Mineral deposit - Iron deposits | Britannica

Mineral deposit - Mineral deposit - Iron deposits: By far the most important metal from an economic and technical point of view is iron. Sedimentary iron deposits, from which almost all iron is obtained, can therefore be viewed as one of the world’s great mineral treasures. There are two major types of deposit. The first, and by far the most important, is banded iron

Iron Formation: The Sedimentary Product of a

Iron formations are economically important sedimentary rocks that are most common in Precambrian sedimentary successions. Although many aspects of their origin remain unresolved, it is widely accepted that secular changes in the style of their deposition are linked to environmental and geochemical evolution of Earth.

Geological Controls on High-Grade Iron Ores from

Numerous iron ore deposits are hosted within the Meso to Neo-Archean banded iron formations (BIFs) extending across the Singhbhum-Orissa Craton, eastern India. Despite the widespread distribution of BIFs, which forms part of the iron ore group (IOG), heterogeneity in their grade and mineral composition is occasionally observed even within a single ore deposit.

Ore Deposits Formed by Sedimentation

Materials of sedimentary deposits have been derived chiefly from: 1) weathering of rocks. 2) weathering and oxidation of former mineral deposits viz., iron, manganese, copper. 3) some material constituting sedimentary deposits may have passed through an intermediate organic stage. The earth’s crust contains on average 5.6% Fe.

The role of siderite in Phanerozoic and Precambrian iron formations is discussed. Various types of iron formations are characterized, and their place in the evolution of sedimentary iron ore deposition is outlined. In Precambrian iron ore deposition, siderite is a primary mineral, whereas in Phanerozoic iron formations it becomes a secondary mineral and is commonly related to diagenetic and ...
