| Abstract: | The Sandaowanzi gold deposit is a mesothermal-epithermal volcanogenic gold deposit which located in the DaHinggan Mountain metallogenic belt of Yanshanian epoch.Mineralization is mostly hosted within quartz veins.The ore textures include automorphic-hypautomorphic-xenomorphic granular,cataclastic,metasomatic and poikilitic.The ore structures mainly show massive,disseminate,brecciated and veinlet.At shallow depth the gold occurs as fine grained native gold and electrum,and distributes in fissures,intergranul... |
