摘要
通过对阳谷-齐河凸起地下热水的化学成分、同位素及其地热地质条件的分析,对这一地区的地下热水的补给来源进行了研究。本区地下热水的δD为-65‰~-80.67‰,δ18O为-9.2‰~-10.2‰,均分布在全球雨水线的附近,说明该区地下热水主要为大气降水成因。济南北地热田地下热水的补给高程为256m,此范围大致相当于济南南部山区及其以南的泰山北麓;聊城东地热田地下热水的补给高程为411m,此范围大致相当于泰山山脉及其周边的中山区。聊城东地热田地下热水的2H过量参数d明显低于济南北地热田,说明聊城东地热田地下热水的补给区比后者更远。
Based on analyzing the chemical composition,isotope,terrestrial heat and geological condition,this paper studied supply sources of ground hot water in this area. The δD is -65 ‰ to -80.67 ‰ and the δ18O is -9.2 ‰ to -10.2 ‰,both are located in the vicinity of the global rainfall line indicating the main cause of ground water in the area is atmospheric precipitation. Northern Ji'nan geothermal field ground hot water supply elevation is 256m,which is roughly equivalent to the mountains south of Ji'nan and the northern foot of Taishan mountain; while geothermal field ground hot water supply elevation in the east of Liaocheng is 411m,which is roughly equivalent to Taishan mountain and its surrounding mountains. Excess parameter of deuterium(d) of geothermal field ground hot water in the east of Liaocheng was significantly lower than that of geothermal field in the north of Ji'nan. It indicates that geothermal field ground hot water supply area in the east of Liaocheng is farther than the latter one.
