利用地气场寻找隐伏温泉带——以广东暖水村为例

Using Geo-gas Field to Prospect the Concealed Hot Springs Zone-taking the Warm Water Village as an Example in Guangdong

随着国家对地热资源重视度越来越高,传统的物化探方法对于深部的隐伏温泉带勘查效果不佳,因此各领域地质专家纷纷提出新的勘查手段以加大隐伏温泉带的勘查深度。以重阳镇暖水村的温泉勘查为例,通过地气法测得30多种微量元素;并对之进行聚类分析,求得其异常指示元素,并进行稀土元素分析,利用地气指示元素的地气异常场对隐伏温泉带进行预测。结果表明:地气异常场圈定的温泉带中,有多处高达50℃的泉眼出露;稀土元素的分析结果也证实了地气异常场圈定的高温温泉带有利于稀土元素Ce的富集;并预测在3号测线的地气异常高值点(断裂带)附近仍有高温隐伏温泉存在;证明了地气场对于深部隐伏温泉的勘查是十分有效的手段。

As the state attaches great importance to the degree of geothermal resources is higher and higher,the effect of traditional physicochemical exploration for deep concealed hot springs is not useful. So every field geology experts put forward a new exploration method to extend the exploration depth of the concealed hot springs. The exploration of chongyang town warm water village was taken as an example,through the geo-gas sampling method measured 30 kinds of trace elements,combined with the cluster analysis and REE analysis to forecast the concealed hot springs. The result shows： 1 There are some points up to 50 ℃ hot springs discovered during the geo-gas field zone; 2 The results of the analysis of rare earth elements have confirmed the geo-gas field zone have advantage to the enrichment of rare element Ce; 3 There may be a high temperature concealed hot spring point exist in the selected the third line geo-gas field zone; 4 The geo-gas method is a very effective way to prospect the deep concealed hot springs.
