Abstract: Geothermometry of the Xitieshan-Golmud-Yadong profile in Qinghai-Tibet Plateau shows that the highest temperature is found in the northern Chadum Basin and the geothermal temperature of the massifs in the Qinghai-Tibet Plateau has an increasing tendency from north to south. In the Plateau, the temperature of the Lahsa-Gangdisi massif is the highest, the Himalayas massif comes next, and then the Qiangtang, Kekexili-Bayankela and the Kunlun massif. The geothermometry measurements coincide well with the division of each massif and the fault boundaries. Temperature at the faults is obviously higher than the adjacent massifs, and the temperature at the Shiquanhe-Yalu Tsangpo River fault is the highest. The research on the geothermal state of the Qinghai-Tibet Plateau lays an important foundation for the study of geothermal dynamics in the Qinghai-Tibet Plateau.
