| Abstract: | The Xinshan Au deposit is a typical Au deposit controlled by structure shear zone,in the metamorphic quartz sandy slate in the middle part of Middle Proterozoic Kunyang Group Meidang Formation（Pt2m）.It is an ore deposit with large scale,rich grade and easy mining-dressing characteristics.The important ore prospecting criteria are the structure-Au bearing shear zone and Au geochemical anomaly in soil. |
