Research on the Relationship between Geothermal Field and the Tectonic in Himalayas and its Surrounding Regions

In this article,based on the terrestrial heat flow data, the terrestrial heat flow map in the area, geothermal gradient map and different depth geothermal contour map of study area within the Territory of China, I explored respectively the relationship between geothermal field and tectonic, geologic structures by analyzing respectively the corresponding relationships between the structural diagram and terrestrial heat flow diagram, temperature contour map, geothermal gradient map in study area. The main conclusions are as follows. Geothermal field has been restricted by the India plate and Eurasian plate collision. So the study area as a whole is a geothermal abnormal area. Features of regional geological structure control the geothermal flow distribution. Geothermal abrupt changing occurs between different tectonic units.
