Generally, metallic minerals are found in igneous and metamorphic rock formations that form large plateaus.

Explanation:

Iron-ore in north Sweden, copper and nickel deposits in Ontario, Canada, iron, nickel, chromites and platinum in South Africa are examples of minerals found in igneous and metamorphic rocks.

Answer 2

Answer:

The dense sulphide magma that contains the metals is then forced by gravity to accumulate close to the silicate magma base, and both magmas cool down and crystallize, forming rocks. If all of these processes go efficiently, a profitable nickel sulphide and copper deposit is formed.
