Quizplus · Accepted Answer

Placer deposits form when erosion produces clasts of native metals, which are then transported and deposited by water in sedimentary environments. Secondary-enrichment deposits are formed when groundwater or weathering processes dissolve and redeposit metal minerals within an existing ore deposit. Mississippi Valley-type deposits are formed by the circulation of metals and brines through a sedimentary basin, and magmatic deposits are formed by the cooling and crystallization of magma.
