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 theSconcealed hot springs. In this paper, the writerStake the exploration of chongyang town warm water village 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.
