Kimberlites are rock formation where diamonds can be found. Diamonds form at a depth greater than 150 kilometres within the earth. After their formation, diamonds are carried to the surface of the earth by strong volcanic activity. This mixture of magma, transported rock and diamonds forms pipes...

In the 1960s, several mining companies started systematically exploring for diamonds in Canada. Today, in addition to the Ekati mine, other diamond projects could reach production within few years. This map shows the location of the main Canadian diamond exploration areas to the year 1997.

Minerals associated with diamond source rocks found in glacial sediments indicate presence of a kimberlite. To a certain extent it also gives an evaluation of the potential presence of diamonds. Regional ice advance and retreat pattern knowledge, combined with geophysical analysis, help to find...

This map shows the 815 generating stations with a capacity of 500 kilowatts or greater classed by the principal fuel used. Two fuels are dominant: water power (hydro-electricity) and petroleum products. The pattern of hydro plants across Canada is partly explained by Canada's geology: areas that...

This map shows the 815 generating stations with a capacity of 500 kilowatts or greater, classed by the type of company operating them. Most plants are operated by utilities, but nearly one-quarter of all plants are operated by other industries. All three industries identified in the map legend...

This map depicts the 77 electrical generating plants operated by forest-based industries. These industries are defined using the North American Industrial Classification. These plants are scattered throughout Canada, and are about equally divided between being hydro or thermal plants.

This map shows the 53 generating stations that were operated by companies of the mining or energy industries. The stations are often relatively large - the largest has a capacity of 912 000 kilowatts.

The 54 plants are operated by a wide variety of industries. Plants run by these industries tend to be fairly small (the largest is 38 000 kilowatts). They also tend to be found in cities. By type, these plants are a mix of hydro and thermal stations. The hydro plants tend to be older...

This map shows the 630 generating stations operated by utilities, with the stations being classed by their capacity (in kilowatts). They have an enormous size range: many are under 10 000 kilowatts, whereas a small number exceed 1 000 000 kilowatts in size.
