The Cretaceous limestones in western parts of NW of Yazd are hosted by skarn - marble mineralization. The skarns are distal type and are characterized by assemblage: Clinopyroxene, garnet, ...

New investigations are carried out on the mineralogy and mineral chemistry of sulfide assemblages obtained in samples from one core in the hydrothermally active, southwest basin of the Atlantis II deep, Red Sea. The most abundant sulfide phases are the exsolved intermediate solid solution (ISS) and chalcopyrite. Sphalerite, pyrrhotite, marcasite, mackinawite, and presumably wurtzite are also ...
