Mineral resources in Canada
Minerals are naturally found in Earth's crust. These are inorganic compounds, unlike fossil fuels, like oil, coal, and gas. These are not derived from plant or animal matter i.e they are inorganic compounds. These compounds structures an outstanding portion of Earth’s crust. Canada has a variety of natural resources and leads in production of potash, uranium, and salt, uranium, and many more.
Investments:
The mineral industry of Canada is mainly export oriented, with the US being it’s main commercial partner. The main and important factor that helps in expansion of the industry is it’s easy access tomorrow markets of chin, Japan , Europe, and North America. In 2010 alone, Canada attracted 19% of world's expansion spending. Canadian mineral industry attracts around $50 billion in capital investment annually.
Regional distribution:
It has six major geological regions, with different resources.
Canadian shield: It underlies about half of the total area of Canada. It is made up of precambrian rock. The most vast distribution of ancient precambrian igneous, metamorphic and sedimentary rocks , glacial overburden, forest and muskeg are Canada’s leading source of precious and heavy metals. It has large amounts gold, uranium and iron ore.
Canadian cordillera: It is present into the west of interior plains. It is mountainous and valleys with various igneous and sedimentary rocks. It has extensive and varied mineral resources. The western and central parts of cordillera contain a variety of metals such as gold, silver, lead, copper, iron ,zinc. Eastern region has deposit of fossil fuels, namely coal and natural gas.
Interior platform: Between the Canadian shield and the cordilleran mountains region of western Canada , and street ting from US border to Arctic ocean lies Interior platform. It includes Arctic platform, the interior plains, the Hudson bay lowlands and St. Lawrence platform, mineral resources forums here are potash and salt, oil, natural gas and coal. Lately, the extraction of bitumen. And oil sands has been increased fastly. The Hudson bay lowlands stretch through northern Ontario and northeastern mantoba. It is geographically characterised by volcanic and sedimentary rocks and contain deposit of copper, zinc, gold, nickel.
Appalachian orogen: it is located southeast of the shield, consist of broad belt of mountains, hills, and plains. A great variety of minerals are found here mainly asbestos, zinc and lead. Gypsum formation , potash and salt deposits are found all over the region .
Innuitian orogen: it lies in Arctic archipelago. Minerals including salt, rock salt, and gypsum has also been found in the region.
Resource: Uranium
Canada is the second largest producer in the world . The majority of Canada’s uranium resources are in high grade deposits, some 100 times the world average . Many of these have difficult mining condition which require ground freezing.
Properties:
It is a hard, dense, malleable, ductile, silver white, radioactive metal with high density. It can react with cold water, when finely cut . It is coated with uranium oxide on contact with air which rapidly tarnishes. Uranium gained importance with development of practical uses of nuclear energy. In modern era, it has a great significance in nuclear power plants due to its radioactive properties . Depleted uranium is used as shielding to protect tanks, and also in bullets and missiles. In environment, it is not particularly rare. In air, the concentration are very low. Even when at higher than usual concentration in air , there is so little uranium present per cubic metre that less than one...
