摘要
利用以往工作取得的水化学分析数据,对比分析了大孙庄氡温泉水和中土楼地热水水化学特征,总结了热水成因模式。结果表明:大孙庄氡温泉水和中土楼地热水水化学特征具有普遍一致的特点,仅个别离子元素存在明显差异;地热温泉水中溶质组分主要来源于水-岩溶解作用,其形成主要受地层岩性、地质构造、水动力条件等因素影响;二者虽然受不同的深部断裂构造控制,但却具有相似或相同的补给来源和水文地球化学过程。利用玉髓温标计算的大孙庄氡温泉井热储温度为44.0~45.7℃,中土楼地热井热储温度为48.9℃;研究区地热系统属于中低温深循环型基岩裂隙带状地热系统。
Using previously acquired hydrochemical analyzed data,comparatively analyzed hydrochemical features of the Dasunzhuang radon hot spring water and Zhongtulou geothermal water,summarized hot water genetic mode.The result has shown that the hydrochemical features of the two sites have general agreement features,only individual ions or elements existed significant differences.Source of solute components in geothermal hot spring water is mainly from rock water dissolution,mainly controlled by impacts from strata lithology,geological structure,hydrodynamic condition etc.Although the two have controlled by different deep part faulted structures,but have similar or same recharge sources or hydrogeochemical processes.Using the chalcedony thermometric scale computed Dasunzhuang radon hot spring geothermal reservoir temperature is 44.0~45.7℃,Zhongtulou geothermal well reservoir temperature 48.9℃.Thus study area geothermal system belongs to medium low temperature deep circulation type bed rock fissure banded geothermal system.
