摘要

河西走廊属于大陆板块内部的活动带,该区活动断裂发育,地震活动比较频繁,并有巨厚的中新生代沉积盆地,有较好的地下热水资源赋存的地质构造背景。从该地区的热源、水源及构造条件入手,对地下热水资源的成因类型进行深入的分析,认为地下热水系统的主要成因类型为中新生代断陷—坳陷盆地传导型和断裂带所控制的深循环对流型。为河西走廊地热资源的勘探和开发提供依据。
Hexi Corridor is located in active faults of the inner continental plate.With well-developed active faults,very active earthquakes and large-thickness Meso-Cenozoic sedimentary basin,it owns the geologic structure background on which geothermal water exists.The paper,through studying on its heat source,the source of water and the tectonic conditions,analyzes a few types of formation cause of geothermal water resources,and considers that the major types of geothermal water system are Meso-Cenozoic fault-depression basin transmission type and deep circulation convection type controlled by fault zone.The conclusion will provide scientific bases for the exploitation and development of geothermal water resources in Hexi Corridor.
