| 摘 要： | 鲁西地区寒武纪地层与华北地台一样，属稳定克拉通陆表海沉积，其三级层序明显由若干个次级层序复合而成。根据苍山、新泰、长清等地露头层序地层学的研究，可将鲁西寒武纪地层划分为１６ 个三级层序，每一层序均表现为向上变浅的进积序列，底部常以沉积间断面为界，顶部见有暴露标志。通过对构成层序的三个基本要素的分析，探讨了相应的海平面变化。

| Abstract: | The same as Huabei platform, Cambrian strata in west of Shandong belong to stable crator epicontinental deposits. Its third-grade sequences are composed of many secondary sequences evidently. According to the study on the outcrop sequence stratigraphy in Cangshan, Xintai and Changqing, Cambrian strata in west of Shandong can be divided into 16 secondary sequences, and each possess the characteristics which become shallow upwards. There are a breaking boundary at the bottom, and exposure sign can be seen at the top. In addition, on the basis of analysis of three basic elements which consisted of the sequences, sea-level variations related are also disscussed. |
