摘　　要：地热水在高温高压的环境下,在岩石的裂隙中缓慢地渗透、运移,达到了有利溶解的新热动力平衡,致使围岩发生蚀变,围岩中有新的物质溶入水中,使地热水化学指标与周围环境水有明显的区分特征,表现为F-、SiO_2、pH值3项指标明显高于环境水。以上述3项指标作为示踪元素,在丹东市炮守营温泉区寻找地热水,结果显示,该方法可明确界定地热区域的范围,缩小勘查目标,降低原有的工作量和资金投入。Geothermal water in high-temperature and high-pressure environments slowly infiltrates and migrates through fissured rocks to achieve a new thermal and dynamical balance conducive to dissolution, resulting in wall rock alteration. In the surrounding rocks, new substances are dissolved in the water, which enables the chemical indicators of geothermal water to be different from those of the surrounding environmental water, as shown by the fact that the values of F, SiO2 , and pH are much larger in geothermal water than in environmental water. We used the three indicators mentioned above as tracer elements to search for geothermal water in the Paoshouying hot spring area, in Dandong City. The results show that this method can explicitly define the boundaries of geothermal regions, narrow down the investigation targets, and reduce the original workload and capital investment.
