Banded Iron Formation
BIF-hosted iron ore deposits can be divided into three classes on the basis of their iron content: (1) iron-rich primary BIFs containing 30–45 wt.% Fe, (2) high-grade martite-goethite ores with 56–63 wt.% Fe, and (3) high-grade hematite ores containing 60–68 wt.% Fe (Clout and Simonson 2005). The bulk of iron ore mined today corresponds ...

Smaller, more shallow hematite mineralisation appears to occur below the basalt thrust of the Seyala Formation. This mineralisation appears to cross cut stratigraphy and is interpreted to be hydrothermal in origin, with formation of specularite hematite as well as microplaty hematite along fractures.
