Characteristics and source mechanism of geothermal field in Cuona, Tibet
Abstract
Cuona county is located in the south of shannan region of Tibet and the middle of the Himalayas, which is an important border port in China. To study the characteristics and source mechanism of geothermal field in Cuona, we use hydrochemical meathods such as piper and Gibbs to analyze the hydrogeochemical characteristics and main material sources of the hot springs water with geothermal geological conditions. The temperature of reservoir in the research area is calculated by geothermometers and graphic method of multi-mineral balance after a detailed introduction of the principles of several methods.The comprehensive analysis results indicate that the geothermal reservoir temperature is about 117℃ and the study area is of HCO3-Na type. The next step is to evaluate the resources. The research work we have done can identify main material sources and resources, provide technical support for the development and utilization of geothermal resources, meanwhile, promote ecological environmental protection and change energy structure in this region.
