2.14: Energy and Resources- Metal Deposits

A magmatic deposit is one in which the metal concentration takes place primarily at the same time as the formation and emplacement of the magma. Most of the nickel mined in the world, and much of the copper, comes from magmatic deposits such as those in Indonesia, Canada, southern Africa, Australia and Siberia (Figure 8.1.2).
