讨论了露头层序地层学研究的几个基本理论问题 ,认为详细的沉积相分析和副层序叠置样式的研究、生物地层研究、不同地区和不同沉积相区的对比研究是正确划分层序的必要基础 ;初始海泛面是露头层序地层学研究中理想的层序界线 ,不仅在野外露头上最容易识别 ,还使层序及层序界面的年代可以用生物地层精确标定 ;把空间分布范围 ,特别是在不同沉积相区的分布 ,作为定义和识别各种级别层序的一个标准 .三级层序至少应可以在同一大陆边缘的不同相区辨认 ,有些甚至可以进行全球对比 ;应用层序地层优化年代地层单元界线 ,在地球演化自然节律基础上建立新一代地质年表 ,应使用初始海泛面作为界线的主要辅助标志 .
Several basic theoretical problems of outcrop sequence stratigraphy research are discussed. It is considered that the detailed study of sedimentary facies analysis and secondary sequence superimposition pattern, the study of bio-stratigraphy, the comparative study of different regions and different sedimentary facies zones are the proper demarcation of sequence The initial sea surface is the ideal sequence boundary in the study of outcrop sequence stratigraphy. It not only can be easily identified in the outcrop of the outcrop, but also can be used to accurately calibrate the age of sequence and sequence boundaries with the biological strata. Distributions, especially in different sedimentary facies zones, serve as a criterion for the definition and identification of sequences at various levels, which should at least be identifiable in different zones of the same continental margin and some may even be globally comparable; Using sequence stratigraphy to optimize boundaries of stratigraphic units and establishing a new generation of geochronology based on the natural rhythm of the Earth’s evolution, the initial sea surface should be used as the main auxiliary marker.
