    摘要:

    为研究内蒙古卫境地区构造特征及其与铀矿化的关系,在对高分二号数据进行大气校正等预处理的基础上,采用目视解译的方法,对卫境地区进行了构造遥感解译。经过野外查证,并结合已有的地质资料,分析了卫境地区构造分布规律,结果表明北东-北东东向F12和北北东向F11构造与次级近东西向构造、北西向构造等的交汇部位,是卫境地区铀成矿的有利空间。在敖包吐-苏莫查干敖包地区开展了1:1万γ能谱扫面工作,结果显示放射性异常主要分布在二叠系大石寨组三段的炭质板岩中,圈定了1处铀矿化异常带以及多处铀矿化异常点,显示该地区具有良好的铀成矿潜力。

    Abstract:

    In order to study the tectonic characteristics and its relationship with uranium mineralization in Weijing area of Inner Mongolia, the remote sensing technique and visual interpretation were applied to interpret the linear structure with GF-2 remote sensing data. Atmospheric correction and another preprocessing were processed on GF-2 remote sensing data before remote sensing interpretation. The distribution regularities of linear structures can be got from the field geological examination and the available geological data. The results indicates that the intersecting areas of NE-NEE trending structure F12 and NNE trending structure F11 with EW or NW trending structures are the favorable uranium metallogenic regions. The γ spectrum scanning work was carried out in Obotu-Sumochagan Obo area. The results show that the uranium anomalies are mainly distributed in the carbonaceous slate of the third member of the Permian Dashizhai formation, and one uranium mineralization anomaly zone and several uranium mineralization anomalies are delineated. Which indicates that this area has good uranium mineralization potential.
