:榆中盆地地热异常区 ,处于区域性地热背景之上 ,具有深源热机制。应用电测深推断盆地基底构造、盖层结构 ,其中部断阶带基底隆升 ,断裂构造发育 ,储、盖层具备 ,是地热赋存有利部位。由电测深曲线极小值视电阻率圈定出热异常的范围、导热构造 ,为地热评价、开发提供依据 : The geothermal anomaly zone in the Yuzhong Basin is above the regional geothermal background and has a deep-source thermal mechanism. Based on electrical sounding, it is concluded that the basement structure and the cover structure of the basin are well covered by basement uplift and fault structure in the middle part of the basin, and the reservoirs and cap rocks are available for geothermal occurrence. Determined by the minimum value of the electrical sounding curve depending on the resistivity thermal abnormalities range, thermal structure, geothermal evaluation and development provide the basis
