Geology, mineralogy, ore fluid characteristics, and Ar-40/Ar-39 geochronology of the Kahang Cu-(Mo) porphyry deposit, Urumieh-Dokhtar Magmatic Arc, Central Iran

摘要

The Kahang Cu-Mo porphyry deposit is located in the middle part of the Urumieh-Dokhtar Magmatic Arc, Central Iran, and is hosted by middle to late Miocene (similar to 14 Ma) porphyritic quartz-diorite and granodiorite stocks intruded into the Eocene tuff, basaltic andesite, and andesitic flow sequences. The Miocene intrusions are calc-alkaline in composition and reflect arc-type to collisional environments (Nb/Y similar to 0.6) based on Nb-Y, Sr/Y-Y, and La/Yb-Yb discrimination diagrams.
