Question

Discuss the different modes of acquiring the minerals

Answer 1

Economic mineral deposit types are known to occur in all geological environments. Mineral deposits have been historically classified in many different ways according to a number of geological parameters, viz., geological setting, host rocks, conceptual model, formation, etc. They are: (1) composition of the deposit (contained minerals/metals); (2) form of the deposit (size, shape, orientation, and ore mineral distribution) and tectonic setting in which the deposit occurs; (3) host rocks or geological setting (the rocks enclosing the deposit and ore associations); and (4) interpreted genesis of the deposit (geological processes, controls to form the deposit). No two mineral deposits are alike and many are known to have formed by more than one process hence classifying into a single type is difficult. Hence there is considerable change of opinion among geologists as to the exact mode of genesis of most mineral deposits. Despite varying opinion, the classification which has a genetic connotation is accepted by many.
