宾川小龙潭找矿转向西南5个异常区的证据

The evidences about prospecting of Xiaolongtan in Binchuan country should turn to five anomaly areas southwestward

  • 摘要: 综合地物化遥信息,宾川小龙潭斑岩铜矿区的找矿部位只有转向核桃箐断裂F2西南的5个综合异常区,才能扭转多年钻探几上几下的被动局面.这是因为其大地构造处扬子板块中的盐源-丽江陆缘坳陷和滇中的拗陷交界线、宾川-程海超壳断裂上盘一侧,其深部壳幔界面深51~52 km、由陡变缓的拐折成矿有利部位,其内又有51,52 km两个像波浪起伏似的波台区,面积约1.4104 km2,它是赋存和寻找超大型矿床的规律之一;小龙潭的幔距约10 km,幔角0.4,是超大型矿床的规律之二;它深部像北衙超大型金矿床一样,有二叠系峨眉山玄武岩岩浆房提供充足的含铜金矿液.它的5个异常区也是由于壳幔界面凸凹不平而形成的400~500 m似等间距的区段.简言之,期冀在小龙潭区找到超大型斑岩铜矿床.

     

    Abstract: In consideration of overall the information of materialized remote sensing,we thought that the prospecting orientation of Xiaolongtan copper mine should turn to five anomaly areas southwestward in F2 breakage of Hetaoqing,that probably can change the passive situation of drilling.Because its tectonic plate lies in the juncture between continental margin depression of Yanyuan-Lijiang and depression of Middle Yunnan,also lies in the side of rapture hanging wall of Binchuan-Chenhai super shell.The depth of crust-mantle is 5152 km,the stagger from steep to slow became the advantageous position of mineralize,the position has two waveform stations deep 51 and 52 km respective,their areas are 1.4104 km2.The curtain distance of Xiaolongtan is about 10 km,and its curtain angle is 0.4.The deep part has abundant ore solution contained copper and gold which provided by the magma reservoir of the Emei basalt.The five anomaly were formed by uneven of mantle interface, and their distances are 400500 m.In short,we hope to find ultra-large porphyry copper in Xiaolongtan.
