本文研究了碎屑沉积物薄层粒度的分布特征与沉积水动力条件的关系。提出了在粒度分析中一些值得注意的问题。发现薄层的粒度分布在正态概率图上大多数只出现一个次总体,它在一些更薄的层理中尤为明显。
In this paper, the relationship between the distribution characteristics of sediment thin-layer size and hydrodynamic conditions is studied. Some notable problems in the granularity analysis are proposed. It is found that most of the normalized probability maps show only one sub-population of the particle size distribution of the thin layer, which is especially noticeable in some thinner layers.
