西藏高原地热活动,温泉分布与地球物理场特征

本文根据西藏高原地热活动与温泉分布和各种地球物理场的特征,进行了综合分析与研究,给出了地壳深部要素的统一解释。说明了西藏高原水热分布及其活动原因是由于地壳介质中温度很高,地壳中存在着物质的熔融或部分熔融所致。水热显示是受深部地壳构造与物质运移所制约,其热能是由印度板块与欧亚板块碰撞过程中所产生的热量和岩浆上涌所提供的。

CHARACTERISTICS OF GEOTHERMAL DISTRIBUTION AND GEOPHYSICAL FIELD OF XIZANG PLATEAU

The Xizang Plateau is the most intense area for geothermal activities in our country the crustal structure is very complex and earthquake activities are extremely frequent.Based on geothermal data and various features of geophysical fields in the region research and analyses has been made in this paper. A unified interpretion of the nature in the deep part of the crust is given. It indicates that the cause of geothermal distribution and its activity in Xizang Plateau is due to the high temperature in the crustal medium and the existence of melting or partial melting matter in the crust. The geothermal display is affected by the deep crustal structure and material migration and the geothermal energy is provided by the quantity of heat produced by the collision process of the Indian plate against the Eurasian plate and the magmatic intrusion.
