新疆地下热水特征及其与地震活动的关系

A STUDY OF UNDERGROUND HOT WATER OF XINJIANG IN RELATION TO EARTHQUAKES

新疆地下热水广泛分布于昆仑山、天山和阿尔泰山。温泉和地震活动与大地构造、板块运动有着密切的联系。动态观测资料分析表明，热水温度变化不仅受到地震的作用，而且显示出某些地震前兆信息。分析了地下热水的化学成分、气体组分、微量元素、放射性元素，认为某些热水具有低矿化、高碱性、高氟、高氦等独特性质，有可能是形成于地壳深部或上地幔的深成水。

Underground hot water occurs widely in the Kunlun, Tianshan and Artai mountains of Xinjiang. Hot spring, seismicity, tectonics and plate movement are closely related to each other. Analyses of the dynamic observational data show that changes of hot water temperature is influnced by earthquakes and indicates precursors to these events. Chemical analyses have been made to the underground hot water. It is suggested that some hot water have the special nature of low mineralization, high alkalinity, high fluorine and high helium. It may be the inner original water fomed in the deep crust or upper mantle wich is of importance to the study of inner materials and processes of the Earth.
