摘　　要：青藏高原大幅隆升为西藏盐湖和盐湖矿产的形成创造了极为有利的气候条件、地貌条件、地质构造条件。西藏地区Li、B、Rb、Cs等成盐元素区域地球化学背景值高,富含Li、B、Rb、Cs等的温泉广泛分布,为该区成盐元素大量聚集提供了充足的成矿物质来源,是我国寻找Li、B、Rb、Cs战略性新兴矿产的重要产地。对西藏Li、B、Rb、Cs盐湖矿产的成矿溶液和成矿物质来源,以及时空分布规律、成矿控矿条件、化学组分及相关性等进行了分析研究,系统总结了成矿规律和找矿标志。基于古大湖演化成盐模式,建立了锂硼铷铯盐湖矿产遥感综合找矿模型,在西藏全区圈定出181个Li、B、Rb、Cs找矿靶区,其中经验证新发现7处盐类矿产地,包括2处超大型铯、大型锂硼综合性矿床,1处大型锂矿床和4处中小型锂硼综合性矿床。The dramatic uplift of the Qinghai-Tibet Plateau has created extremely favorable climatic,geomorphic and geological conditions for the formation of salt lakes and salt lake minerals in Tibet.The geochemical background values of Li,B,Rb,Cs and other salt-forming elements in Tibet are high,and the hot springs rich in Li,B,Rb,Cs and so on are widely distributed,which provide sufficient metallogenic material sources for the large accumulation of salt-forming elements in this area,and are an important source for China to search for Li,B,Rb,Cs and other strategic emerging minerals.The source of ore-forming solution and ore-forming material,as well as the temporal and spatial distribution,ore-forming and ore-controlling conditions,chemical components and correlation of Li,B,Rb and Cs salt lake minerals in Tibet were analyzed and studied.Based on the salt evolution model of the ancient great lake,a comprehensive remote sensing prospecting model of rubidium and cesium Liborate salt lake was established.181 Li,B,Rb and Cs prospecting target areas were delineated in Tiebet,among which 7 new salt deposits were confirmed,including 2 super-large cesium and large lithium and boron complex deposits,1 large lithium deposit and 4 medium and small lithium and boron complex deposits.
