西台吉乃尔盐湖矿区地下卤水钾、镁、锂、硼的时空变化特征

Temporal and Spatial Variation Characteristics of K,Mg,B and Li of Underground Brine in West Taijinar Mining Area

分析了西台吉乃尔盐湖矿区地下卤水中K、Mg、B2O3、Li等4种组分的时空变化特征。结果表明,它们在矿区西北部表现出明显的高值且基本不随时间而变化,这很可能与该区域原始卤水成分有关。由于地表水对地下卤水的淡化作用,这些组分在南部或西南部表现为低值。观测时段的中后期,四种组分的变化较显著,显示出采卤活动对其变化产生了影响。B2O3的高值区主要呈NW-SE向带状分布,这似乎与该地区的构造背景密切相关。

Temporal and spatial variation characteristics of four useful components which are K, Mg, B2O3 and Li of underground brine in west Taijinar salt lake are analyzed. The results show that four useful components have obviously high values in the northwest part of the mining area because of their high contents in original brine. Lower values of the useful components are present in the south and southwest part because of surface water desalination. In middle and late stage of observation period, prominent variation of four components indicates the influence of mining activities. The NW - SE trend of high value area of B2O3 is seemingly related to tectonic background of west Taijinar salt lake area.
