1矿床地质鸡头山Mo-W矿位于长江下游池州市南约40km处。矿区内发育主要构造单元-鸡头山背斜,背斜核部由中寒武系杨柳岗组地层组成;背斜因受构造岩浆活动侵入,南东翼地层缺失不对称。断裂以北东-南西向延伸压扭性断裂为主,大部分为后期的花岗斑岩脉所充填,断裂方向与区内的基岩 1 Deposit Geology Jitsuoshan Mo-W Mine is located about 40km south of Chizhou in the lower reaches of the Yangtze River. The main tectonic unit developed in the mining area is Jikoushan anticline and the anticline core which is composed of the mid-Cambrian Yangliugang Formation. Because of intrusive tectonic magmatism, the anticlinal anomaly is not symmetrical. The faults are dominated by the extensional compressive-shear faults in the NE-NS direction, most of them are filled with granite porphyry veins in the later period, and the fracture directions are in line with the bedrock of the area
