Princess Sodalite Mine
Princess Sodalite Mine (previously the Princess Sodalite Quarry) is a sodalite quarry and retail shop, located near Bancroft, Ontario. The sodalite deposit was first discovered in 1892. Nomenclature and history The mineral deposit was first found by Frank Dawson Adams in 1892.Gem, Kitchener-Waterloo.''Mineral of the Month: SODALITE''" (2006). Sodalite from the quarry was displayed at the Columbian Exposition in Chicago in 1893. The Princess of Wales was given a gift of sodalite from the quarry in 1901 at the Pan-American Exposition in Buffalo, New York. She liked it so much that she ordered a shipment to decorate Marlborough House, in London, England. Thomas Morrison, the quarry's owner at the time, named the quarry the Princess Sodalite Quarry after her visit. The ''Quarry'' name continued through the 20th century until at least 2002. In 1999, the owners of the quarry donated a sodalite boulder to the Earth Sciences Museum at the University of Waterloo in Ontario.The quarry ...

Sodalite
Sodalite ( ) is a tectosilicate mineral with the formula , with royal blue varieties widely used as an wikt:ornamental, ornamental gemstone. Although massive sodalite samples are opaque, crystals are usually transparent to translucent. Sodalite is a member of the sodalite group with hauyne, nosean, lazurite and tugtupite. First discovered by Europeans in 1811 in the Ilimaussaq intrusive complex in Greenland, sodalite did not become important as an ornamental stone until 1891 when vast deposits of fine material were discovered in Ontario, Canada. Structure The structure of sodalite was first studied by Linus Pauling in 1930. It is a cubic mineral of space group P3n (:Minerals in space group 218, space group 218) which consists of an aluminosilicate cage network with Na+ cations and chloride anions in the interframework. (There may be small amounts of other cations and anions instead.) This framework forms a zeolite cage structure. Each unit cell has two cavities, which have alm ...

Mining Companies Of Canada
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, an ...

1892 In Ontario
Year 189 ( CLXXXIX) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Silanus and Silanus (or, less frequently, year 942 ''Ab urbe condita''). The denomination 189 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Quarrying
A quarry is a type of open-pit mine in which dimension stone, rock, construction aggregate, riprap, sand, gravel, or slate is excavated from the ground. The operation of quarries is regulated in some jurisdictions to reduce their environmental impact. The word ''quarry'' can also include the underground quarrying for stone, such as Bath stone. Types of rock Types of rock extracted from quarries include: *Chalk *China clay *Cinder *Clay *Coal *Construction aggregate (sand and gravel) * Coquina *Diabase *Gabbro *Granite * Gritstone *Gypsum *Limestone *Marble *Ores *Phosphate rock *Quartz *Sandstone *Slate *Travertine Stone quarry Stone quarry is an outdated term for mining construction rocks (limestone, marble, granite, sandstone, etc.). There are open types (called quarries, or open-pit mines) and closed types ( mines and caves). For thousands of years, only hand tools had been used in quarries. In the 18th century, the use of drilling and blasting operations was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gneiss
Gneiss ( ) is a common and widely distributed type of metamorphic rock. It is formed by high-temperature and high-pressure metamorphic processes acting on formations composed of igneous or sedimentary rocks. Gneiss forms at higher temperatures and pressures than schist. Gneiss nearly always shows a banded texture characterized by alternating darker and lighter colored bands and without a distinct cleavage. Gneisses are common in the ancient crust of continental shields. Some of the oldest rocks on Earth are gneisses, such as the Acasta Gneiss. Description Orthogneiss from the Czech Republic In traditional English and North American usage, a gneiss is a coarse-grained metamorphic rock showing compositional banding (gneissic banding) but poorly developed schistosity and indistinct cleavage. In other words, it is a metamorphic rock composed of mineral grains easily seen with the unaided eye, which form obvious compositional layers, but which has only a weak tendency to fracture ...

Nepheline
Nepheline, also called nephelite (), is a rock-forming mineral in the feldspathoid groupa silica-undersaturated aluminosilicate, Na3 K Al4 Si4 O16, that occurs in intrusive and volcanic rocks with low silica, and in their associated pegmatites. It is used in glass and ceramic manufacturing and other industries, and has been investigated as an ore of aluminium. Description and properties Nepheline crystals are rare and belong to the hexagonal system, usually having the form of a short, six-sided prism terminated by the basal plane. The crystals appear to have more symmetry than they actually possess, but unsymmetrical etched figures produced artificially on the prism faces indicate that the crystals are hemimorphic and tetartohedral, the only element of symmetry being a polar hexad axis. Nepheline is found in compact, granular aggregates, and can be white, yellow, gray, green, or reddish. Its hardness on the Mohs scale is 5.5–6, and its specific gravity 2.60–2.65. It i ...

Ontario Highway 28
King's Highway 28, commonly referred to as Highway 28, is a provincially maintained highway in the Canadian province of Ontario. The southwest–northeast route extends from Highway 7 east of Peterborough, to Highway 41 in Denbigh. The route passes over undulating hills before entering the Canadian Shield near Burleigh Falls, and gradually turns eastward. Highway 28 was assigned in 1928, incorporating Highway 12A, one of the original provincial highways. It was extended in the following decade, first to Apsley and then to a new Department of Roads and Northern Development centre in Bancroft. In the early 1980s, Highway 500 was added as an extension, reaching Denbigh. Portions of the highway were decommissioned or transferred in the 1990s, and in 2003 Highway 134 was added, extending the southern terminus to Highway 7. Route description Highway 28 begins at an intersection with Highway 7 approximately east of Peterborough. The road that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
