The geology and exploration potential of the Liwu-type copper-rich deposits in western Sichuan

The Jianglang dome located in western Sichuan is famous for the occurrence of the Liwu-type copper-rich deposits. Referenced to the previous data, the present paper focuses on the geological characteristics and exploration potential of the Liwu-type copper-rich deposits. The Liwu Group Complex within the Jianglang dome is interpreted to be the sources of the ore-forming matter enough for the formation of the copper-rich deposits. The brittle and ductile deformations caused by ductile shear zones and gravity slipping may be considered to be favourable structural conditions for the mineralization of the copper-rich deposits. The Yanshanian granites may contribute to the thermodynamic sources and partial ore-forming fluids for the mineralization of the copper-rich deposits. The potential exploration areas are delineated in the Boxianglin-Wajingou-Zhongzui-Sunyelin zone in the north and the Heiliudong-Liwu zone in the south of the Jianglang dome.
