Geological Formation Of Iron Ore

Geology, Prospecting and Exploration for Iron Ore Deposits ...

The largest ore concentration is found in banded sedimentary iron formations of Precambrian age. These formations constitute the bulk of iron ore resources of the world. Iron ores occur in a wide variety of geological environments in igneous, metamorphic or sedimentary rocks, or as weathering products of various primary iron bearing materials.

Banded iron formation - Wikipedia

Banded iron formations (also known as banded ironstone formations or BIFs) are distinctive units of sedimentary rock consisting of alternating layers of iron oxides and iron-poor chert. Almost all of these formations are of Precambrian age and are thought to record the oxygenation of the Earth's oceans.A typical banded iron formation consists of repeated, thin layers (a few millimeters to a few centimeters in thickness) of silver to black iron oxides, either magnetite (Fe3O4) or hematite(Fe2O3), alternating with b…

Ore genesis - Wikipedia

As they require the conjunction of specific environmental conditions to form, particular mineral deposit types tend to occupy specific geodynamic niches, therefore, this page has been organised by metal commodity. It is also possible to organise theories the other way, namely according to geological criteria of formation. Often ores of the same metal can be formed by multiple processes, and this is described here under each metal or metal complex.

Iron Ore: Sedimentary Rock - Pictures, Definition & More

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world's iron and steel industries.

1960s. The early studies concluded that the high-grade iron-ore deposits were formed during the Mesozoic, due to the downward percolation of groundwater and subsequent leaching of silica, forming enriched residual iron-ore deposits (Stubbins et al., 1961; Gross, 1968). This super-gene model for the formation of high-grade iron-ore
