Origin of podiform chromite deposits by magma mingling

Earth and Planetary Science Letters, 1998
Abstract I have oversaturated the immiscible system SiO2 Al2O3 FeO K2O with FeCr2O4 to study the fractionation of chromite between conjugate siliceous and fayalitic melts. Although both melts are oversaturated with chromite, chromite only nucleates in the fayalite-rich melt where the crystal/melt interfacial energy (γSL) is lowest. In less than three

Trace Elements in Chromite as Indicators of the Origin of the Giant Podiform Chromite Deposit at Kempirsai, Kazakhstan

Economic Geology, 2022
Abstract This study presents a complete trace element data set of chromite from the world’s largest podiform chromite deposit at Kempirsai, Kazakhstan, together with platinum group element (PGE) and Re-Os isotope compositions, to explore the potential of trace elements in the study of podiform chromite deposits.

A hypothesis of origin for podiform chromite deposits

Geochimica Et Cosmochimica Acta, 1975
Podiform chromite deposits are lenticular, chromite-rich autoliths in deformed dun-ites and harzburgites of ophiolite complexes. The ophiolite association is assumed to be created along accreting plate boundaries in the oceanic lithosphere. It is suggested that podiform chromite deposits form as magmatic cumulates in elongate magma pockets along the ...

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 ...

Genetic Link between Podiform Chromitites in the Mantle and Stratiform Chromitites in the Crust: A Hypothesis

Minerals (Basel, Switzerland), 2021
No genetic link between the two main types of chromitite, stratiform and podiform chromitites, has ever been discussed. These two types of chromitite have very different geological contexts; the stratiform one is a member of layered intrusions ...

Application of Satellite Remote Sensing, UAV-Geological Mapping, and Machine Learning Methods in the Exploration of Podiform Chromite Deposits

Minerals (Basel, Switzerland), 2023
The irregular and sporadic occurrence of chromite pods in podiform chromite deposits (PCD), especially in mountainous terranes with rough topography, necessitates finding innovative methods for reconnaissance and prospecting.

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
