5 Ore deposits formed in sedimentary environments

Summary. Ore deposits form in sedimentary environments as a result of one of two generalised geological processes: either as a result of mineral precipitation from solution in surface waters, most commonly from sea water or lake waters; or as a result of physical accumulation of ore minerals during processes of sediment entrainment, transport

Geological ore deposits The Australian Museum

Geological ore deposits are of many different types and occur in all geological environments. The iron and manganese ores occur as distinct sedimentary layers alternating with iron and manganese-poor sedimentary layers the whole mass is sometimes mined. Iron ores of this type are commonly termed the banded iron formation or simply

Geology and ore genesis of the manganese ore deposits

The ore mineralization is subdivided into three different genetic types. They are classified either as pure karst deposits or as combined formations of karst origin and shallow marine sedimentation due to the transgression of the Banded Iron Formation (BIF) sea. Post-sedimentary metamorphism is identified as very low grade.

mineral deposit Iron deposits Britannica

By far the most important metal from an economic and technical point of view is iron. Sedimentary iron deposits, from which almost all iron is obtained, can therefore be viewed as one of the world’s great mineral treasures. There are two major types of deposit. The first, and by far the most important, is banded iron formations (BIFs), so called because they are finely layered
