哈密大洼地一带钾盐矿水文地质及水化学特征分析
|
摘要
研究区位于罗布泊盐湖东北部,库鲁克塔格山(白山)北部,磁海石英滩丘陵区南部,地理坐标:东经93°43′29″;北纬41°05′41″,是地下水的最终排泄地。主要接受南、北部山前基岩裂隙水、东侧季节性迳流补给,以承压水西侧地下径流的方式排泄,地下水含盐量较高,一般均为卤水,矿化度在20g/l以上。属现代内陆盐湖液相的硫酸盐型综合矿床,为地下卤水钾盐矿床。
The study area is located in the northeast of Lop Nur Salt Lake, north of Kuruktag Mountain(Baishan) and south of the quartz beach hilly area of the magnetic sea. Its geographic coordinates are 93 43 29 in the east longitude and41 05 41 in the North latitude. It is the final discharge area of groundwater. It mainly receives fissure water from piedmont bedrock in South and North and seasonal runoff from east. It is discharged by underground runoff from west side of confined water. The salt content of groundwater is high, generally brine, and the salinity is above 20 g/l. It belongs to the sulfate type comprehensive deposit of modern inland salt lake liquid phase, and is an underground brine potassium salt deposit.
