Magnetite: South Australia's potential | Energy & Mining
The iron oxide mineral magnetite as Fe 3 O 4 has a mass percent of 72.36% Fe and 27.64% O and typically occurs as a natural ore containing 15–40% Fe. Historically hematite direct shipping ore (DSO) has been the preferred source of iron ore globally, with significant resources located on several continents, including Australia in the Hamersley Range, Western Australia.

A residual origin must be discarded as the analyzed values obtained for hematite in both Horto-Baratinha and Cuité deposits do not exhibit consistent depletion of most of the mobile trace elements such as Al, Si, V, Cr, Ga, Nb, Sn, Zr and As. Ti-enrichment is associated with depletion in the Mg content, possibly due to the weak compatibility ...

The Macquarie Arc is a long-lived volcanic arc terrane which began in the latest Cambrian and continued until the early Silurian. Early Silurian high-K suites associated with Cu–Au porphyry mineralization are typically considered shoshonitic; however, comparisons with well-studied examples of shoshonites in continental arcs and associated settings suggest few Macquarie …
