| 摘 要： | 四川盆地早中三叠统蒸发岩极为发育,时空分布甚广。蒸发岩的生成模式可分为两大类和四个亚类。即Ⅰ,潮间环境的为(1)泻湖盐湖;Ⅱ,潮上环境的为(2)滨海盐湖;(3)近岸盐湖和(4)远岸盐湖。不同生成模式中,其成盐机理虽对成钾皆不够理想,但仍有希望找到钾盐矿的地区和层段。

| Abstract: | the evaporite of lower-middle Triassic is extremely rich and widely distributed in Sichuan Basin.It can be divided into two classes and four subclasses,namely,I,intertidal environment,being(1) lagoon salt lake,II,uppertidal environment,being(2) coastal salt lake,(3) nearshore salt lake and(4) far offshore salt lake.Although the saltforming mechanisms are not ideal for the formation of leopoldite,there are still chances to find the leopoldite stratum or zone. |
