Iron oxide copper-gold (IOCG) deposits

Hitzman et al. (1992) included a number of other iron oxide-rich deposits in first defining the 'Proterozoic iron oxide (Cu-U-Au-REE)' class of ore deposits, and proposed a preliminary model involving extensional tectonic settings. Subsequently, a large number of highly diverse deposits, some newly discovered and others re-classified, have ...

Iron

Properties. In the Earth's crust iron is found mainly as minerals of iron oxide such as hematite, magnetite, goethite and limonite. The minerals that are mostly used as ore for making iron are hematite (Fe 2 O 3) and magnetite (Fe 3 O 4).Iron is quite soft and easily worked, but it has a very high melting point of 1538°C.
