Essentials of Mineral Exploration and Evaluation ...

Ore deposits are crustal concentrations of useful elements that can be exploited at a profit. The basic requirements for any ore deposit to form are described. Classification of ore deposits based on (1) composition, (2) form of deposit, (3) associated host rocks and geological structures, and (4) interpreted genesis is described.
