Introduction. Western Australia is a major source of the world's iron ore resources, held within three main provinces – the Hamersley Basin (44962 Mt of iron resources plus reserves at cut-off values >40 wt% Fe total; MINEDEX database), Yilgarn Craton (7181 Mt), and the Pilbara Craton (6401 Mt).The Yilgarn Craton hosts Archean, Algoma-type, banded iron …

High-grade hematite ores in the Hamersley Province of Western Australia are associated with hydrothermal magnetite-apatite and magnetite-hematite-carbonate-apatite proto-ores below the modern weathering surface. In addition, hydrothermal alteration of country rocks, once believed to be absent, is now recognised widely in shales and dolerites up to several …
The Wiluna West small (~ 130 Mt) high-grade bedded hematite ore deposits, consisting of anhedral hematite mesobands interbedded with porous layers of acicular hematite, show similar textural and mineralogical properties to the premium high-grade low-phosphorous direct-shipping ore from Pilbara sites such as Mt Tom Price, Mt Whaleback, etc., in the …

Banded iron formation (BIF)-hosted iron ore deposits in the Windarling Range are located in the lower greenstone succession of the Marda–Diemals greenstone belt, Southern Cross domain, Yilgarn Craton and constitute a total hematite–martite–goethite ore resource of minimum 52 Mt at 60 wt.% Fe (0.07 P). Banded iron formation is interlayered with high-Mg …
The Eastern Goldfields Province of the Archean Yilgarn Craton, Western Australia (Fig. 1), is host to numerous gold deposits (Groves et al. 1992; Witt and Vanderhor 1998; Hagemann and Cassidy 2001). The Kalgoorlie district is the largest in the region and includes the giant Golden Mile (production 1,435 ton Au) and the Mt Charlotte (125 ton Au ...

Sir: We have read with interest the paper of Taylor et al. (2001), which suggests a new genesis for the hematite deposits of the Hamersley province via an intermediate hypogene carbonate-rich phase structurally controlled by high-angle normal faults (e.g., Southern Batter fault at Tom Price). In attempting to apply their genetic model to the Mount Whaleback deposit, they have invoked …

The western Yilgarn Craton consists of extensive Archean granite–greenstone terrain and high-grade gneisses that contain significant deposits of gold, iron ore, nickel, copper, lead, zinc, tungsten, molybdenum, bismuth, vanadium, titanium, beryllium, lithium, tin, tantalum and uranium — with clear potential for the discovery of more ...
The Joyner's Find greenstone belt (JFGB) containing the Wiluna West iron ore deposit is situated on the northern margin of the Yilgarn Craton, 30 km west of the town of Wiluna and about 700 km northeast of Perth in Western Australia (Fig. 1 A).The Neoarchean JFGB trends in a southerly direction from the north-eastern margin of the Yilgarn craton beneath the …

The Hamersley province of northwest Western Australia is one of the world's premier iron ore regions.

The Hamersley Province of Western Australia (Fig. 1) contains numerous economic deposits of iron ore where millimetre to centimetre scale magnetite and chert layers of Proterozoic banded iron-formation (BIF) have been converted to oxidized iron minerals (Harmsworth et al., 1990).Collectively, these deposits produce approximately 100 Mt/year of …
Structure is the most important control on the location of hematite deposits in the Hamersley Province in the Pilbara region of Western Australia. Unravelling the structural history of mineralised areas, however, is complex because the Province underwent three orogenic events, and three regional extension events followed the main episodes of compression. Steeply E to …
