| 摘 要： | 识别盐构造对于研究盐体改造作用、钾盐成矿预测以及钾盐矿山的安全开采利用等方面具有重要作用。本文以老挝万象钾盐矿区为主要研究对象,分析了区域盐背斜成因并尝试构建识别标志。研究表明,重力异常分布可以指示和圈定盐背斜构造位置和分布特征,研究区盐背斜的形成与古河道切割具有密切的成因联系,盐背斜构造在地形地貌上具有明显的响应特征。上述研究结果对于深入认识该区域钾盐矿床的成因与后期改造作用过程具有重要意义。

| Abstract: | Identifying salt structures plays an important role in the study of salt reformation, potassium salt mineralization prediction, and safe mining and utilization of potassium salt mines. This paper takes the Vientiane potash mining area in Laos as the main research object, analyzes the origin of the regional salt anticline and tries to construct an identification mark. The research shows that the distribution of gravity anomalies can indicate and delineate the location and distribution characteristics of salt anticlines. The formation of salt anticlines in the study area is closely related to the cutting of paleochannels, and the salt anticlines have obvious topographical response characteristics. The above research results are of great significance for in-depth understanding of the genesis and later reformation process of potash deposits in this area. |
