罗溪温泉水文地球化学特征及热水来源
|
摘要
本文选取江西省罗溪温泉为研究对象,综合应用地质、水化学和同位素等手段,对其水化学特征及来源进行系统研究,为热水的可持续开发利用提供了科学依据。研究表明:温泉为HCO_3·CO_3-Na型热水,可作为含F和H_2S的医疗热矿水进行开发,但不宜作为灌溉用水使用。通过分析温泉的D、~(18)O及~(87)Sr/~(86)Sr同位素资料,可知热水的补给来源为温泉东西方向海拔约950m的山区的大气降水,降水与地壳中岩石相互作用形成温泉。利用Person法修正热水的~(14)C年龄约为19 800年。通过计算推测热储温度约为82℃,循环深度为1 900m左右。温泉为花岗岩中地下水获得大气降水补给入渗后,经深循环加热上升出露而成。
Luoxi hot spring in Jiangxi province is selected to be the study area.The water chemistry characteristics and sources of the hot spring are studied by means of comprehensive application of geology,water chemistry and isotopes,which provid a scientific basis for the sustainable development and utilization of hot springs.The results show that the hot water is of HCO_3·CO_3-Na type.The hot spring can be used as a kind of medical hot mineral water that containing F and H_2S,but it should not be used as irrigation water.Isotopic compositions of hydrogen,oxygen and strontium indicate that the hot water is of meteoric origin,the supply area is a mountain area around 950 min the direction of the east and west parts of the hot spring.The geothermal water was formed by water-rock interactions.The corrected ~(14)C age using Person method is about 19 800 years.The temperature of the geothermal reservoir is about 82℃,and the circulation depth of the hot water is estimated as 1 900 m.The hot spring is formed by deep circulation of precipitation through the granite and heated by geoheat from the depth.
