摘要

麻布山地区位于国家级整装勘查区庐枞铁、铜、硫铁矿重点勘查区范围内。区内赋存的三叠系中统铜头尖组第一岩性段及下伏的东马鞍山组地层,是寻找铁矿的理想层位;发育的石英正长岩体和钾长花岗岩体,均属有利于成矿的中酸性岩浆岩中的碱性系列;早于岩体形成的各向断裂构造,是区内重要的导矿、容矿构造。结合成矿地质条件及物探重、磁异常特征,预测的以姚坂找矿靶区为主的3个铁矿成矿靶区,具有良好的找矿前景。
        Linen mountain is located in the state-level ready exploration area of the dormant fir iron, copper, pyrite within the key exploration area. The occurrence of Triassic middle copper head group of the first lithologic section east ma on shan group and the underlying stratum, is ideal for iron ore horizon; Development of Shi Yingzheng rock mass and potassium long granite rock mass, are conducive to mineralization of intermediate-acid magmatic rocks of the alkaline series; Before the formation anisotropy of rock mass fracture structure, is an important guide in ore, ore structure. Combined with ore-forming geological conditions and gravity and magnetic anomaly characteristics, geophysical prediction is given priority to with yao tranship prospecting target areas of the three iron ore metallogenic target, has good ore prospects.
