【摘要】 中国西藏高原地热活动强烈,喜马拉雅地带是一条走向近东西向延伸的地热带。这里没有近代火山活动,但却具有水热爆炸、间歇喷泉、沸泉和种类繁多的热泉及温泉等典型的近代火山活动地带的特色。 根据喜马拉雅地热带的分布,水热地球化学与其活动特征、地质构造与地球物理场背景等说明这种地热活动具有板块边缘的特征,它是印度板块早期俯冲与两大陆板块近期持续碰撞与挤压作用下的结果。反映了大陆板块碰撞挤压过渡带的水热活动标志。更多还原

【Abstract】 China’s Tibetan Plateau experiences strong gcothermal activities.The Himalayan region is itself a geothermal zone atrikiag nearly east-west.Although there are no contemporary volcanic activities there,yet hydrotliermal explosions,geysers,boiling springs and many other kinds of hot springs,typical features of modern volcanic activities,are commonly found in there.The distribution of the Himalayan geothermal zone,characteristics of hydro-thermal and geochemical activities,geologic strucure and geophysical background etc.all show such geothermal activies are characterized by features of plate margins.It is the outcome of the early underthrusting of the Indian plate and recent and successive collision and compression of the two continental plates.This is the manifestation of typical symbols of liydrotherrnal activities in the transition zone of collision and compression between continental plates.更多还原
