Nigeria is within the Trans-Saharan Mobile Belt, a Pan-African orogenic belt which comprises reworked Archaean and possibly Paleoproterozoic crust and bounded to the west by the >2 Ga West African Craton and to the east and south east by the East Saharan Craton and the Congo Craton respectively.

Review of the Basement Geology and Mineral Belts of Nigeria

Nigeria is situated within the Pan African mobile belt and sandwiched between the West African Craton to the west, the Taureq Shield to the north and the Congo Craton to the southeast (Fig. 1). About half of the total area of Nigeria landmass is underlain by rocks of the Precambrian age known in the country as the Basement Complex. The remaining half is covered by Cretaceous to Quaternary ...

Chromite - Wikipedia

Chromite is found as orthocumulate lenses of chromitite in peridotite from the Earth's mantle.It also occurs in layered ultramafic intrusive rocks. In addition, it is found in metamorphic rocks such as some serpentinites. Ore deposits of chromite form as early magmatic differentiates. It is commonly associated with olivine, magnetite, serpentine, and corundum.

The typical features of podiform chromite deposits (e.g. Mosier et al. 2012; González-Jiménez et al. 2014a, b) are present in the New Caledonia chromitites. They are briefly summarized here with an emphasis on the New Caledonian characteristics. The margins of the chromitite deposits are always dunitic and may be either concordant with, or cross-cut, the lithological layering in the host ...

MAGMATIC DEPOSITS - Earth Sci

Chromite deposits are the end product of the separation of solid phases (Cr-rich spinets, (Fe, Mg) (Al, Cr. Fe) 2O4) from a liquid and their accumulation into chromite-rich layers. The processes involved in the formation of chromite layers are fractional crystallization and gravity settling. Chromite crystallizes into mineral grains within the silicate liquid and, because they are heavier than ...

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 ...

Chromite resources of Orissa are mostly confined to Sukinda ultramafic belt and Boula Nausahi igneous complex. In these deposits, chromite is mainly present as layers in ultramafic rocks (high magnesian). These high magnesian ultramafic chromite overburden rocks are dumped as waste materials during chromite mining operations. These rocks are ...
