Surprises from the top of the mantle transition zone [PDF]
, 2016 Recent studies of chromite deposits from the mantle section of ophiolites have revealed a most unusual collection of minerals present as inclusions within the chromite. The initial discoveries were of diamonds from the Luobosa ophiolite in Tibet. Further

Chromian spinel geochemistry as a petrogenetic indicator in the chromitites and peridotites of the Bajgan Complex, Western Makran [PDF]
پترولوژیIntroductionEconomic chromite deposits are very common in ophiolite belts. These deposits usually occur in the uppermost horizons of the ophiolite mantle sequence or within the ultramafic cumulitic rocks at the base of the crustal sequence (González ...

Phlogopite and Hornblende in the Contact Metamorphosed Ultramafic Complex at Yanomine, Sangun Metamorphic Zone, Japan [PDF]
, 1999 Phlogopite and hornblende were found in amall amounts in the contact-metamorphosed dunite-harzburgite complex at Yanomine. Phlogopite occurs in interstices of silicate minerals in dunite and harzburgite located near the contact with granite.

Genesis and geotectonic setting of podiform chromitites from the Zhob Valley Ophiolite, Pakistan: inferences from chromite composition [PDF]
Episodes, 2020 Zhob valley ophiolite comprises Khanozai, Muslim Bagh, and Zhob chromitite occurrences located in Pakistan. These occurrences occur in massive, disseminated and nodular which exhibit both magmatic and deformational texture. The Muslim Bagh and Khanozai chromitites are classified into high-Cr chromitite (Cr#=0.66–0.85) while Zhob chromitite falls into ...
