摘要
通过对咸阳地压地热流体的环境同位素研究,系统论证了咸阳地压地热流体的补给来源、补给方向及补给年代。研究表明:咸阳地压地热流体的补给来源主要为全新世前古大气降水,其补给方向主要来自研究区西部及西北部,除局部深大断裂附近有少量现代降水补给外,其可更新能力较差。
By systematically illustrating the recharge source, direction and period of geopressured geothermal waters in Xianyang by studying environmental isotope, the result shows that the main recharge source originates from mospheric water pre-Holocene Epoch, which is from the west and northwest of study area. Its updating ablility is poor except partial deep fault slightly recharge from modern mospheric water.
