| Abstract: | Suishizi gold deposit located in west Qinling mountain is controlled by both diorite-porphyrite veins and fault fractured zone.The upper orebody produced in the fractured zone near the diorite-porphyrite veins,while the lower orebody hosted in the diorite veins.Pyrite,chalcopyrite,galena are the main mineral compositions of ore,and pyrite is the main mineral carrier of gold and silver.Small vein-disseminated and small vein-network structures are the main structures of the ore,which indicates the deposit has... |
