陕西省石泉县柿子沟金矿地质特征及控矿因素浅析OA

The Shizigou gold deposit in Shiquan County,Shaanxi Province,is located in the northwest of the county.Its tectonic position is in the early Paleozoic rift(O-S)(III12)of the Yangtze Plate,from Zhouqu to Ankang.It belongs to the Shiquan Ankang gold manganese mineralization zone and has favorable mineralization conditions.Through geological,geochemical,and exploration engineering methods and means,the ore-forming geological conditions of the mining area have been preliminarily identified.Two mineralized alteration zones have been identified within the carbonaceous schist section of the Meiziya Formation in the Lower Silurian,and multiple gold(mineralized)bodies have been identified within these zones;The mineralized alteration zone and mineralized body are controlled by the Lower Silurian Meiziya Formation and F5 ductile shear structure.The coupling of geochemical anomalies with the distribution of strata,structures,and other factors is significant,indicating the potential for mineralization of sedimentary metamorphic hydrothermal deposits controlled by ductile shear zones.
