本文通过对开平盆地杨庄组泥(页)岩状岩石酸不溶物中砂、泥含量的统计,明确其正确命名应为泥云(灰)岩。本文将杨庄组分为三段,即3.红白相间厚互层泥岩状含砂泥云(灰)岩段、2.红白相间薄互层页岩状泥灰(云)岩段、1.白云岩发育段。本文指出杨庄上升在本区确有表现,但这一运动的剥蚀强度较小,剥蚀深度也仅限于高四段。 Based on the statistics of the content of sand and mud in the acid-insoluble rock in the Yanzhuang Formation of the Yangping Formation in the Kaiping Basin, it is clear that the correct nomenclature should be muddy cloud (gray) rock. In this paper, the Yangzhuang Formation is divided into three sections, namely, red-white and white-thick interbedded mudstone-like mudstone cloud (gray) rock section, red-white and thin interbed shale- 1. Dolomite development segment. This paper points out that the rise of Yangzhuang does show in this area, but the denuded intensity of this movement is smaller and the depth of denudation is only limited to the upper four sections.
