摘要
通过研究南戈滩多金属矿区的成矿地质特征,解析高精度磁法测量异常,初步认为南戈滩矿区奥陶—志留系沙柳河群((O-S)sa)为主要的赋矿地层,花岗闪长岩体为成矿提供了热液和动力,NE向构造为主要的容矿构造。区内多金属矿(化)体磁性特征与围岩差异性大,开展的磁法测量效果明显,磁异常发育地段与矿(化)体对应较好,表明南戈滩矿区具有较好的找矿前景。
Though studying the metallogenic geological characteristics of Nangetan plymetallic mining area,analyz-ing the magnet anomalies of high accuracy magnetic survey,we preliminarily think that the（O-S）sa stratum is the main mining stratum,the granodiorite rock mass provides hydrotherm and motivity for mineralization,and the NE fault is the leading host structure.The magnetic difference between polymetallic orebodies and wall rok is distinct,the purpose of magnetic surveying is obvious,the area of magnetic anomaly and ore-bodies are corresponding.By means of analysis from geological characteristics,integrate magnetic survey result,speak volumes for the Nangetan ore area is well prospecting potential.
