Chromite in the Oman ophiolite is located in the mantle section of the ophiolite sequence and forms abundant small podiform deposits throughout the length of the ophiolite (Rollinson, 2005). The Oman ophiolite has an exposed mantle section of ca 10 000 km2, and contains ca 200 chromitite bodies.

The chromite ore Cr/Fe ratio is of importance as it directly affects the alloy Cr grade whilst the gangue elements affect the melting energy and rate as well as the slag chemistry. The chromite spinel ore morphology can be described stoichiometrically as (Fe, Mg)(Cr,Al,Fe)2O4 and chromite ores often contain gangue elements of SiO2 and MgO.

The composition of the interstitial silicates is comparable to that found in early cumulates. Type-1 and type-2 chromite deposits crystallized from a magma similar to that from which the basal cumulates formed (Al 2 O 3, 15.1–16.1 wt%; FeO/MgO, 0.55–0.60).

Although Oman is the largest and best exposed ophiolite in the world, it seems to be comparatively poor in chromite due to the spreading situation. In the Lherzolite Ophiolite Type (LOT), thought to be derived from slow spreading ridges, the chromite deposits are absent as a result of chromium being retained in mantle diopside during partial ...

Magnesium oxide (Mg O), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide).It has an empirical formula of Mg O and consists of a lattice of Mg 2+ ions and O 2− ions held together by ionic bonding. Magnesium hydroxide forms in the presence of water (MgO + H 2 O → Mg(OH) 2), but it can be reversed by heating it ...

The mountains of Oman are rich in mineral deposits. Copper ore is being mined in the northern Oman. The ore is processed into electrolytically refined copper cathodes for export. Gold and silver are produced as by-products for export. The Sultanate has also started mining chromite and exporting since early 80’s.

Chromite deposits in the northern Oman ophiolitic complex occur in three structural contexts, i.e., (1) at the base of the cumulate series, (2) in the top kilometer of the mantle sequence, and (3) in the deeper parts of the mantle. Types 1 and 2 are characterized by the diversity of interstitial silicates where in decreasing order of abundance olivine, clinopyroxene, orthopyroxene, plagioclase ...
