通过统计西藏高原盐湖镁离子及锂离子质量浓度的水化学数据和镁锂离子质量浓度比值,绘制出西藏地区盐湖卤水锂离子质量浓度分布等值线图和镁锂离子质量浓度比值分布图,分析了西藏地区盐湖锂资源品位及品质在空间上的分布规律以及盐湖锂资源富集与其所处地质环境的关系。分析表明:西藏地区盐湖锂资源的分布呈现分带性特征,盐湖锂离子质量浓度可能受构造带的控制,碳酸盐型盐湖带的盐湖卤水镁锂离子质量浓度比值最低,高品质低镁锂比卤水盐湖和低镁锂比卤水盐湖集中分布在碳酸盐型盐湖带硫酸盐型盐湖带过渡区内。
通過統計西藏高原鹽湖鎂離子及鋰離子質量濃度的水化學數據和鎂鋰離子質量濃度比值,繪製齣西藏地區鹽湖滷水鋰離子質量濃度分佈等值線圖和鎂鋰離子質量濃度比值分佈圖,分析瞭西藏地區鹽湖鋰資源品位及品質在空間上的分佈規律以及鹽湖鋰資源富集與其所處地質環境的關繫。分析錶明:西藏地區鹽湖鋰資源的分佈呈現分帶性特徵,鹽湖鋰離子質量濃度可能受構造帶的控製,碳痠鹽型鹽湖帶的鹽湖滷水鎂鋰離子質量濃度比值最低,高品質低鎂鋰比滷水鹽湖和低鎂鋰比滷水鹽湖集中分佈在碳痠鹽型鹽湖帶硫痠鹽型鹽湖帶過渡區內。

Based on statistical data of the mass concentrations of Mg2+and Li+and the concentration ratio of Mg2+to Li+ in saline lakes in the Tibet Plateau, the isolines of the mass concentrations of Li+and the ratio of Mg2+to Li+in saline lake brines in Tibet were drawn. The spatial distribution pattern of the content and the quality of the lithium resources in saline lakes in Tibet and the relationships between the enrichment of lithium resources and the geological environment were analyzed. The distribution of lithium resources shows a zonation character. The concentration of Li+ in saline lakes is mainly influenced by the tectonic belt. The zone of carbonate saline lakes shows the lowest ratio of Mg2+to Li+, with the high-quality and general saline lake brines with low ratios of Mg2+to Li+ mainly distributed along the transition zone between the carbonate saline lakes and the sulfate saline lakes.
