| 摘 要： | 为查明济南平阴某氡地热井的补给来源,采用分析环境同位素的方法。先利用14 C定年,确定该氡泉水以古水为主;后利用同位素分析结果进行高程计算,确定出该氡地热井的补给来源标高为+140m,此结果与水文地质条件确定的补给区(泰山余脉标高+100m~+180m)位置一致,说明该氡地热井的补给来源为东南方向40~50km外的泰山余脉。

| Abstract: | In order to determine the recharge source of a radon geothermal well in Pingyin county of Jinan city, environmental isotope method has been used. First, by using 14C dating, it is determined that the radon spring is mainly composed of ancient water. Then, by using isotope analysis result, the elevation has been calculated, it is determined that the elevation of recharge source of radon geothermal well is +140m. The recharge area is the same as determined by hydrogeological conditions (the elevation of Taishan stretching Mountain is 100~180m). It is indicated that the recharge area of the radon geothermal wells is Taishan stretching Mountains southeast 40 ~ 50km away from there. |
