Bancroft Rockbound Gemboree
The Bancroft Rockhound Gemboree is a four-day event in Bancroft, Ontario where mineral collectors and vendors meet to trade rocks and minerals. It has been occurring annually since 1963. Geology of Bancroft The geology around Bancroft is rich in mineral pegmatites, as a result of molten lava being trapped under the Canadian Shield one billion areas ago. The geology of Bancroft is noted for having bodies of quartz surrounded by rare earth minerals, including zircon and uraninite.Joyce, G. ''Rockhound heaven''.

Bancroft, Ontario
Bancroft () is a town located on the York River in Hastings County in the Canadian province of Ontario. It was first settled in the 1850s by United Empire Loyalists and Irish immigrants. From the mid-1950s to about 1982, mining was the primary industry. A village until 1999, Bancroft then merged with Dungannon Township to form the Town of Bancroft. The population at the time of the 2016 Census was 3,881; the regional population is 40,000. There are 150,000 visitors to Bancroft, annually. History By 1823, the government had purchased nearly two million acres of land from the Chippewa and Mississaga First Nations including a tract on the York River in Hastings County which had been established in 1792. The area was mapped in 1835 by explorer David Thompson. The first family to build a cabin here, the Clarks in 1853, did so to take advantage of the fur trade. Early settlers included James Cleak and Alfred Barker from England who arrived in 1855, settling on Quarry Lake. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pegmatite
A pegmatite is an igneous rock showing a very coarse texture, with large interlocking crystals usually greater in size than and sometimes greater than . Most pegmatites are composed of quartz, feldspar, and mica, having a similar silicic composition to granite. However, rarer intermediate composition and mafic pegmatites are known. Many of the world's largest crystals are found within pegmatites. These include crystals of microcline, quartz, mica, spodumene, beryl, and tourmaline. Some individual crystals are over long. Most pegmatites are thought to form from the last fluid fraction of a large crystallizing magma body. This residual fluid is highly enriched in volatiles and trace elements, and its very low viscosity allows molecules to migrate rapidly to join an existing crystal rather than coming together to form new crystals. This allows a few very large crystals to form. While most pegmatites have a simple composition of minerals common in ordinary igneous rock, a few ...

Canadian Shield
The Canadian Shield (french: Bouclier canadien ), also called the Laurentian Plateau, is a geologic shield, a large area of exposed Precambrian igneous and high-grade metamorphic rocks. It forms the North American Craton (or Laurentia), the ancient geologic core of the North American continent. Glaciation has left the area with only a thin layer of soil, through which exposures of igneous bedrock resulting from its long volcanic history are frequently visible. As a deep, common, joined bedrock region in eastern and central Canada, the Shield stretches north from the Great Lakes to the Arctic Ocean, covering over half of Canada and most of Greenland; it also extends south into the northern reaches of the United States. Geographical extent The Canadian Shield is a physiographic division comprising four smaller physiographic provinces: the Laurentian Upland, Kazan Region, Davis and James. The shield extends into the United States as the Adirondack Mountains (connected by the Fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zircon
Zircon () is a mineral belonging to the group of nesosilicates and is a source of the metal zirconium. Its chemical name is zirconium(IV) silicate, and its corresponding chemical formula is Zr SiO4. An empirical formula showing some of the range of substitution in zircon is (Zr1–y, REEy)(SiO4)1–x(OH)4x–y. Zircon precipitates from silicate melts and has relatively high concentrations of high field strength incompatible elements. For example, hafnium is almost always present in quantities ranging from 1 to 4%. The crystal structure of zircon is tetragonal crystal system. The natural color of zircon varies between colorless, yellow-golden, red, brown, blue, and green. The name derives from the Persian ''zargun'', meaning "gold-hued". This word is corrupted into "jargoon", a term applied to light-colored zircons. The English word "zircon" is derived from ''Zirkon'', which is the German adaptation of this word. Yellow, orange, and red zircon is also known as "hyacinth", ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uraninite
Uraninite, formerly pitchblende, is a radioactive, uranium-rich mineral and ore with a chemical composition that is largely UO2 but because of oxidation typically contains variable proportions of U3O8. Radioactive decay of the uranium causes the mineral to contain oxides of lead and trace amounts of helium. It may also contain thorium and rare-earth elements. Overview Uraninite used to be known as pitchblende (from '' pitch'', because of its black color, and ''blende'', from ''blenden'' meaning "to deceive", a term used by German miners to denote minerals whose density suggested metal content, but whose exploitation, at the time they were named, was either unknown or not economically feasible). The mineral has been known at least since the 15th century from silver mines in the Ore Mountains, on the German/Czech border. The type locality is the historic mining and spa town known as Joachimsthal, the modern day Jáchymov, on the Czech side of the mountains, where F. E. Brückma ...

