济南平阴氡温泉水化学成分与同位素特征研究
|
摘要
在系统的分析济南平阴氡温泉水化学成分和同位素特征的基础上,结合当地地形和水文条件,研究了氡温泉水的起源和形成年龄,结果显示:济南平阴氡温泉水温为28.3℃,pH值为中性,水化学类型为Cl·SO_4-Na·Ca型,富含氡、锶、氟、锂、溴、偏硅酸、偏硼酸等微量元素,且含量均符合理(医)疗热矿泉水水质标准,其中氡含量特别高是该温泉的一个显著特点。氡温泉水的同位素测定资料显示,平阴氡温泉热水起源于大气降水,用氚及~(14)C法估算出的氡温泉水的表观年龄在15.81±2.17 ka。
Based on the systematic analysis of the chemical composition and isotopic characteristics of radon hot spring water in Pingyin, Jinan, combined with the local topography and hydrological conditions, the origin and age of radon hot spring water were studied. The results showed that the water temperature was 28.3℃. The pH value is neutral, and the water chemistry type isCl·SO_4-Na·Ca, which is rich in trace elements such as strontium, barium, fluorine, lithium, bromine, metasilicate, and metaboric acid, and the content is in line with the physiotherapy hot mineral water quality standard. Among them, the high content of radon is a remarkable feature of the hot spring.. The isotope determination data of radon hot spring water showed that thePingyin Hot Spring originated from atmospheric precipitation, and the apparent age of the hot spring water estimated by tritium and ~(14)C method was 15.81±2.17 ka.
