Genesis of Podiform Chromite Deposits——Evidence from the Luobosa Chromite Deposits, Tibet

Acta Geologica Sinica-English, 1987
Abstract Taking for example the Luobosa chromite deposit in Tibet combined with other deposits of the same type in the world, the paper discusses the genetic mechanism of podiform chromite deposits. The study indicates that chromite and dunite‐harzburgite are both the products of different degrees of partial melting of the same primary pyrolite (spinel

Integrated Geophysical Surveys for Searching of Podiform Chromite in Albania

4th International Congress of the Brazilian Geophysical Society, 1995
The purpose of this paper is to describe the application of geophysical methods to the search for chromite in Albania. Albania is well known for its chromite resources and ranks third amongst world producers of high-quality chromite. The ultramafic massif of Bulqiza, is the most important chromite bearing one.

Primitive basaltic melts included in podiform chromites from the Oman Ophiolite

Earth and Planetary Science Letters, 1997
Abstract In an attempt to characterize the composition of the parental melts of ophiolitic chromitites and their tectonic setting, we have undertaken a study of polymineralic solid inclusions trapped in chromites from the Oman Ophiolite (Sumail nappe).

Characteristics and implications of podiform-chromite hosted silicate inclusions in the Zedang ophiolite, Southern Tibet

Lithos, 2021
Abstract The Zedang ophiolite, containing pods of massive chromitite, crops out in the eastern segment of the Yarlung-Zangbo suture zone, Southern Tibet. Chromite grains in the Zedang chromitite bodies have high Cr# [Cr/(Cr + Al)] (0.73–0.82) and Mg# [Mg/(Mg + Fe)] (0.73–0.79), and low TiO2 content (0.13–0.25 wt%); they contain diopside (Di ...

Conditional estimates of the number of podiform chromite deposits

Nonrenewable Resources, 1994
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.

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.
