CSAMT法在松辽盆地四平地区铀矿勘查中的应用

为进行四平地区的铀矿勘查,选择了抗干扰能力较强的CSAMT法进行铀成矿地质环境的研究.通过对CSAMT法的技术条件试验、井旁测深试验,确定了适合于本地区的方法技术参数、探区内各电性层与其对应地层的关系以及砂体的电性分布特征,并以此为依据对CSAMT法取得的成果资料进行了推断解释.经钻孔验证,取得了较好的地质成果.

THE APPLICATION OF THE CSAMT METHOD TO URANIUM EXPLORATION IN SIPING AREA, SONGLIAO BASIN

In uranium exploration of Siping area, the CSAMT method which has relatively high anti-interference capacity was adopted to conduct the study of uranium metallogenic geological environment. According to technological condition test of this method and sounding test beside the well, the technological parameters suitable for this area were determined, various electric layers in relation to corresponding strata in the prospecting area were defined, and the electric distribution characteristics of the sand bodies were detected. On such a basis, inference and interpretation of the data obtained by the CSAMT method were carried out. Drilling verification shows that the geological results of this method are satisfactory.
