Structures in podiform chromite from the Maqsad district (Sumail ophiolite, Oman)

Mineralium Deposita, 1985
About 15 chromite bodies have been recognized in the Maqsad area of the Oman ophiolite. The occurrence in this area of three chromite bodies within the cumulate sequence must be integrated into the classification of Cassard et al. (1981) which presently explains only those pods lying in the uppermost mantle sequence (plastically deformed harzburgites ...

Integrated geophysical surveys for searching of podiform chromite in Albania

SEG Technical Program Expanded Abstracts 1999, 1999
The geological conditions under which podiform chromite occurs are so complex and uncertain. Furthermore, the physical and chemical proprieties of chromite are such that it does not easily lend itself to the indirect prospecting methods commonly applied to other ores.

Generation of a Geochemical Model to Prospect Podiform Chromite Deposits in North of Iran

Proceedings, 2018
In regional exploration, layers of geochemical signatures play an important role for target generation of mineral deposits. In this paper, continuously-weighted geochemical signatures of podiform-type chromite deposits were first generated through a logistic-based method.

Textural Evidence for the Chromite‐Oversaturated Character of the Melt Involved in Podiform Chromitite Formation

Resource Geology, 2013
AbstractWell‐preserved oval‐shaped dunite clots occur within the exceptionally fresh massive podiform chromitites from the Coto Block of the Zambales Ophiolite Complex, the Philippines. The dunite/chromitite boundary shows an interlocking texture; olivine inclusions in chromites in the podiform chromitites show the same optical extinction with larger ...

Gravity Differentiation and Magmatic Re-emplacement of Podiform Chromite Deposits

1969
Abstract Relict cumulate features preserved in podiform chromite deposits include some textures found in stratiform complexes and, in addition, nodular and orbicular textures. Nodules of chromite are shown to have grown while freely suspended in magma, either by crystallization of chromite alone, or of chromite plus plagioclase and/or ...

Random forests algorithm in podiform chromite prospectivity mapping in Dolatabad area, SE Iran

2018
The Dolatabad area located in SE Iran is a well-endowed terrain owning several chromite mineralized zones. These chromite ore bodies are all hosted in a colored melange complex zone comprising harzburgite, dunite, and pyroxenite. These deposits are irregular in shape, and are distributed as small lenses along colored melange zones. The area has a great
