塔里木盆地复合盐层地层分布广，在不同构造的钻探中都钻遇盐层，盐层厚度一般几十米到几百米，岩性以盐岩与膏岩、泥岩、泥质粉砂岩等不等厚互层。

Considering principles of sedimentation geology, utilizing the premise that two sequential layers (eroded and underneath uneroded layers) enjoy approximate deposition speeds, we plot with residual thickness values and thickness values of underneath uneroded layer in cross sections. By analyzing the diagram, we can not only obtain the eroded thickness of strata, but also explain the original sedimental environment of the eroded strata and the later structural erosion causes.

介绍了4种解释模型，充分考虑了沉积地质学原理，利用相邻两层沉积速率相近这个前提条件，通过在纵剖面上对剥蚀层残余厚度及下伏未剥蚀层厚度值进行坐标投点，分析它们的图形分布规律，不仅可以量化求取剥蚀厚度值，还可以对剥蚀层的原始沉积环境及造成剥蚀的后期改造作用，做出重要的地质成因解释。
