摘要
选取牛鼻子梁地区1:5万水系沉积物测量的21种元素为研究对象,对其地球化学参数特征及相关性进行了分析。通过元素异常特征、成矿地质条件及已知矿点信息,确定该区成矿类型主要有与超基性岩有关的铜-镍、与破碎蚀变带有关的金和与碱长花岗岩有关的铌-钽-稀土3类矿化。在异常圈定及分析基础上划分出青新界山金-铌-钽-稀土找矿远景区、牛鼻子梁铜-镍-金找矿远景区、牛鼻子梁西金-铌-钽-稀土找矿远景区,认为研究区寻找Cu、Ni、Au、Nb、稀土矿的潜力较大。
This study analyses geochemical characteristics and relationship of 21 elements,such as Au,Ag,Cu,Co,Ni,Nb,Ta and La,from the 1：50 000 stream sediment survey.On the basis of the characteristics of key stream sediment geochemical parameters of the beam area and its elements of correlation analysis,the study area is found to possess Cu,Ni,Au Nb and rare earth ore potentiality.Through element anomaly characteristics,metallogenic geological conditions and known mine information,three main metallogenic types are related to the ultrabasic rock copper nickel ore,gold and associated with broken alteration zone related to alkaline granite Nb-Ta rare earth mine.Then,according to the analysis and the anomaly,the area is divided into Qingxinjieshan gold vision Nb-Ta rare earth ore area,Niubiziliang determined which are key beam copper nickel gold prospecting prospective areas and western Niubiziliang Nb-Ta-rare earth oreprospecting prospective area of gold.
