Lithogeochemistry & Alteration at Serenu Porphyry Copper Occurrence, Northwest of Shahr-e-Babak, With Special Reference to Fluid Inclusions

Serenu porphyry copper occurrence is located northwest of Shahr-e-Babak, in southern part of Orumieh-Dokhtar volcano-plutonic belt. Eocene volcanics and pyroclastics are the oldest geological units in the area. Oligo-Miocene diorite and quartzdiorite and Neogene dacite and andesite intruded the volcanics. Mineralized diorite and quartz diorite porphyries have emplaced along the main E-W trend fault system of the Serenu area. The alteration types are phyllic, argillic, propylitic and minor biotitization (weak potassic). The mineralization occurs as malachite, pyrite and chalcopyrite. Geochemical characteristics for the formation of the occurrence were determined through fluid inclusion studies. Moreover, using geostatistical data, the
