The Chalukou Mo deposit was formed in a continental arc at ca. 150 Ma. The barren magmas were originated mainly from partial melting of juvenile crust, whereas the ore-causative granites require additional involvement of old continental crust. The deposit was the product of the southeastward subduction of the Mongol–Okhotsk oceanic plate.
