| 摘 要： | 干盐湖蒸发岩沉积是干旱内陆封闭盆地的主要成盐模式,其地表盐壳沉积特征、蒸发盐类矿物具有明显的分带性.罗布泊干盐湖,保存了完整的"耳轮"型环状沉积模式和演化序列,在世界干盐湖中实属罕见.通过对罗布泊"大耳朵"干盐湖区多级环状亚沉积环境下发育的盐壳地貌、沉积结构、龟裂形态、矿物组成以及地下卤水的地表排泄情况进行地面调查和实...

| Abstract: | The majority of present-day evaporite deposition occurs in arid closed continental basins in which the playa lake is most common.The distribution of evaporite minerals and sedimentary features of salt crust are usually zonal in a playa lake.The integrated zonal configuration is preserved well in the Lop Nor playa,which is represented by a series of concentric rings that closely resemble a great human ear in satellite images.This type of natural phenomenon is very rarely seen in a playa lake.The Lop Nor basi... |
