摘    要:北京奥林匹克公园地区是北京一个新的地热资源区。通过地热水流体地球化学、氢氧同位素、氚同位素和14C测年等数据,结合该地区地质和地热地质背景,对该区地热水的地球化学特征和形成机制进行了分析探讨。该区地下水水化学类型以碳酸、硫酸、盐酸钠型水(HCO3--SO24--Cl--Na+)为主,亦有少量硝酸、重碳酸、钙镁型水(NO3--HCO3--Ca2+-Mg2+)。地下热水不具有现代大气降水的补给特征,其径流状态与区域断裂系统有关,是介于地热源水和深层地下冷水之间的混合型地下热水,地热源水大约形成于20000~30000aB.P.。该区地热水具有较高的开采利用潜力。

关 键 词:地热水  地球化学特征  形成机制  北京

Abstract:Beijing Olympic Park Area is a newly discovered geothermal resource area in Beijing. Based on the geochemistry,H-O isotopes,tritium isotopes and 14C dating data of the geothermal fluid and combining the geothermal geology background,we have studied the characteristics and the formation mechanism of the geothermal fluid in this area. The major hydrochemical type of the geothermal fluid is the type of HCO-3-SO2-4-Cl--Na+,and the minor one is HCO-3-NO-3-Ca2+-Mg2+ type. The geothermal fluid was not supplied by ...
Keywords:geothermal water  geochemical characteristics  formation mechanism  Beijing
