摘 要: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。
Abstract: The relationship between the characteristics of the grain-size distribu-tions of thin beds for clastic sediment and the conditions of waterpower in deposition is studied in the article. Some questions which areworth noticing in sizing are raised. It is found that the grain-size distri-butions of thin beds mostly show one secondary population in the normalprobability diagram, which is, in particular, obviovs in some thinner beddings.
