The Canadian Shield, also called the Laurentian Plateau, or Bouclier canadien (French), is a large area of exposed Precambrian igneous and high-grade metamorphic rocks that forms the ancient geological core of the North American continent. Composed of igneous rock resulting from its long volcanic history, the area is covered by a thin layer of soil. With a deep, common, joined bedrock region in eastern and central Canada, it stretches north from the Great Lakes to the Arctic Ocean, covering over half of Canada; it also extends south into the northern reaches of the United States. Human population is sparse, and industrial development is minimal, while mining is prevalent.
Pentlandite is an iron-nickel sulfide, (Fe,Ni)9S8. Pentlandite has a narrow variation range in Ni:Fe but it is usually described as having a Ni:Fe of 1:1. It also contains minor cobalt, usually at low levels as a fraction of weight.
The platinum-group metals are six noble, precious metallic elements clustered together in the periodic table. These elements are all transition metals in the d-block.
The Sudbury Basin, also known as Sudbury Structure or the Sudbury Nickel Irruptive, is a major geological structure in Ontario, Canada. It is the third-largest known impact crater or astrobleme on Earth, as well as one of the oldest. The crater formed 1.849 billion years ago in the Paleoproterozoic era.
Lake Wanapitei occupies a meteorite crater in Sudbury, Ontario, Canada. It is located near the much larger Sudbury meteorite crater but they are not related.
Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine. The name norite is derived from Norge, the Norwegian name for Norway.
The Gunflint Range is an iron ore deposit in northern Minnesota in the United States and Northwestern Ontario, Canada. The range extends from the extreme northern portion of Cook County, Minnesota into the Thunder Bay District, Ontario.
Sperrylite is a platinum arsenide mineral with formula PtAs2 and is an opaque metallic tin white mineral which crystallizes in the isometric system with the pyrite group structure. It forms cubic, octahedral or pyritohedral crystals in addition to massive and reniform habits. It has a Mohs hardness of 6 - 7 and a very high specific gravity of 10.6.
Larvikite is an igneous rock, specifically a variety of monzonite, notable for the presence of thumbnail-sized crystals of feldspar. These feldspars are known as ternary because they contain significant components of all three endmember feldspars. The feldspar has partly unmixed on the micro-scale to form a perthite, and the presence of the alternating alkali feldspar and plagioclase layers give its characteristic silver blue sheen on polished surfaces. Olivine can be present along with apatite, and locally quartz. Larvikite is usually rich in titanium, with titanaugite and/or titanomagnetite present.
A lopolith is a large igneous intrusion which is lenticular in shape with a depressed central region. Lopoliths are generally concordant with the intruded strata with dike or funnel-shaped feeder bodies below the body. The term was first defined and used by Frank Fitch Grout during the early 1900s in describing the Duluth gabbro complex in northern Minnesota and adjacent Ontario.
Anthony James "Tony" Naldrett, FRSC is a Canadian geologist. He is an authority on the geology and origin of nickel-copper-platinum group element deposits, the tectonic setting in which they occur, the petrology of associated rocks, and controls on their composition. He is considered an expert on the reaction between sulfide and silicate melts, fractional crystallization of sulfide melts, and the role of hydrothermal fluids.
Nickel Belt is a provincial electoral district located in the Canadian province of Ontario. It elects one member to the Legislative Assembly of Ontario. The district is located in Northern Ontario and includes much of the eastern and southern parts of the District of Sudbury, as well as most of Greater Sudbury outside the city's urban core. Communities include Lively, Onaping, Levack, Dowling, Chelmsford, Naughton, Azilda, Coniston, Wahnapitae, Garson, Val Caron, Val Thérèse, Hanmer and Capreol.
The Nipissing sills, also called the Nipissing diabase, is a large 2217– to 2210–million year old group of sills in the Superior craton of the Canadian Shield in Ontario, Canada, which intrude the Huronian Supergroup. Nipissing sills intrude all the Huronian sediments and older basement rocks in the northern margin of the Sudbury Basin; they were emplaced after the faulting and folding of Huronian rocks, and are hornblende gabbro of tholeiitic basalt composition. In the Sudbury–Elliot Lake area the Nipissing diabase is deformed; outcrops are parallel to the fold axes of the Huronian sedimentary rocks. Nipissing diabase intrusions are east-northeast trending and are no wider than 460 m (1,510 ft).
Mars may contain ores that would be very useful to potential colonists. The abundance of volcanic features together with widespread cratering are strong evidence for a variety of ores. While nothing may be found on Mars that would justify the high cost of transport to Earth, the more ores that future colonists can obtain from Mars, the easier it would be to build colonies there.
The Southern Province is a portion of Proterozoic rock that ranges in age from 2.5 billion to 600 million years old. It represents a subdivision of the much larger Canadian Shield and forms the bedrock of portions of Ontario, Canada and the U.S. states of Michigan and Minnesota. A few significant geologic features are situated in the Southern Province, including the Midcontinent Rift System and the Sudbury Igneous Complex.
Secondary Highway 541, commonly referred to as Highway 541, was a provincially maintained secondary highway in the Canadian province of Ontario. The highway connected Highway 17 in Sudbury with the community of Skead on the southern shores of Lake Wanapitei, passing through the community of Garson en route. Within the urban region of Sudbury, the highway served to access Sudbury Airport. The designation was applied in 1956, along with many of the secondary highways in Ontario. The province transferred responsibility for the route shortly after the creation of the Regional Municipality of Sudbury in 1973. Highway 541 is now known as Sudbury Municipal Road 86, following Falconbridge Highway and Skead Road.
Secondary Highway 541A, commonly referred to as Highway 541A, was a provincially maintained secondary highway in the Canadian province of Ontario. This short 3.2-kilometre (2.0 mi) spur connected Highway 541 north of Garson with the community of Falconbridge.
The 2018 Greater Sudbury municipal election was held on October 22, 2018 to elect a mayor and 12 city councillors in Greater Sudbury, Ontario. In addition, school trustees were elected to the Rainbow District School Board, Sudbury Catholic District School Board, Conseil scolaire de district du Grand Nord de l'Ontario and Conseil scolaire de district catholique du Nouvel-Ontario.
