| 摘 要： | 秦楼铜金矿是三铺地区以金为主的矽卡岩型铜金矿床,位于安徽省濉溪县四铺乡秦楼村北部。矿区位于三铺岩体北接触带东端,岩体复杂,接触带及围岩层间裂隙为主要控矿构造。通过对秦楼铜金矿地质特征及矿床特征的认识,结合矿床物探异常特征,系统总结了三铺地区铜金多金属矿地质和物探找矿标志。研究表明:寒武纪中上统碳酸盐岩地层是三铺地区铜金多金属矿重要的赋矿层位;燕山期早白垩世的中酸性侵入体是寻找铜金多金属矿重要的标志;矿体赋存于局部磁异常的边部、局部磁异常梯级带上及布格重力异常梯级带上,为本区寻找铜金矿床指明了方向。

| Abstract: | Qinlou copper gold deposit is a skarn type copper gold deposit dominated by gold in Sanpu area. It is located in the north of Qinlou village in Sipu town of Suixi county in Anhui province. The mining area is located in the east end of the north contact zone of Sanpu rock mass. The rock mass is complex. The main ore controlling structures are the contact zone (multilayer bifurcation intrusion, multilayer mineralization) and the interlayer fissures of surrounding rock. Based on the understanding of geological characteristics and deposit characteristics of Qinlou copper gold deposit, combining with geophysical anomaly characteristics of the deposit, geological and geophysical prospecting indicators of copper gold polymetallic deposit in Sanpu area have. been summarized systematically in this paper. It is showed that the carbonate strata of middle upper Cambrian is an important ore bearing horizon of Cu and Au polymetallic deposits in Sanpu area. The Yanshanian early Cretaceous intermediate acid intrusive body is an important indicator for looking for Cu and Au polymetallic deposits. The ore bodies occur in the edge of local magnetic anomaly or on the local magnetic anomaly ladder belt, and on the Bouguer gravity anomaly ladder belt. It will point out the direction for looking for Cu and Au deposits in this area. |
