Sulfide mineralization in ultramafic rocks of the Faryab ophiolite complex, southern Kerman

open access: yesJournal of Economic Geology, 2015
Introduction Worldwide, Ni-Cu and PGE magmatic sulfide deposits are confined to the lower parts of stratiform mafic and ultramafic complexes. However, ophiolite mafic and ultramafic complexes have been rarely explored for sulfide deposits despite the ...

Podiform chromite at Voskhod, Kazakhstan

open access: yes
The Voskhod podiform chromitite is one of more than 30 chromitite deposits that collectively form the Main Ore Field (MOF) within the Kempirsai Massif, in Kazakhstan. The MOF is the largest podiform chromitite ore-field in the world. The Voskhod deposit, encased in a serpentinised dunite halo, is situated within harzburgite units that comprise the ...

The recycling of chromitites in ophiolites from southwestern North America [PDF]

open access: yes
Podiform chromitites occur in mantle peridotites of the Late Triassic Puerto Nuevo Ophiolite, Baja California Sur State, Mexico. These are high-Cr chromitites [Cr# (Cr/Cr + Al atomic ratio = 0.61–0.69)] that contain a range of minor- and trace-elements ...
