Canada's mineral resources are diverse and extensive. [1] Across the Canadian Shield and in the north there are large iron, nickel, zinc, copper, gold, lead, molybdenum, and uranium reserves. Large diamond concentrations have been recently developed in the Arctic, [2] making Canada one of the world's largest producers. Throughout the Shield ...

Geologic belts of Western Canada. The geology of British Columbia is a function of its location on the leading edge of the North American continent.The mountainous physiography and the diversity of the different types and ages of rock hint at the complex geology, which is still undergoing revision despite a century of exploration and mapping.
The National Topographic System is used by Natural Resources Canada for providing general purpose topographic maps of the country. The maps provide details on landforms and terrain, lakes and rivers, forested areas, administrative zones, populated areas, roads and railways, as well as other man-made features. [ 22 ]
Map of the Mackenzie dike swarm. Ontario has many of the world's largest dike swarms. A dike swarm is a large geological structure consisting of a major group of parallel, linear, or radially oriented dikes intruded within continental crust. They consist of several to hundreds of dikes emplaced more or less at the same time during a single ...
The Western Canada Sedimentary Basin (WCSB) [1] [2] underlies 1.4 million square kilometres (540,000 sq mi) of Western Canada including southwestern Manitoba, southern Saskatchewan, Alberta, northeastern British Columbia and the southwest corner of the Northwest Territories.
The Purcell Supergroup is composed primarily of argillites, carbonate rocks, quartzites, and mafic igneous rocks of late Precambrian (Mesoproterozoic) age.It is present in an area of about 15,000 km 2 (5,800 sq mi) in southwestern Alberta and southeastern British Columbia, Canada, and it extends into the northwestern United States where it is called the Belt Supergroup.
Clearwater Lake, a lava dammed lake in the Wells Gray-Clearwater volcanic field. Based on radiocarbon and potassium-argon dating, volcanic activity in the Wells Gray-Clearwater volcanic field began in the early Pleistocene epoch, creating valley-filling and plateau-capping lava flows that have a total volume of approximately 25 km 3 (6 cu mi).
