Kuruman Iron Formation Mining

The structural/stratigraphic development of the Sishen

18/07/2013· The mineralisation process is related to regional scale supergene iron enrichment of Kuruman banded iron formations along the unconformity. During regional tectonism associated with the Kheis orogeny (2400–1700 Ma) the Maremane dome was uplifted, and the basal dolomite units thus exposed to erosion and karstification.

Ironstones and iron formations | SpringerLink

Iron-rich sedimentary rocks contain ≥15 percent metallic iron by weight (James, 1966) and form a class of chemical sediments comparable to evaporites and phosphorites.Most workers recognize two main categories. Iron Formations are generally cherty, thinly laminated, and Precambrian in age.Ironstones are generally less siliceous, more aluminous, not laminated, smaller, and Phanerozoic in age.
