柳林泉域滞流区低温岩溶热水的年龄分析
Dating of low-temperature geothermal karst groundwater in the stagnant area of the Liulin spring drainage
摘要
Abstract
The purpose of this work is to investigate the age of low-temperature geothermal karst groundwater in the stagnant area of the Liulin spring drainage.According to regional geological and hydrogeological conditions and field sampling and analysis,taking the Henggou artesian wells in the stagnant area as an example,the isotope dating techniques,including δ2H(‰),δ18O(‰),3H(TU) and 14C (pMC)),were employed to estimate or correct the age of karst groundwater.By analyzing the relationship between 3 H and 14C and the values of δ2H and δ18 O,the karst groundwater in Henggou is considered to be an ancient karst groundwater,probably older than 10,000 a.The age estimated by 14C also supported this estimation.Besides,the calculated ages are 12,908 a and 9,090 a for Henggou 1 # artesian well and Henggou 2 # artesian well,respectively.Thus,the karst groundwater nearby Henggou should be recharged during the last glacial culmination.关键词
