摘要
撒岱沟门钼矿是与印支期二长花岗岩有关的斑岩型钼矿床,控岩构造为南北向和东西向断裂构造,节理是主要的容矿构造.钼矿化赋存于岩体接触带附近的节理带及碎裂岩带中,钾化与矿化关系密切.根据钼矿控矿因素、物化探异常和遥感信息,预测Ⅰ级钼找矿远景区2处,Ⅱ级钼找矿远景区4处.
Abstract
Sadaigoumen molybdenum deposit is a porphyry - type molybdenum deposit related to granites of Yinzhi oblique joint and potassium feldspar, the tache rock - shape in the special geological period,. The controlling structures are north - south and west - east oriented. Its joint is the main structure of conrolling deposit. Molybdenum mineralization lies in the joint belts near rock body contact belts and cataclastic rock belts. There is a direct relation between potassium feldspar evolution and mineralization. According to some factors controlling molybdenum , geophysical and geochemical prospecting abnormality and information of remote sensing, we have predicated two prosperous areas scale -1 molybdenum and four prosperous areas scale - II molybdenum respectively.
