    About 90 per cent of the pre-mining BIF-hosted iron ore resource of the Hamersley Province of Western Australia is of the Phanerozoic supergene martite-goethite type. The remaining ten per cent formed as supergene deposits at 2000 200 Ma, and were later modified by burial to form the Proterozoic martite-microplaty hematite ores. The supergene-metamorphic segment...

    The iron deposits in the Anshan-Benxi, eastern Hebei, Wuyang, and Huoqiu iron ore clusters, located in or in the periphery of the North China Craton, belong to Anshan-subtype of BIF-related sedimentarymetamorphic iron deposits. The iron deposits in the western Shandong iron ore cluster are Anshan and Laiwu skarn subtypes.

The uplifting of the metamorphic massif and related post-metamorphic tectonics possibly in Neo-tectonic period gave way the prominent channels for emplacement of hydrothermal fluids in the area.

    Iron Ore Formation. Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without ...

    The iron ore is massive coarse-grained hematite-magnetite rock in a folded layer, 30 meters thick, in Precambrian gneiss. Mineralogic, textural, structural, and oxygen isotope data indicate that the hard ore represents a pre-metamorphic concentration of iron that was later deformed and metamorphosed, rather than a concentration during metamorphism.
