Podiform Chromite Deposits--Database and Grade and Tonnage ...

15.08.2012 · We have identified 1,124 individual podiform chromite deposits, based on a 100-meter spatial rule, and have compiled them in a database. Of these, 619 deposits have been used to create three new grade and tonnage models for podiform chromite deposits. The major podiform chromite model has a median tonnage of 11,000 metric tons and a mean

19.07.2021 · Ophiolitic ultramafic rocks are the hosts of podiform chromite deposits. Podiform chromite deposits are small magmatic chromite bodies formed in the lower level of an ophiolite complex. Podiform chromite mines have produced 57.4% of the world’s total chromite production . Ophiolite zones in Iran are widespread and are often found in different locations

A desirable guide for estimating the number of undiscovered mineral deposits is the number of known deposits per unit area from another well-explored permissive terrain. An analysis of the distribution of 805 podiform chromite deposits among ultramafic rocks in 12 subareas of Oregon and 27 counties of California is used to examine and extend this guide. The average

Chromite deposits occur in both complexes. They are highly sheared in the Gomati complex but grade to host dunite in the Vavdos complex. Major oxide contents and trace element abundances have been determined by X-ray fluorescence spectrometry, mineral analyses have been made by electron microprobe. Data on chromite from both complexes reveal that the chromite ores

MAGMATIC DEPOSITS - Earth Sci

Podiform. Stratiform chromite deposits consist of laterally persistent chromite-rich layers (a few mm to several m thick) alternating with silicate layers. The silicate layers include ultramafic and mafic rocks such as dunite, peridotite, pyroxenite and a variety of others, less commonly gabbroic rocks. They are generally found within basal portions of mafic-ultramafic layered intrusions of ...

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

Magmatic chromite deposits (chromitites) are the main source of chromium for industrial use, and, in some cases, they may carry variable amounts of accessory metals (Ni, Cu, Au, and platinum-group elements) which may have a great economic interest as byproduct of chromium extraction. Exceptionally, some chromite deposits have become a major source of precious
