青海省芒崖镇大通沟南山地区遥感地质特征及找矿预测

大通沟南山属于阿尔金南缘成矿亚带金鸿山—茫崖金、铜、钨多金属找矿预测区,其地球化学和地球物理异常发育,具有优越的成矿地质条件及良好的找矿潜力。鉴于大通沟南山地处高寒山区,地理环境恶劣、野外地质调查工作困难等问题,文章利用多源遥感卫星数据,在其区内开展了全面的地质解译以及蚀变信息提取工作,并结合已有的地质矿产及物化探资料,对区内的成矿地质条件及找矿远景进行了分析预测,圈定了3处遥感找矿远景预测区,可为后期野外地质找矿工作提供帮助。

Remote sensing geological characteristics and prospecting prediction in Nan mountain of Da Tong ditch, Mangai Area, Qinghai

The study area,the Nan mountain of Da Tong ditch is located in the Jinhongshan-Mangai Au,Cu and W prospecting prediction area of the south marginal sub-ore belt of Altyn Tagn mountains.The geophysical anomalies and geochemical anomalies and geological condition here are potential for prospecting.Here is in the high and cold mountains with harsh geographic environment and difficulties for caring out geological work.The authors made use of multi-source satellite remote sensing data to interpret geological features and abstract alteration information based on the previous geological,geophysical and geochemical data.then analyze the prospecting potential and locate 3 targets for further field ore prospecting.
