History Tharwa is the oldest official settlement in the Australian Capital Territory, proclaimed a settlement in 1862. Tharwa was named after the Aboriginal word for Mount Tennent, a nearby mountain peak which is part of Namadgi National Park. Mount Tennent was named after John Tennant, who was one of the earliest and best-known bushrangers in the r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Murrumbidgee River
The Murrumbidgee River () is a major tributary of the Murray River within the Murray–Darling basin and the second longest river in Australia. It flows through the Australian state of New South Wales and the Australian Capital Territory, descending over , generally in a west-northwesterly direction from the foot of Peppercorn Hill in the Fiery Range of the Snowy Mountains towards its confluence with the Murray River near Boundary Bend. The word ''Murrumbidgee'' or ''Marrmabidya'' means "big water" in the Wiradjuri language, one of the local Australian Aboriginal languages. The river itself flows through several traditional Aboriginal Australian lands, home to various Aboriginal peoples. In the Australian Capital Territory, the river is bordered by a narrow strip of land on each side; these are managed as the Murrumbidgee River Corridor (MRC). This land includes many nature reserves, eight recreation reserves, a European heritage conservation zone and rural leases. Flow The ...

Norfolk Island
Norfolk Island (, ; Norfuk: ''Norf'k Ailen'') is an external territory of Australia located in the Pacific Ocean between New Zealand and New Caledonia, directly east of Australia's Evans Head and about from Lord Howe Island. Together with the neighbouring Phillip Island and Nepean Island, the three islands collectively form the Territory of Norfolk Island. At the 2021 census, it had inhabitants living on a total area of about . Its capital is Kingston. The first known settlers in Norfolk Island were East Polynesians but they had already departed when Great Britain settled it as part of its 1788 settlement of Australia. The island served as a convict penal settlement from 6 March 1788 until 5 May 1855, except for an 11-year hiatus between 15 February 1814 and 6 June 1825, when it lay abandoned. On 8 June 1856, permanent civilian residence on the island began when descendants of the ''Bounty'' mutineers were relocated from Pitcairn Island. In 1914 the UK handed Norfo ...

Australian Alps Walking Track
The Australian Alps Walking Track is a long-distance walking trail through the alpine areas of Victoria, New South Wales and ACT. It is 655 km long, starting at Walhalla, Victoria and running through to Tharwa, ACT near Canberra. The track weaves mainly through Australian national parks, such as Alpine National Park and Kosciuszko National Park, though it is not exclusively restricted to national parks. It ascends many peaks including Mount Kosciuszko, Mount Bogong, and Bimberi Peak, the highest points in N.S.W., Victoria, and the A.C.T. respectively. The AAWT crosses exposed high plains including the Victorian Bogong High Plains and the Main Range in NSW. To walk the whole trail can take between 5 and 8 weeks. Food drops or a support crew are necessary, as the trail passes through no towns, although it passes close to the ski resorts of Mt Hotham, Falls Creek, Mt Baw Baw, Thredbo, Charlotte Pass and Perisher. It has been signposted for part of its length in a tri-state ag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Magnetic Declination
Magnetic declination, or magnetic variation, is the angle on the horizontal plane between magnetic north (the direction the north end of a magnetized compass needle points, corresponding to the direction of the Earth's magnetic field lines) and true north (the direction along a meridian towards the geographic North Pole). This angle varies depending on position on the Earth's surface and changes over time. Somewhat more formally, Bowditch defines variation as “the angle between the magnetic and geographic meridians at any place, expressed in degrees and minutes east or west to indicate the direction of magnetic north from true north. The angle between magnetic and grid meridians is called grid magnetic angle, grid variation, or grivation.” By convention, declination is positive when magnetic north is east of true north, and negative when it is to the west. ''Isogonic lines'' are lines on the Earth's surface along which the declination has the same constant value, and line ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geoid
The geoid () is the shape that the ocean surface would take under the influence of the gravity of Earth, including gravitational attraction and Earth's rotation, if other influences such as winds and tides were absent. This surface is extended through the continents (such as with very narrow hypothetical canals). According to Carl Friedrich Gauss, Gauss, who first described it, it is the "mathematical figure of the Earth", a smooth but irregular surface whose shape results from the uneven distribution of mass within and on the surface of Earth. It can be known only through extensive gravitational measurements and calculations. Despite being an important concept for almost 200 years in the history of geodesy and geophysics, it has been defined to high precision only since advances in satellite geodesy in the late 20th century. All points on a geoid surface have the same geopotential (the sum of gravitational energy, gravitational potential energy and centrifugal force, centrifug ...

