摘要
Abstract
Outcrops strata are Yuanhe group and west Huashan group, belong to Changcheng system of Mesoproterozoic, except south Huashan group. The main block of the west Huashan group is composed of a syncline and an uncompleted anticline with east-west axial direction. Faults are well developed in the area, and the area is cut by faults from south to north. NWW and NE faults also developed. West Huashan gold ore deposit located in Machang-Heiquan and Liugou area. The gold mineralization is closely related to spessartite veins and quartz veins. Contrast with Xiaoqinling gold mine, gold geochemical parameters are anomaly with significantly dispersed mineralization characteristics, the gold ore-forming fluid in this area is acid with higher pressure and temperature conditions and low CO2 mass fraction. The mineralization characteristics are more decentralized and it is hard to form large ore deposit.关键词
