60 kilometres north-west of Tom Price Mine, West Australia
The Pilbara region is located in the northwest of Western Australia, approximately 1,100km north of Perth. The region contains the 80,000 square km Hamersley Iron Province. The geology of the Province is characterized by a 2,500 million years old group of late Archaean and early Proterozoic rock formations known as the “Hamersley Groupâ€.
The Hamersley Group was formed by chemical sedimentation of minerals in a marine (ocean) environment. The processes which formed the Hamersley Group occurred after volcanic activity introduced basalt rocks in the area. Sedimentary rocks like sandstones also occur in the group due to weathering and transportation of rocks which occurred during the period when the Hamersley Group was formed.
The Hamersley Group is approximately 2.5km thick. It contains several large units of Banded Iron Formation (BIF): rock with bands of iron minerals (magnetite and hematite) and gangue minerals (mostly carbonates, silicates and chert). Typically, unenriched BIF contains about 30 per cent iron by weight.
The BIF layers have been deformed by geological processes, and eroded by weathering resulting in the geological formations that we see today.
In the Pilbara, other types of ore deposit exist, notably channel iron deposits, but these are derived from the original bedded iron formations.
