摘要
调查区为内蒙古额济纳旗基东等四幅1:5万矿调区,地处我国重要的北山成矿带,区内广泛发育中酸性侵入岩体,其中闪长岩体主要分布于西林陶勒幅,该闪长岩体多侵入在公婆泉组地层中而被后期黑云母花岗岩和钾长花岗岩所侵入。闪长岩体中构造很发育,成矿条件优越。地表矿化线索和化探异常显示,该区化探异常明显,地质单元有侵入岩也有变质岩,断裂纵横交错,非常发育,是成矿的有利地质部位,闪长岩体具有很大的成矿潜力,有良好的找矿前景。
Inner Mongolia Ejinaqijidong four 1：50000 mine exploring areas lies in the key Kitayama ore belt ,neutral - acdic intrusive bodies are widely developed in the area, diorite pluton is mainly distributed in the Xilintaole,and a small amount expose in the northeast comer of Jianshan and southeast comer of Shizhuangzijing. The dioritic rock mostly invade in Gongpoquan group and was lately invaded by biotite granite and K - feldspar granite intru- sion. Structure is widely developed in diorite rock, ore forming conditions is favorable, the surface mineralization and geochemical anomaly clues show di- orite rock ore has great mineralization potential.
