Abstract: |
The salt lakes over Qinghai-Xizang Plateau is characterized by large numbers, wide distribution, complete types, rich and important natural resources in China.Except large amount of carbonate, sulpfiate, borate and chloride deposits, there are brine resources, rich in trace elements and dispersed elements, especially Li,B,Mg.The high grade,great reserves of trace elements have taken the dominate position in salt lake resources in China, and is also rarely seen in other salt lakes in the world.There are various kinds of salt lake resources over Qinghai-Xizang Plateau, for example, solid salt deposits, saline brines, inorganic salt deposits and also various salt lake bio-resources.Halite, mirabilite, trona, carnallite, bischofite, sylvite, antarcticite, celestite, borates (borax, ulexite, pinnoite, kurnakovite) have formed sedimentary deposits of different sizes for direct utilization.Besides, there are saline brines, rich in K, Mg, B, Li, Rb, Cs, U, Th for comprehensive use.In some salt lakes like Dongcuo, Gahai, there are many kinds of halobionts which may be used as a new kind of salt lake resources in the future. |
