柳林泉域滞流区低温岩溶热水的年龄分析

为了研究柳林泉域西部滞流区低温岩溶热水的年龄,在区域地质、水文地质条件调查及野外取样、分析的基础上,以滞流区横沟自流井的岩溶热水为例,利用δ~2 H（‰）、δ^18 O（‰）、^3 H（TU）和^14C（pMC）同位素测年技术分析、计算并校核了该区岩溶水的滞留时间。通过分析岩溶水中^3 H和^14C的关系及其δ~2 H、δ^18 O值,表明横沟岩溶水属于古岩溶水,其年龄应在10 000a以上;利用^14C计算并校核后的岩溶水年龄也印证了这一点,横沟1#和2#井岩溶水的^14C年龄分别为12 908a和9 090a。因此,横沟附近岩溶热水应属于末次冰期盛冰期内补给的古岩溶水。...

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 δ^2 H（‰）,δ^18 O（‰）,^3 H（TU）and ^（14）C（pMC））,were employed to estimate or correct the age of karst groundwater.By analyzing the relationship between ^3 H and ^14 C and the values of δ^2 H and δ^18 O,the karst groundwater in Henggou is considered to be an ancient karst groundwater,probably older than 10,000 a.The age estimated by ^14 C also supported this estimation.Besides,the calculated ages are 12,908 aand 9,090 afor Henggou 1#artesian well and Henggou 2#artesian well,respectively.Thus,the karst groundwater nearby Henggou should be recharged dur
