摘　　要：阿根廷奥布莱莫埃尔多盐湖位于南美安第斯高原“锂三角”地区,钾锂资源丰富;为了研究该盐湖卤水特征,分析其钾锂资源远景,利用遥感数据提取钾、锂异常信息,并在湖区施工浅井采集卤水样品进行验证。盐湖钾锂一般赋存于含盐细砂中,靠近盐湖中部赋存于石盐为主的盐类矿物晶体间的孔隙之中;卤水分析结果表明,KCl含量0.60%~2.11%,平均品位1.03%,LiCl含量146~4977mg/L,平均含量2407mg/L;遥感解译显示湖区存在高矿化度卤水,钾锂异常主要集中分布于湖区岛屿北部、东北部及南部靠近岛屿地带。奥布莱莫埃尔多盐湖遥感信息显示钾、锂异常,浅井卤水分析富含锂钾,部分样品达到工业品位,盐湖找矿潜力巨大。Hombre Muerto Salt Lake in Argentina is located in the"lithium triangle"area of the Andes plateau in South America;In order to study the brine characteristics of Hombre Muerto salt lake in Argentina,In the construction of shallow wells in the salt lake,brine samples were collected and analyzed,The remote sensing data were used to extract the abnormal information of potassium and lithium,and the prospect of potassium and lithium resources was analyzed.The saline lake lithium-potassium salt generally occurs in the fine sand,the salt mineral crystals near the central saline lake located in the pores between halite.The result of brine analysis showed that the content of KCl was 0.6%-2.11%,the average grade was 1.03%,and the content of Li was 146-4977 mg/L,with an average content of 2407mg/L.The remote sensing interpretation shows that there is high mineralization of brine in the lake area,and the potassium and lithium anomaly are mainly concentrated in the northern,northeastern and southern islands of the lake area.Hombre Muerto salt lake of remote sensing information display abnormal potassium,lithium,shallow wells are rich in potassium-lithium brine analysis,some samples to industrial grade,the salt lake area is large,the prospecting potential is tremendous.
