瞬变电磁测量在吐哈盆地十红滩铀矿区勘查中的应用效果

The Application Effect of TEM for Uranium Prospecting in Shihongtan Area of Turpan-Hami Basin

将瞬变电磁法应用于吐哈盆地十红滩地区铀矿勘查,采用分离回线装置方式进行测量,划分了找矿目的层的结构、埋深、厚度及空间展布特征,基本查明了矿区基底隐伏断裂及褶皱构造位置,研究认为解释出的构造与砂岩型铀矿成矿关系密切,对该地区铀矿找矿工作具有一定的指导作用。通过后期钻孔验证,取得了良好的地质效果。

Transient electromagnetic method （TEM）was applied in uranium exploration in Shihongtan area of Turpan Hami Basin. By using separated return wire installment,the stratigraphic structure, the buried depth,the thickness and spatial distribution of target layer has been identified ,and the distriG bution of basement hidden fault and fold structure in ore district were basically found out.The research shew that interpreted structure has close relationship with ore formation of sandstone type uranium deposit and can play guiding function in the exploration of uranium deposit in this area.Later drilling valiG dation has achieved obvious geology effect.
