Question

Quizplus · Accepted Answer

Commercial ore deposits are most often associated with igneous rocks, particularly mafic and ultramafic rocks. These rocks have a high concentration of minerals that are often economically valuable, such as copper, nickel, and platinum. Basinal sandstones and shales may host oil and gas deposits, while blueschists and evaporite sequences are less likely to host economically viable ore deposits.
