The Kuhshah ultramafic complex is located in the south-east of Sanandaj-Sirjan metamorphic zone, near the probable remnants of Neotethys plate in Iran. It consists of highly depleted harzburgites, dunites, chromitite bands and altered gabbros. The ultramafic parts have been intruded by numerous clinopyroxenite dykes and veins. In the harzburgites, there are different generations of olivine, ort...

The podiform chromitite deposits of the Ordovician Sorkhband ultramafic complex, southwestern Makran, are the largest chromitite deposits in Iran. The Sorkhband ultramafic complex comprises of a northern part of dunite, podiform chromitite, olivine clinopyroxenite, wehrlite and olivine websterite and a southern part of foliated diopsidic harzburgite with subordinate dunite, olivine clinopyroxen...

MIL 03346 is a newly discovered meteorite from Miller Range in Antarctica, which belongs to the nakhlite group of Martian meteorites [1]. It is an unbrecciated, mediumgrained olivinebearing clinopyroxenite with a cumulate texture, similar to the 6 other previously known nakhlites. This is only the 2 nakhlite in Antarctic collections, the other being Yamato 000593 and its pairs. The Meteorite Wo...

Subduction of oceanic crust buries an average thickness 300–500 m sediment that eventually dehydrates or partially melts. Progressive release fluid/melt metasomatizes the fore-arc mantle, forming serpentinite at low temperatures and phlogopite-bearing pyroxenite where slab surface reaches 700–900 °C. This is sufficiently high to melt subducted sediments before they approach depths arc magmas ar...
