摘要
阿拉善左旗呼和沙拉矿区中的乌力吉—巴尔布拉格铜多金属矿成矿带作为内蒙古西北部地区主要成矿带之一,具有比较优越的成矿地质条件。根据区内自然地质情况,首先利用TDEM法和CSAMT法查明普查区内隐伏断裂构造的分布及深部变化特征,查明岩浆岩与沉积变质岩接触带的展布特征,圈定与成矿有利的构造及矿化蚀变带的位置;根据区内成矿地质特征及TDEM法、CSAMT法所圈定成矿有利地段,利用SIP法圈定与成矿密切相关的金属硫化物富集体,最终通过该综合物探法为地质钻探工程的部署提供依据。
As one of the main metallogenic belt in northwestern Inner Mongolia, Wuliji-Baerbulage copper polymetallic ore belt in Huheshala mining area in Alashanzuoqi banner has superior ore forming geological conditions.According to natural geological conditions in this region, by using TDEM method and CSAMT method, the distribution of hidden fault structures and change characteristics in deep part, the distribution characteristics of magmatiteand sedimentary metamorphic rock contact zone have been identified, and delineation and tectonic mineralizationalteration belt and advantageous position have been circled. According to metallogenic and geological characteristics, favorable mineralization areas have been circled by using TDEM method and CSAMT method, by using SIPmethod, ore forming metal sulfide which has close relation with mineralization has been circled. Through integrat？ed geophysical method, it will provide basis for engineering geological drilling arrangement.
