Ore deposits formed in sedimentary environments

Ore deposits formed in sedimentary environments

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 and deposition.

Sedimentary Rock Structure Types Features and FAQs

Iron ore is a chemically formed sedimentary rock reproduced when Iron and Oxygen combine in a solution, leaving behind sediments that finally become Iron ore. Shale is an example of clastic sedimentary rocks that are formed out of clay-sized debris. Thereby, it is a complete layout of the formation, structure and examples of sedimentary rocks.

Iron-rich sedimentary rocks. Iron-rich sedimentary rocks are sedimentary rocks which contain 15 wt.% or more iron. Wikipedia. Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red.

Banded iron is an extinct type of chemical sedimentary rock that only formed during the Precambrian when oxygen levels were much lower than they are today. The rock is often easily identified by its alternating layers of red and gray. Banded iron formations provide much of the world's supply of iron ore, which is critical for the production of ...

iron processing - iron processing - Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is ...
