Reference information

Comments Average grade of 0.07% Mo. Occurrence, large from Nokleberg and others (2006). Associated with granite-granodiorite and leucogranite intrusions. Gangue minerals are quartz, feldspar, sericite, and carbonate. Consists of a Cu-Mo stockwork hosted in Proterozoic schist and gneiss intruded by a Paleozoic granitoid stock. The host rocks are altered to K-feldspar, silica, and sericite. A hydrothermal alteration zone contains some intensely brecciated and silicified areas.
Study area name Central Asian Orogenic Belt
