摘要
This paper analyzes heat source,water source and the geological structures by studying field geological work, geological interpretation of remote sensing data and tectonic in front of Longmen Mountains in Guang Yuan area. The heat source is regarded as that the groundwater heated by itself deep circulation. There are no other heat sources. The water source is precipitation. There is thermal source due to the water heated by deep circle. At the normal regional background,geothermal circulation system-low medium temperature convective type geothermal system appears in the fractured media developed of deep carbonate rock,which has good potential for exploration and exploitation.
