Magmatic Evolution at the Saindak Cu-Au Deposit: Implications for the Formation of Giant Porphyry Deposits

The Chagai porphyry copper belt is a major component of the Tethyan metallogenic domain, which spans approximately 300 km and hosts several giant porphyry copper deposits. The tectonic setting, whether subduction-related or post-collisional, and the deep

Systematization of u-pb zircon ages of granitoids from the copper porphyry deposits on the urals

Литосфера, 2017
There is a generalization of U-Pb age of zircons from the copper-porphyry deposits of the eastern slope of the Urals. Approved reserves of the largest ones are about 1.4-1.8 Mt of Cu (at an average content of 0.4-0.6 wt % of Cu).
