The aim of this work was to delineate the prospects of podiform-type chromite by staged factor analysis and geochemical mineralization prospectivity index in Balvard area, SE Iran. The stream sediment data and fault density were used as the exploration features for prospectivity modeling in the studied area. In this regard, two continuous fuzzified evidence layers were generated and integrated ...
The investigated area is a part of Sabzevar ophiolite melang of North Eastern Iran which is important from two points of view, geology and its potential of Economic Mineral deposits. The main geological units in both Chah Yabu and Cheshmeh Palang areas are serpentinized peridotite, gabbro, diabasic dykes of Upper Cretaceous and Tertiary volcanic rocks which are mainly altered. Cheshmeh Palang a...
The irregular and sporadic occurrence of chromite pods in podiform deposits (PCD), especially mountainous terranes with rough topography, necessitates finding innovative methods for reconnaissance prospecting. This research combines several remote sensing to discriminate the highly serpentinized peridotites hosting from other barren ultramafic mafic cumulates. case study is area Sabzevar Ophiol...
The chromite deposits of Aland (Barajok and Kochak villages) and Gheshlagh area in the Khoy ophiolite occur as layered, lenticular or irregular masses, surrounded by dunitie and harzburgites. These chromites are compositionally similar to alpine-type chromites, characterized by nodular, massive, disseminated and banded textures. EMPA data show that they vary widely in term of Cr-number [100Cr/C...
based on existence of the chromite deposits in the sistan and baluchestan province in iran, and also various applications of chromite in different industries, it is expected that the establishment of chromite processing plant is required in the erelong. the geographical location of a processing plant can have a strong influence on the success of an industrial venture. the processing plant site ...
No genetic link between the two main types of chromitite, stratiform and podiform chromitites, has ever been discussed. These chromitite have very different geological contexts; one is a member layered intrusions, representing fossil magma chambers, in crust, forms pod-like bodies, conduits, upper mantle. Chromite grains contain peculiar polymineralic inclusions derived from Na-bearing hydrous ...

The chromite deposits in the Neyriz area have lenticular and sometimes vein-like shape which are replaced in serpentinized dunite and harzburgite. Chromite and serpentinized olivines are major minerals and hematite and magnetite are minor minerals in the chromitic ores. Except chromite, other minerals have secondary origin that are related to serpentinization procceses. Whereas along with chr...
