摘要
寨上金矿现为西秦岭特大型金矿,赋矿地层主要为泥盆系、二叠系,矿体产在NWW向断裂及次级断裂中,富含金属硫化物。矿区西部古近系、第四系覆盖较厚,据现有地质资料综合分析,认为覆盖区下部成矿条件有利,通过物化探工作,推断覆盖区下部存在金矿体,浅钻验证见矿。
The Zhaishang gold deposit is a superlarge gold deposit in West Qinling Mountains, which is mainly hosted in Devonian and Permian strata and occurs in NWW-trending as well as second-order faults. It contains rich metallic sulfides. In the western part of the ore district, there exists rather thick Tertiary and Quaternary overburden. An integrated analysis of the geological data available shows that metallogenic conditions are fairly favorable beneath the overburden area. Through geophysical and geochemical prospecting work, the authors inferred that there might exist a gold ore body under the overburden area, and shallow drilling has eventually intersected the ore body.
