摘要
南戈滩矿区处在祁满塔格—都兰早古生代弧后残留盆地,区内地层以奥陶—志留系沙柳河群为主,构造以NE、NW向为主,NE向是矿区主要的容矿构造,主要出露印支期花岗闪长岩和二长花岗岩,具备了较好的成矿地质背景。区内磁异常特征明显,具有较好的铁、铜、金及多金属找矿前景。
Nangetan mine area located in Qimantage-Dulan back-arc residual basin at early Paleozoion.The stratum of this area is mainly Ordovician-Silurian Shaliuhe group,structure is mainly NE、NW trending.NE trending is mainly host structure,expose Triassic granodiorite and monzogranite,it has a good geological background.The characteristics of regional magnetic anomalies are evident,and it has a good iron,copper,gold and multi-metal exploration prospecting.
