摘要
松桃县普觉锰矿区浮土掩盖严重,追索地质构造线特别困难。为调查尖山至猴家庄一带隐伏断层特征及锰矿层分布,采用EH4连续电导成像仪作了1条大地电磁法测深试探剖面。物探异常显示:F1断层面呈低阻到高阻电性不连续界面,断面向呈波状起伏近直立分布;物探异常还显示:F1断层东盘含锰地层出现一背斜一向斜褶皱构造,背斜轴面倒转。试探结果证明EH4物探方法对探测该地区深部隐伏地质构造具有重要的指导意义。
As Pujue manganese ore field is heavily covered by arid regolith,it's very hard to determine the geological structure line.In order to investigate the hidden fault characters and manganese ore bed distribution from Jianshan to Houjiazhuang,the magentotelluric depth sounding is done to one section,the geophysical anomaly show that F1 fault plane is noncontinuous plane from low resistivity to high resistivity,it distributes almost vertically as crinkle.The geophysical anomaly also shows the eastern manganese bearing stratum of F1 fault has anticline-syncline structure and the anticlinal axis is inverse.The test shows EH4 geophysical prospecting method has guiding significance for determine the deep hidden geologic structure in this area.
