Origin of podiform chromitites

Journal of Asian Earth Sciences, 1997
Abstract Podiform chromitite with a dunite envelope can be interpreted to be a product ofinteraction between mantle harzburgite and an exotic magma, combined with magma mixing. The secondary Si- and Cr-rich melt which is produced by the selective dissolution of orthopyroxene can be mixed with a subsequently supplied primitive melt with the mixed melt

Intermediate chromitite in Kızıldağ ophiolite (SE Turkey) formed during subduction initiation in Neo-Tethys

Ore Geology Reviews, 2019
Chromitites in the Kizildag ophiolite mostly occur in the mantle harzburgites and some of them in crustal cumulate dunites. Olivine in both the dunites and chromitites is highly magnesian (Fo = 90.5–92.8 and 90.2–96.1, respectively), while the coexisting

Podiform chromitite in the arc mantle: chromitite xenoliths from the Takashima alkali basalt, Southwest Japan arc

Mineralium Deposita, 1994
Chromitite xenoliths from the Takashima alkali basalt in the Southwest Japan arc are classified into two types: Type 1 chromitite in thin layers in dunite or wehrlite xenoliths; and Type 2 chromitite in discrete xenoliths which has an orbicular texture, previously documented only from podiform chromitites in ophiolites.

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.

The Kemi stratiform chromitite deposit, northern Finland

Economic Geology, 1989
The Kemi chromite deposit is hosted by an early Proterozoic (2.44 Ga) layered intrusion. The lower part of the intrusion is composed of peridotitic and pyroxenitic cumulates and chromitite layers. Olivine and chromite have not been observed in the upper part, where plagioclase is the predominant cumulus phase occurring either alone or together with ...

A reappraisal of the metamorphic history of the Tehuitzingo chromitite, Puebla state, Mexico

Soviet Economy, 2018
The Tehuitzingo ultramafic body (Acatlán Complex, southern Mexico) is a strongly serpentinized harburgitic body that encloses chromitite bodies and blocks of eclogitic rocks.

Chemical variations of mineral inclusions in Neoproterozoic high-Cr chromitites from Egypt: Evidence of fluids during chromitite genesis

Lithos, 2016
Abstract This paper details the mode of occurrence, petrography, and chemistry of mineral inclusions hosted in chromian spinels of the Neoproterozoic chromitites in the Southern Eastern Desert of Egypt. Neoproterozoic podiform chromitites from the Arais, Balamhindit, and Abu Dahr areas, in the Southern Eastern Desert, can be texturally and chemically

Geochemistry of the chromitite stringer at the contact of the mafic sequence and the ultramafic sequence in the Unki Mine area, Shurugwi Subchamber of the Great Dyke, Zimbabwe

, 2020
Several models have been proposed to explain the origin of a chromitite stringer located at the contact between the Mafic and Ultramafic Sequences in the Unki Mine area of the Shurugwi Subchamber of the Great Dyke, Zimbabwe.
