摘要
为进一步开发和利用热水镇的地热资源,运用物探联合剖面法,结合区域地质和构造特征,分析、推断地下热水形成和运移的水文地质条件;推测出隐伏的断裂带;证实张性断裂对地下热水的控制作用;查明该区第四系中视电阻率<40 Ω·m的地层为含热水砂砾石层,圈定联剖曲线低阻带中视电阻率<100 Ω·m的范围为断裂构造脉状地下热水的中心部位。
The composite profiling method of exploration has been applied to further develop and utilize geothermal resource in the Reshui Town. Combining with regional geology and structure characters,the authors analyzed and speculated the formation and transportation hydrogeological condition of geothermal water and the buried geological fracture,and verified the control of expanding fracture over geothermal water. The authors also found that sand and gravel layers contain geothermal water by the apparent resistivity less than 40 Ω·m in Quater- nary,and encircled the central parts of veined geothermal water in faulted structure based on composite profiling curves with the apparent resistivity less than 100 Ω·m within low resistivity zones.
