Abstract
Songpan-Motianlin mineralizing belt is located in the juncture area of Sichuan,Shaanxi and Gansu provinces.Yangshan gold deposit is a superlarge deposit found in the belt.The deposit is controlled by magmatic rocks and strata besides structures,and belongs to hypabyssal epithermal alteration rock type.Next step ore prospecting in the area will be focused on grade Ⅰto grade Ⅱthen grade Ⅲ perspective regions to find hopeful targets using synthesis prospecting methods of geophysics,geochemistry and remote sensing.Train of thought for ore prospecting is mainly concentrated on ore type,a priority order is structure-controlled alteration rock,micro-disseminated and quartz vein types.Ore prospecting will be strengthened in the Anchanghe-Guanyinba main structure alteration belt,particularly in the both sides and depth of the belt.