Canadian Geographic
''Canadian Geographic'' is a magazine published by the Royal Canadian Geographical Society, (RCGS) based in Ottawa, Ontario. History and profile After the Society was founded in 1929, the magazine was established the next year in May 1930 under the name ''Canadian Geographical Journal''. The Society's objective was to produce a popular magazine primarily focusing on Canadian geography. The first editor was Charles Camsell, since 1915 a fellow of the British Royal Geographical Society, as well as a geologist who had been responsible for mapping large parts of Northern Ontario, Manitoba and the Yukon. Originally published out of Montreal, Quebec, the magazine is now headquartered in Ottawa, Ontario. The magazine adopted its current title in 1978. Typically the magazine contains articles on physical, historical, political and environmental geography, illustrated with photographs, illustrations and maps. Controversial subjects such as acid rain, clear-cut logging, vanishing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Canadian Legion
The Royal Canadian Legion is a non-profit Canadian ex-service organization (veterans' organization) founded in 1925. Membership includes people who have served as military, Royal Canadian Mounted Police, provincial and municipal police, Royal Canadian Air, Army and Sea Cadets, direct relatives of members and also affiliated members. Membership is now also open to the general public. History In Canada, several veterans' organisations emerged during the First World War. The Great War Veterans Association was by 1919 the largest veterans' organisation in Canada. Following the First World War, 15 different organisations existed to aid returning veterans in Canada. Field Marshal The 1st Earl Haig, founder of the British Empire Service League (now known as the Royal Commonwealth Ex-Services League), visited Canada in 1925 and urged the organisations to merge. In the same year, the Dominion Veterans Alliance was created to unite these organizations. In November 1925, the Canadian L ...

The Globe And Mail
''The Globe and Mail'' is a Canadian newspaper printed in five cities in western and central Canada. With a weekly readership of approximately 2 million in 2015, it is Canada's most widely read newspaper on weekdays and Saturdays, although it falls slightly behind the ''Toronto Star'' in overall weekly circulation because the ''Star'' publishes a Sunday edition, whereas the ''Globe'' does not. ''The Globe and Mail'' is regarded by some as Canada's " newspaper of record". ''The Globe and Mail''s predecessors, '' The Globe'' and ''The Mail and Empire'' were both established in the 19th century. The former was established in 1844, while the latter was established in 1895 through a merger of ''The Toronto Mail'' and the ''Toronto Empire''. In 1936, ''The Globe'' and ''The Mail and Empire'' merged to form ''The Globe and Mail''. The newspaper was acquired by FP Publications in 1965, who later sold the paper to the Thomson Corporation in 1980. In 2001, the paper merged with broadcast ...

Gemology
Gemology or gemmology is the science dealing with natural and artificial gemstone materials. It is a geoscience and a branch of mineralogy. Some jewelers (and many non-jewelers) are academically trained gemologists and are qualified to identify and evaluate gems. History Rudimentary education in gemology for jewellers and gemologists began in the nineteenth century, but the first qualifications were instigated after the National Association of Goldsmiths of Great Britain (NAG) set up a Gemmological Committee for this purpose in 1908. This committee matured into the Gemmological Association of Great Britain (also known as Gem-A), now an educational charity and accredited awarding body with its courses taught worldwide. The first US graduate of Gem-A's diploma course, in 1929, was Robert Shipley, who later established both the Gemological Institute of America and the American Gem Society. There are now several professional schools and associations of gemologists and certificatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