Mica
Micas ( ) are a group of silicate minerals whose outstanding physical characteristic is that individual mica crystals can easily be split into extremely thin elastic plates. This characteristic is described as perfect basal cleavage. Mica is common in igneous and metamorphic rock and is occasionally found as small flakes in sedimentary rock. It is particularly prominent in many granites, pegmatites, and schists, and "books" (large individual crystals) of mica several feet across have been found in some pegmatites. Micas are used in products such as drywalls, paints, fillers, especially in parts for automobiles, roofing and shingles, as well as in electronics. The mineral is used in cosmetics and food to add "shimmer" or "frost." Properties and structure The mica group is composed of 37 phyllosilicate minerals. All crystallize in the monoclinic system, with a tendency towards pseudohexagonal crystals, and are similar in structure but vary in chemical composition. Micas are ...

Biotite
Biotite is a common group of phyllosilicate minerals within the mica group, with the approximate chemical formula . It is primarily a solid-solution series between the iron-endmember annite, and the magnesium-endmember phlogopite; more aluminous end-members include siderophyllite and eastonite. Biotite was regarded as a mineral ''species'' by the International Mineralogical Association until 1998, when its status was changed to a mineral ''group''. The term ''biotite'' is still used to describe unanalysed dark micas in the field. Biotite was named by J.F.L. Hausmann in 1847 in honor of the French physicist Jean-Baptiste Biot, who performed early research into the many optical properties of mica. Members of the biotite group are sheet silicates. Iron, magnesium, aluminium, silicon, oxygen, and hydrogen form sheets that are weakly bound together by potassium ions. The term "iron mica" is sometimes used for iron-rich biotite, but the term also refers to a flaky micaceous form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adamellite
Quartz monzonite is an intrusive, felsic, igneous rock that has an approximately equal proportion of orthoclase and plagioclase feldspars. It is typically a light colored phaneritic (coarse-grained) to porphyritic granitic rock. The plagioclase is typically intermediate to sodic in composition, andesine to oligoclase. Quartz is present in significant amounts. Biotite and/or hornblende constitute the dark minerals. Because of its coloring, it is often confused with granite, but whereas granite contains more than 20% quartz, quartz monzonite is only 5–20% quartz. Rock with less than five percent quartz is classified as monzonite. A rock with more alkali feldspar is a syenite whereas one with more plagioclase is a quartz diorite.Classification of Igneous Rocks The fine grained |
Leopold Fane De Salis
Leopold Fabius Dietegen Fane de Salis, (26 April 1816 – 20 November 1898) was a Tuscan-born Australian pastoralist and politician. Born in Florence to Jerome, 4th Count de Salis-Soglio and Henrietta Foster, he attended Eton College and studied sheep farming at Jedburgh in Scotland. In 1840 he migrated to Sydney, where he formed a partnership to run a station at Junee. In the same decade, in 1842, 1844 and 1848, his highly capable next elder brother William also sailed to Australia. They did much business together. In 1844 he married Charlotte Macdonald, with whom he had four children, two of whom (George and Leopold) would later become politicians themselves. In 1855 he sold out and bought the Cuppacumbalong station at Tharwa, later purchasing further property on the Murrumbidgee River. In 1864 he was elected to the New South Wales Legislative Assembly for Queanbeyan, but he did not re-contest in 1869. In 1872 he was appointed to the New South Wales Legislative Council. ...

William Farrer
William James Farrer (3 April 184516 April 1906) was a leading English Australian agronomist and plant breeder. Farrer is best remembered as the originator of the "Federation" strain of wheat, distributed in 1903. His work resulted in significant improvements in both the quality and crop yields of Australia's national wheat harvest, a contribution for which he earned the title 'father of the Australian wheat industry'. Early years Farrer was born on 3 April 1845 in the town of Docker, Westmorland in the English north west (now Cumbria). The son of Thomas Farrer, a tenant farmer, and his wife Sarah William, William Farrer was selected for a scholarship at Christ's Hospital, London where he was awarded a gold and silver medal for mathematics and soon earned a scholarship to Pembroke College where, after earning a B.A. at Pembroke College, Cambridge in 1868, Farrer emigrated to Australia in 1870. A sufferer of tuberculosis, Farrer hoped to find Australia's drier warmer climate mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
