| 中文摘要: |
| 硝口岩盐矿床位于六盘山盆地中南部，具有平面上分布范围较小，垂向上厚度巨大，沿走（倾）向变化大的特点；主要盐类矿物均见有原生沉积和后期充填两种类型。通过对硝口岩盐矿床构造、矿层、矿物、微量元素和稀土元素进行分析研究，认为硝口岩盐矿床成因为"高山深盆"成盐模式，属于典型的陆相硫酸盐—氯化物盐湖沉积；巨厚岩盐矿层的形成一是原始沉积厚度大，二是受构造影响间接使矿层"加厚"。 |
| 英文摘要: |
| The Xiaokou salt deposit is located in south central Liupanshan basin and characterized by small horizontal distribution and huge vertical thickness and great variation along strike or inclination. The main salt minerals are of primary sedimentation and later filling. By analysis of the structure, ore layer, minerals, trace elements and rare earth elements, the author thinks that the Xiaokou salt deposit is formed in high mountain deep basin model and belongs to the typical continent-faced sulfate-chloride sedimentation lake. The huge thickness is resulted from the original thick sediment and the structural thickening. |
