内蒙古西部盐碱矿地质特征浅析——以阿拉善左旗某芒硝、湖盐矿为例

Geological characteristics and genesis of saline-alkali ore in western Inner Mongolia——Take the Glauberite and lake salt mine in Tulantai Salt Lake of Alashan Left Banner as an example

研究区内芒硝、湖盐矿层赋存于第四系全新统地层之中,位于湖区中部化学沉积区。芒硝矿层2层,呈似层状、透镜状,产状水平,长250m~3010m,宽170m~2950m,厚度0.10m~1.34m,平均厚0.32m。湖盐矿层1层,呈似层状、透镜状,产状水平,长3250m,宽1870m,厚度0.20m~1.34m,平均厚0.48m。

The research area is located in the southwest of Alxa Left Banner,Inner Mongolia.It is under the jurisdiction of Alxa Left Banner,Erke Hashi Hasu Tulantegacha.Mirabilite and lake salt deposits are located in the holocene quaternary strata in the middle of the lake area.The 2 layers of Glauber's salt ore are layered,lens-like,horizontal,250m~3010m long,170m~2950m wide,0.10m~1.34m thick and 0.32m thick on average.The lake salt deposit has one layer,which is stratified,lenticular and horizontal,3250m long,1870m wide,0.20m~1.34m thick and 0.48m thick on average.
