The Yilgarn Craton is a large craton that constitutes the bulk of the Western Australian land mass. It is bounded by a mixture of sedimentary basins and Proterozoic fold and thrust belts. Zircon grains in the Jack Hills, Narryer Terrane have been dated at ~4.27 Ga, with one detrital zircon dated as old as 4.4 Ga.. The Murchinson Province of the craton contains the oldest dated meteorite impact .
Channel iron deposits are an important source of iron ore, with the deposits at Yandi and Robe River accounting for approximately 47% of iron ore mined from the Hamerley Iron province. Although channel iron deposits are typically low-grade at 53% to 57% Fe in-situ, they are composed of goethite-limonite which are hydrated iron oxide species.
Microplaty hematite ore in the Yilgarn Province of Western Australia: The geology and genesis of the Wiluna West iron ore deposits. / Lascelles, Des; Tsiokos, D.S. In: Ore Geology Reviews, Vol. 66, 2015, p. 309-333. Research output: Contribution to journal › Article
The Hamersley province of northwest Western Australia is one of the world's premier iron ore regions. The high-grade iron ore deposits are mostly hosted within banded iron formation (BIF) sequences of the Brockman and Marra Mamba Iron Formations of the Hamersley Group and consist of two types: martite-microplaty hematite containing between 60 and 68 wt percent Fe, and martite-goethite .
More convincing are those, such as the specular, coarse, platy, micaceous or bladed hematite con• centrations with magnetite, in vertical pipe-like folds affecting supergene ore at Koolyanobbing (Yilgarn Block, Western Aus• tralia).
The Iron Ore Projects are situated in the Yilgarn Region of south-western, Western Australia. The Yilgarn Region is a host to many significant mineral deposits that have been or are being mined for iron ore. The tenements cover the Yeriligee greenstone belt which is some 80 km in length and lies within the Southern Cross Province of the Yilgarn.

The Hamersley Province of Western Australia 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 iron ore, or 10% of the world's total iron ore production .
Radar Ironreports near-surface RC drilling at its Johnston Range and Evanston iron ore project areas in Western Australia's Yilgarn region confirmed the potential for hematite mineralisation. The best result of 77 holes drilled for 6003m was 24m @ 57.4% Fe. More .
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 Hamersley Province and Goldsworthy, Shay .
Abstract. 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 .
Gold deposits in ferruginous gravels and duricrust are typically small (<500,000 ounces) and of low grade (<1–5 g/t Au; Fig. 1 Type C; Table 1).They are near-surface and occur as flat lying zones (2–10 m thick) of Au enrichment within the upper ferruginous zone of lateritic profiles and are easily mined (Galloway Warland and Phang, 2000, Paine et al., 2000, Anand, 2000, Anand et al., 2017).
The association says the central Yilgarn, centred about 150km northeast of Kalgoorlie, has estimated potential reserves of 10 billion tonnes of magnetite and a billion tonnes of hematite. It believes greater co-operation among the region's producers and explorers could fast-track the development of several mines.
In situ SHRIMP U–Pb dating of magmatic zirconolite (CaZrTi2O7) in the Golden Mile Dolerite from the Mt Charlotte gold deposit (Yilgarn Craton, Australia) has yielded the first robust emplacement age (2,680 ± 9 Ma) for the principle host-rock of gold mineralization in the Kalgoorlie district. In contrast, co-magmatic zircon gave ages from ~2.68 Ga to ~2.17 Ga, reflecting isotopic resetting .

The channel iron deposits (CID) mined in the Hamersley Province account for up to 40% of the total iron ore mined from the Hamersley Province of Western Australia. These deposits are of Miocene age and occupy meandering palaeochannels in a mature surface .
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 basalts at Windarling and .
Jul 31, 2012 · The ~2,752-Ma Weld Range greenstone belt in the Yilgarn Craton of Western Australia hosts several Fe ore deposits that provide insights into the role of early hypogene fluids in the formation of high-grade (>55 wt% Fe) magnetite-rich ore in banded iron formation (BIF). The 1.5-km-long Beebyn orebody comprises a series of steeply dipping, discontinuous, <50-m-thick lenses of magnetite .
