| |
| Abstract: | By studies in field or under microscope,the gold minerals are found to be composed of gold,silver and silver bearing gold in the Dingjialin and Taiyangping gold fields.The Dingjialin gold field are predominated by the inclusion gold ;whereas the Taiyangping gold field are predominated by the fracture gold.Grain amount and area statistic show that medium or fine grained gold are predominent in these two gold fields.The carrier minerals are mainly pyrite,quartz and few galena,chalcopyrite and sphalerite.The mineralization and enrichment of gold are characterized by the rich pyrite and poor other polymetallic sulfide.Coarse grained gold,giant grained gold and block gold are the common visiable gold in ores. |
