摘要
团风县金鸡坳金矿区位于湖北省大崎山穹窿南西缘,矿体严格受断裂构造控制,垂向上具有金银矿化向金银多金属矿化转变的特征。矿区储矿构造主要为北西向和近东西向脆性断裂,且其不同方向次级断裂构造的交汇部位为矿化富集有利部位。矿区金成矿事件与燕山期构造—岩浆热液活动关系密切,矿床成因类型为中低温岩浆热液型金矿床。地表及深部地质、地球化学异常显示,祝家冲矿段具有较好的找矿潜力,深部可能存在工业矿体。
Jinji ao Gold Deposit in Tuanfeng is located in the southwest of Daqishan cove.The ore body,strictly controlled by the fault structure,changes from gold-silver mineralization to gold-silver polymetallic mineralization vertically.The depositing structures are brittle fractures mainly in N-W and nearly E-W direction.The joint positions of secondary fault in different directions are enriched mineralization centre.The metallogenic event of gold deposit is closely related to tectonic-magmatic hydrothermal activity in Yanshan period.The genetic type of mineral deposit is medium and low temperature magmatic hydrothermal type.The surface and deep geologic conditions and geochemical anomaly show that Zhujiachong ore block has a good prospecting potential and there may even exist an ore body in the deeper part of the earth.
