摘要
本文详细描述了辽东半岛寒武系的剖面,将剖面划分为碱厂组、馒头组、毛庄组、徐庄组、张夏组、崮山组、长山组、凤山组等8个岩石地层单位,并进行了地层对比,使研究区寒武纪的岩石地层、生物地层和层序地层得到了统一。根据沉积相岩石的岩性和化石带的分布等特征,能更好地了解层序岩相古地理展布和沉积演化,可以有效地恢复辽东半岛寒武纪时期的气候变化和环境变迁。
This paper depicts in detail the Cambrian profile in east Liaoning peninsula, divides it into eight stratum units upwards including Jianchang, Mantou, Maozhuang, Xuzhuang, Zhangxia, Gushan, Changshan and Fengshan formations, and compares them, thus unifying the lithological sequence, paleontological sequence and stratigraphic sequence. The paleographic spreading and sedimentary evolution of stratigraphic sequences can be well studied based on the lithology of sedimentary rocks and fossil distribution, providing a useful tool in recuperating the climatic and environmental changes in Liaoning peninsula.
