Simulated Experiment of the Geothermal Resources Exploration in Tangli Hot Spring, Wuning, Jiangxi Province, China

The geogas field can reflect the deep-seated tectonic constructing information. Geogas method can be applied to the exploration of deep geothermal resources. In this paper, based on the advanced geogas model of metal ore, a set of simulation model of geogas transportation for hot spring is built. In the model, hot spring water collected from Wuning, JiangXi province, China is used to simulate hot spring reservoir, and the hot air flow formed by electric hot plate is used to simulate rising geogas flow. The transporting materials from hot spring reservoir are sampled in 20, 40, 60, 80 and 100 d respectively. More than 30 elements in these samples are determined with ICP-MS. The experimental results confirm that many elements in hot spring can be transferred out by geogas flow, transportation rate and transportation ratio of different elements is of obvious differences. The migratory activity of most elements in hot spring is greater than that in concealed ore body, thus the transportation amount of the element is easily recognizable. The elements with high transportation ratio and high concentration, including Cd, Cu, Pb, Sc, Y, Zn, are most helpful to indicate towards hot springs, the result provides reference to application of geogas survey on geothermal resource exploration.
