玄中寺地热水化学特征分析

Chemical Characteristics Analysis of Xuanzhong Temple Geothermal Water

在分析交城县玄中寺地质和地热背景条件的基础上,探讨了地热水的主要化学成分特征和形成机制。分析结果表明,热水属于低矿化高氟水,水化学类型为HCO3.Cl-Na型水,与断裂带附近其它水井化学成分有明显的差异;热水系统是一个还原环境,地热水源自近期大气降水,是在交城县北部山区获得降雨入渗后经深循环而形成的。研究结果为合理开发利用玄中寺地热水具有重要的指导意义。

Based on the analysis of geology and geothermal condition of xuanzhong temple in jiaocheng county, the characteristics and formative mechanism of the main chemical components are discussed in this paper. The results show that the geothermal water belongs to low minerali zation high F water and the hydrochemical type is HCO3 ·CL-Na, and have obvious difference in chemical component between Xuanzhong temple well and other wells in the jiaocheng rapture. The geothermal water system belongs to a reductive environment, the geothermal water is recharged by precipitation in North of jiaocheng county and circulates in deep stratum. This researcher is significant for directing reasonable exploiting and utilizing the geothermal water.
