内蒙伊克昭盟是我国现代碱湖分布最集中的地区．各碱湖矿层的主要盐类矿物是泡碱．其次是芒硝、天然碱和石盐及少量单斜钠钙石、氯碳钠镁石、钙水碱和水碱。泡碱普遍存在于各个碱湖的矿层中，芒硝主要存在于西部碱湖的矿层中．天然碱集中分布于碱湖区西南部的几个碱湖中．且只分布于矿层的某些部位。碱湖矿层剖面上，天然碱与芒硝呈互为消长关系．天然碱和石盐则呈正相关。
Inner Mongolia Yikezhao League is China’s most concentrated distribution of alkaline lake areas. The main salt mineral in each alkali lake is caffeine. Followed by Glauber’s salt, trona and stone salt and a small amount of monoclinic soda limestone, sodium bicarbonate, calcium and alkali. The caustic soda is commonly found in the caverns of all alkali lakes, and is mainly present in the caverns of western alkali lakes. Trona concentrated in the Alkali Lake in the southwest of a few alkaline lake. And only distributed in some parts of the mine. On the section of Caoyao mine, trona and mirabilite showed a reciprocal relationship. Trona and rock salt were positively correlated.
