Yandi Mine, Marillana Station, East Pilbara Shire, Western

The ore comes from a Tertiary pisolitic iron palaeo channel system, 80 kilometres long, incised into the shale, dolerite and banded iron formation dominated Weeli Wolli Formation, in the broad structural Yandicoogina Syncline. Most ore outcrops as low lying mesa, or is covered by up to 60 metres of colluvium and alluvium.

Oolites, Pisolites and Laterites Formation and Composition

Iron-rich laterite is mostly used as a construction stone, especially in Asia. Laterite Composition: Laterite is a residual material. It is mostly composed of iron, aluminum, titanium, and manganese oxides because these are the least soluble components of the rocks undergoing a type of chemical weathering known as laterization or lateritization.

Channel-iron deposits - Wikipedia

Channel iron deposits are iron-rich fluvial sedimentary deposits of possible Miocene age occupying meandering palaeochannels in the Early to Mid-Cenozoic Hamerlsey palaeosurface of Western Australia. Examples are also known from Kazakhstan. The deposits are anomalously high in iron for deterital material, and exclude detrital iron deposits typified by scree of hematitic banded iron formations and accumulations of currently-forming maghemite pisolite alluvials. CIDs are a major source of cheap, h

The origin of terrestrial pisoliths and pisolitic iron ore

Pisolitic iron ores (aka channel iron deposits, CID) are a special case of transported pisolitic ferricrust that form an important resource of medium grade iron ore (57–60 wt% Fe) in the Pilbara Region of Western Australia. Apart from minor deposits in the northern Yilgarn Province of Western Australia, they have not been found elsewhere.

THE IRON MINES OF GLENRAVEL by Kevin J. O’Hagan – Glens Of

In Fisher’s mines the best seams of ore yielded 60% iron and the average yield was about one ton of ore per cubic yard. Similarly, at Evishnacrow the quality was good and the peas of iron (hence pisolitic) in the ore had the appearance ‘when split, of cast steel.’ At Cargan Mines the ore was up to 40% iron falling to 18% in the poorer seams.

These rocks are usually found in the form of hematite (Fe2O3) or magnetite (Fe3O4). About 98% of world iron ore production is used to make iron in the form of steel. Nearly all of Earth’s major iron ore deposits are in rocks that formed over 1.8 billion years ago. At that time Earth’s oceans contained abundant dissolved iron and almost no dissolved oxygen.
