| 摘 要： | 贵州东南部下寒武统发育较为完整,相变剧烈,组成总体向上变浅的沉积序列,该序列代表一个二级层序;该二级层序还可以进一步划分为5个三级层序。自北西向南东,随着从斜坡到盆地的沉积背景变化,下寒武统逐渐变薄,直至变为一个难以进行三级层序划分的凝缩作用序列。依据三级层序空间上相序的有序性和时间上环境变化的同步性,以地层记录中两种相变面和两种穿时性为基本要素建立研究区下寒武统层序地层格架,该格架表明了在寒武纪早期的快速海侵所造成的台地淹没事件之后,所形成的特殊的三级沉积序列样式。

| Abstract: | Lower Cambrian strata are quite completely developed in southeast Guizhou,and the transitional facies characterized by intense facies change comprise an upward shallowing sedimentary succession,which constitutes a second-order sequence.This second-order sequence can be further divided into five third-order sequences.From northwest to southeast,with the change of sedimentary setting from slope to basin,Lower Cambrian strata gradually thin and eventually form a condensed succession which is difficult to divid... |
