摘　　要：研究区处于喀喇昆仑居里等温面隆起区,新生代岩浆活动剧烈,热流值高,地震测深显示在地壳内存在低阻、低速层。相继在俘虏沟、红山湖、苦水湖一带发现多处地表热泉沉积物——泉华,对比青藏高原典型钙华岩石化学特征,具有一致的主量元素分布特征,相近的微量元素和稀土元素配分模式,暗示其可能为同一时代的产物。研究成果显示,大量水热活动与能量的产生,伴随泉华的沉积和相关矿物与流体的产出,可形成Li,B,Cs,Rb,Br,I,Zn,Au,Ag,Pb,He等多种矿产。泉华作为水热活动在地表的产物,泉华群的分布和水热活动区的分布格局基本一致。泉华群的集中出现,展现了研究区内寻找干热岩的巨大前景。钙华作为古气候环境的重要载体,利用热水钙华重建古环境的研究具重要意义。The study area is located in the Curie point isothern uplift area of Karakoram.The Cenozoic magmatic activity is intense and the heat flow value is high.The seismic sounding shows that there are low-resistivity and low-velocity layers in the crust.A number of surface Sinter deposit have been found successively in the areas of Fulugou,Hongshanh and Kushuih.Comparing the chemical characteristics of typical calc-sinter in the Tibitan Plateau,they have the same distribution characteristics of major elements and similar distribution patterns of trace elements and rare earth elements,suggesting that they may be the products of the same era.The research results show that a large number of hydrothermal activities and energy generation,along with the deposition of Sinter deposit and the output of related minerals and fluids,can form Li,B,Cs,Rb,Br,I,Zn,Au,Ag,Pb,Zn,He and other minerals.As a product of hydrothermal activity on the surface,the distribution pattern of the sinter Group is basically the same as that of the hydrothermal activity area.The concentrated occurrence of sinter Group shows the great prospect of searching hot and dry rocks in the study area.As an important carrier of paleoclimate environment,the study of using hot water travertine to reconstruct paleoclimate environment is of great significance.
