摘要: 西藏地热系统中发现地热流体稀碱金属含量的世界最高值以及喜马拉雅地热带最大水热系统羊八井地热田的稀碱金属测定,为研究全球唯一陆壳相聚超厚地壳上喜马拉雅地热带的特殊热源机制提供了令人信服的地球化学依据。羊八井电厂热排水回收稀碱金属也为综合利用地热流体,消除环境污染,提高电厂经济效益创造了不可多得的机遇和方案选择。

Abstract: The world's highest values of geothermal fluid rare-alkali metal contents discovered in Tibetan geothermal systems and the rare-alkali metal determination of the Yangbajing geothermal field, the largest hydrothermal system in the Himalayan geothermal belt, offer convincing geo-chemical evidence for the study of the mechanism of the specific heat origins of the Himalayan geothermal belt located on the sole global continental crust convergence zone with the greatest crust thickness. The reclaim of the rare-alkali metal from the thermal discharge of the Yangbajing power plant also creates unique opportunities and options for the comprehensive utilization of geothermal fluids, the elimination of environmental pollution, and the enhancement of economic benefits.

Key words: rare-alkali metal, the Himalayan geothermal belt, geochemical evidence
