摘要
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。
Modern soda lakes in China are distributed mainly in Ikejomong .Inner-Mongolia. Main salt minerals in mineral beds of every soda lake are natron. mirabilite, trona and halite with minor gaylussite, northupite, pirssonite and thermonatrlte. Natron is in common in mineral beds of soda lakes and mirabilite is presents mainly in mineral beds of western soda lakes. Trona is distributed mainly in several soda lakes of southwestern soda lake area and only in some sections of the mineral beds. Trona is negatively correlated with mirabilite in the mineral bed sections of soda lakes. Trona and halite show a positive correlation.
