在研究分析西藏续迈地热田深部地球物理探测成果基础上,以音频大地电磁测深 ( AMT) 和大 地电磁测深 ( MT) 成果为依据,认为盆地东侧隐伏的深大构造是 “热水河”的深部热源通道,由其 将深部地热流体运移至浅部,并贮存于浅部破碎带和第四系内; 而后,在地应力作用下热水沿次级断 裂构造溢出地表,并与地表沼泽冷水混合,形成 “热水河”｡ 

Based on the results of the deep geophysical exploration ( i. e.,audio frequency magnetotelluric sounding and magnetotelluric sounding) in the Xumai geothermal field,the authors consider that the buried deep structure on the east side of the basin is the deep heat source channel of the“hot river”,by which the deep geothermal fluid was transported to the shallow part and stored in the shallow fracture zone and Quaternary strata. Then,the hot water overflowed the surface along the secondary fault structure and mixed with the cold water from the surface to form a“hot river”.
