一、问题的提出研究含盐系地层的演化过程及湖水的浓缩程度对于指导找钾工作是至关重要的。在我国的大部分含盐盆地中,含盐系地层都含有较多的碎屑沉积物,既有成层出现在石盐层之间的,也有零散分布于盐类沉积物之中的。在研究盐类沉积演化时,总是把这些产状不同、组成各异的碎屑沉积物怍为淡化的标志,碎屑物含量越高,湖水浓缩程度越低,反之,湖水浓缩程度就高。如果这些碎屑物是由水携带而来的,这样的认识是可信的。但这些碎屑物是否还有风搬运来的,如果有,将它作为淡化的标志,就会得出错误的结论。因此,搞清碎屑物的成 First, the problem proposed Research Saline stratigraphic evolution and the degree of lake water concentration for guiding the search for the work of potassium is essential. In most of China’s salt basins, salt-bearing strata contain more detrital sediments, both stratigraphic in the rock salt layer, but also scattered in the salt sediments. In the study of salt sedimentary evolution, always these different shapes, the composition of different clastic sediments 淡 as a sign of desalination, the higher the detritus content, the lower the degree of lake water enrichment, on the contrary, the degree of lake enrichment is high . If these detritus are carried by water, such an understanding is credible. However, if these detritus are still carried by the wind, if there are signs of desalination, it will lead to the wrong conclusion. Therefore, find out the debris into
