Peridotites, chromitites and diamonds in ophiolites

Nature Reviews Earth & Environment, 2021
Ophiolites, which represent segments of oceanic lithosphere obducted onto the continental crust, provide an important window into processes such as continental rifting, mantle melting, asthenospheric upwelling and cooling of oceanic lithosphere. Traditionally, research has focused on crustal sections of ophiolites.

Petrogenesis of ophiolitic chromitite

Geological Society, London, Special Publications, 1993
Abstract Chromite deposits comprise an integral part of the mantle sequences observed within many ophiolite complexes; in particular, those where a harzburgite is the dominant mantle sequence lithology. The chromite segregations are invariably contained within a dunite envelope and show a wide variety of ore textures, some of which are ...

Chromitites in ophiolites: How, where, when, why? Part II. The crystallization of chromitites

Lithos, 2014
Abstract A review of previous work relevant to the formation of concentrations of chromite in peridotites from ophiolitic (s.l.) sequences highlights some of the key problems in understanding the complex processes involved. This review forms the basis for chromitite-genesis models that integrate new geochemical data with petrologic, field and ...

Formation and modification of chromitites in the mantle

Lithos, 2016
Abstract Podiform chromitites have long supplied us with unrivaled information on various mantle processes, including the peridotite-magma reaction, deep-seated magmatic evolution, and mantle dynamics. The recent discovery of ultrahigh-pressure (UHP) chromitites not only sheds light on a different aspect of podiform chromitites, but also changes our ...

Advances in the understanding of chromitite deposits

Applied Earth Science, 2009
Chromitites in ophiolites and layered intrusions are the primary source of high quality chromium ore. Some chromitites can also carry significant concentrations of the platinum-group elements (PGE) and in the case of the Upper Group 2 (UG2) chromitite of the Bushveld Complex (South Africa) the PGE are the primary resource.
