, such as Tamu Massif and Mauna Loa. Giant shield volcanoes are found on other planets of the Solar System, including Olympus Mons on Mars and Sapas Mons on Venus. Etymology The term 'shield volcano' is taken from the German term ''Schildvulkan'', coined by the Austrian geologist Eduard Suess in 1888 an ...

Mount Read Volcanics
The Mount Read Volcanics is a Cambrian volcanic belt that exists in Western Tasmania. It is a complex belt due to folding, faulting and a range of tectonic events. It is a productive mineralised belt that has profitable copper-silver and gold production of Mount Lyell, Rosebery, and Henty Gold Mine ; and numerous smaller sites of prospective mineralisation along the West Coast Range.

Volcanoes Of Tasmania
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 ...
