山东莘县凹陷聊城段地下热水化学特征及成因
摘要:典型地区地下水成因和演化机制的研究不仅对于热水资源的合理利用与开发具有重的指导意义,而且可以为日后的地热资源勘查评价提供重信息。通过对莘县凹陷聊城段的地下热水的化学成分、同位素及其水文地质特征的分析,进而对这一地区的地下热水的成岩和演化过程进行了研究。地下热水的形成受区内深大断裂和基底构造对地热形成的控制,地下热水补给是来自大气降水,为入渗变质水,水化学成分以易溶盐溶解作用为主,反映了地下水长期径流及深循环中各种水化学作用。
Abstract:Studies of the origin and evolution mechanism of groundwater in a type area not only have great slgnificance for guiding the rational utilization and development of geothermal water resources but also provide important information for future geothermal resource exploration and evaluation. The formation and evolution of geothermal water in the Shenxian Hollow (Liaocheng segment) is studied based on an analysis of the chemical composition, isotopes and hydrogeological characteristics of geothermal water in the area. The study shows that the formation of the geothermal water is controlled by deep faults and basement structure in the area, the hydrochemical components consist predominantly of more soluble salts, and gas components are mainly marked by a mixture of components originating from the atmosphere, all these reflect the various hydrochemical processes in long-term run-off and deep circulation of groundwater.
