Discussion on the characteristics of gold deposits and the genesis of gold in the Huashan area of Dongzhi County
The tectonic position of the Huashan gold mine area is located in the southern part of the Jiangnan transition zone,on the south side of the Jiangnan deep fault,and from the east to the west side of the fault.The ore body is controlled by nearly east-west trending faults,and the ore bearing rocks are the early Cambrian Yangliugang Formation striped mudstone and clay shale.The main ore minerals are pyrite,arsenopyrite,antimonite,etc.Among them,granite diorite porphyry pyrite mineralization is developed,sericite mineralization is developed,and is accompanied by more common vein disseminated gold mineralization,which has the characteristics of porphyry type gold deposits.In the Jiangnan transition zone,medium acidic porphyry should be the focus of searching for porphyry type gold deposits.The indicators for mineral exploration include structure,lithology,and alteration.
