The Chagai Volcanoplutonic Belt (CVB), served as the second largest magmatic arc in western Pakistan, belongs to an essential part of the Tethyan Metallogenic Domain. With the closure of the Neo Tethys Ocean, the Arabian and Indian plates collided with Eurasian plate from Late Oligocene to Miocene. Under the condition of continuous extrusion, series of thrust-folding system were formed in western Pakistan, and Pakistan experienced 4 large-scale magmatic activities: Middle-Late Eocene (43~37 Ma), Early Miocene (24~22 Ma and 18~16 Ma), Middle Miocene (13~10 Ma) and Late Miocene-Early Pliocene (6~4 Ma). And then, the CVB was formed, which developed 48 porphyry Cu-Au deposits (occurrences) or prospected area. Based on the information of regional geology and mineralization, the porphyry Cu-Au deposits in the CVB can be divided into two parts: the eastern one and western one. The former occurred in the margin of Chagai intrusion or the contact zone between Chagai intrusion and its wall rocks, and the ore-bodies developed into clastic rocks in Late Cretaceous Sinjrani Group strata and Eocene Chagai intrusion. The latter occurs within the stocks of Sor Koh intrusive rocks, which were developed in Paleocene or youngest clastic and volcanic rocks. For these porphyry deposits, the ore-bodies are associated with magnetite-series quartz diorite porphyry and granodiorite porphyry, with typically calc-alkaline in composition. Hydrothermal alteration has a clear zoning, including potassium silicate (potassic), clay, silicate sericitic, and propylitic alterations. The output characteristics of porphyry copper deposits inside and outside China show that, Sor Koh intrusion may be conform to the current situation of "little intrusion forming large deposit", and some porphyry copper deposits may be occurred within large composite batholith of Chagai intrusive rocks, so both of these intrusions have good ore-prospecting potential. The latest exploration data suggest that 48 porphyry deposits (occurrences) or prospected area maybe have very good prospecting perspective and great resource potentiality, such as Saindak, Reko Diq, Talaruk, Koh-e-Dalil and Western War Chah porphyries, especially Koh Dalil (Rackodiq) and the porphyry deposits (occurrences) or prospected area in western part of the CVB.
