摘要
通过对丫叉桥地区的地热地质特征进行分析研究并开展野外地质调查工作,发现丫叉桥地区的控热构造为近东西向F8断裂构造带,导热构造为区内低次序派生断裂或断裂交汇处形成的裂隙带,地下热水主要接受低山丘陵区的大气降水渗入补给。在压力差的驱动下,热水沿着裂隙带在适宜的地貌条件下溢出地表成泉,综合分析认为该地区地热资源前景良好。
By analyzing and researching the geothermal geological characteristics of crotch bridge and conducting field geological survey work,it is found that the heat-controlling structure in the crotch bridge is a near-east-west F8 fault structure belt,and the heat conduction structure is a low-order derivative fault or fracture zone formed in break crossover point,the underground hot water is mainly supplied by the infiltration of atmospheric precipitation in low mountain and hilly area.Driven by the pressure difference,hot water overflows the surface and forms springs along the fracture zone under suitable geomorphic conditions.Comprehensive analysis shows that the geothermal resources in this area have a good prospect.
