The Meiduk porphyry copper deposit is located in the northwest of Dehaj- Sarduieh volcano- sedimentary complex in Kerman (southeast of Urumieh- Dokhtar volcano-plutonic belt) and about 42 Km northeast of the Shahr-Babak. The Meiduk porphyry stock with an age 12.5 Ma intruted into Eocene volcanic rocks with andesite, andesitic-basalt and dacite composition (Razak complex). Petrographic studies indicate that this deposit consists mainly of diorite, q-diorite and granodiorit rocks. Mineralogically, Meiduk porphyry rocks contain plagioclase, K-feldespar amphibole, biotite and quartz. Sericite, cholerite, epidote and magnetite are secondry phases. Geochemically, the Meiduk porphyry rocks are alkali and alkali- calcic, meta to peralumine and I-type granitoids. Tectonic studies indicate that the Meiduk porphyry were emplaced at active continental margine. Tectonic characteristics also indicate that, after the collision of the Arabian and Iranian plates, the Meiduk porphyry was emplaced during a late orogenic stage of arc development (compressional tectonic regimes) in a post-collisional tectonic setting at the end of magmatism related to Neo-Tethyan subduction system.
