Gold Metallogenic Geological Characteristics and Prospect Analysis for Xuejiaya Gold Deposit in Shimian of Sichuan

Xuejiaya gold mine in Shimian of Sichuan is located in the secondary Xiyoufang shear belt of Daduhe shear belt,the belt is a metallogenic belt of rare metals and precious metals. At present,five ore bodies have been found in the area,with two high degree of control( 1 and 3 ore bodies),and are controlled by interlayer tectonic shear belt,whose dominant metal is gold and associated or intergrown with silver and copper in the area. Ore types are carbonate and quartz vein and the gold originating in carbonate in the shear belt is the principal,the area is a metamorphic percolation hydrothermal tectonic altered rock-quartz-carbonate rock type gold deposits. The area is of metallogenic material source and the activation,migration and enrichment conditions, so the resource potential is tremendous and the promising prospect is brilliant and new breakthroughs can be achieved by strengthening the comprehensive prospecting.
