| 摘 要： | 东台吉乃尔盐湖经过长期的成盐演化和成矿过程 ,最终形成了以氯化钠化学沉积为主的蒸发盐 ,晶间卤水富含B、Li等多种元素卤水矿床 ,根据 1998年对该湖干盐滩中部所打的CK1孔钻孔剖面( 12m)及测试的几个14 C年龄 ,初步证实该盐湖上部盐层是在约 10 0 0 0aBP形成 ,未经碳酸盐和硫酸盐成盐阶段 ,盐湖形成初期即进入氯化物成盐阶段。

| Abstract: | Based on facts of the CK1 drilling and data of 14C age in Dongtaijineier Salt Lake,the deposit characters,the ancient climate ,the deposition environment and the ages of the salt deposits were studied in the region of the salt lake.As some results,the most contents of the salt sediments is NaCl,the salt deposition has been formed since the time about 10 thousands of years ago.The ancient climate was very dry. |

| Keywords: | chloride deposition environment 14C age brine with boron and lithium Chaidamu Basin of Qinghai province |
