Abstract: The Xiaoqinling mineralization zone trending east to west included five gold mineralization abundant zons(subore zone),in Wenyu-Yangzhaiyu subore zone,the ore veins are the most dense,the quantities of ore deposit are the inost. There are two kinds of gold mineralization in this region, that is gold-bearing quartz vein type and altered rock type, they have the supplementary feature in space and certain zoning tendency. In the whole region,from west to east, quartz vein type of mineralization became weak, and altered rock type of mineralization became strong. At the east part of Xuejashan,rock body contributed some small deposits of altered rock type. Gold-bearing quartz vein type of mineralization developed mostly in the shallow part,while altered rock type of mineralization developed mostly in the deep part.
