英文摘要	Tuotuohe Basin, one of sedimentary basins in Qinghai-Tibet Plateau, has a large number of salt lakes, and these salt lakes are typically rich in boron, lithium and other rare elements. The origin and extent of these resources is still unknown. In this study, we present a detailed analysis of several chemical compositions (Na/Cl, B/Cl, B/Li and Br/Cl molar ratios) d(11)B and d(37)Cl characteristics of salt lakes in the Tuotuohe Basin. The evidences of d(11)B and d(37)Cl have proved that the salt lakes in the Tuotuohe Basin are a type of leached brine. The amount of B isotopes in the water of these lakes is in the range of +0.17%o to +12.52%o, suggesting that the salt lakes have a terrestrial origin. d(37)Cl and Cl/Br relations suggest that brines in Tuotuohe Basin belong to halite dissolving and also influenced by rainwater and the leaching of volcanic rocks during the evolution process. The characteristics of the d(11)B-B relationship are similar to those observed in the Tibetan geothermal area, indicating that these 2 places have the same B sources. Moreover, they have a crustal origin (Marine carbonate rocks and volcanic rocks) instead of a deep mantle source.
