胶东温泉地热水水化学及同位素特征研究

Study on Hydrochemistry and Isotopic Characteristics of Geothermal Water in Jiaodong Area

摘要:

对胶东半岛出露的14处温泉的水化学特征、同位素特征进行了分析，得出胶东半岛温泉水的来源主要为大气降水补给、海水补给，年龄以现代水为主。胶东半岛温泉水与围岩矿物未达到完全平衡，不适宜用Na，K，Mg地热温标，玉髓的地热温标显示胶东半岛温泉热储温度在81.26～108.93℃之间。对下一步胶东半岛的温泉地热勘查、开发利用具有指导意义。

Abstract:

Hydrochemical characteristics and isotope characteristics of exposed 14 spa water in Jiaodong Peninsula are analyzed in this paper. It is regarded that the source of hot spring water in Jiaodong Peninsula is mainly precipitation recharge and water supply. The forming age mainly belongs to modern water. Spring water in Jiaodong Peninsula and minerals of country rocks can not meet the full balance. It is not suitable for using Na, K and Mg geothermal temperature scale. As showed by geothermometers of chalcedony, the reservoir temperature of geothermal hot springs in Jiaodong Peninsula is 81.26~108.93 ℃. It will provide references for further exploration, development and utilization of geothermal springs in Jiaodong peninsula.
