Discussion on Some Problems Relating to Sedimentology and Stratigraphy
-
摘要: 本文简要地讨论了当前沉积学、层序地层学、旋回地层学以及与传统的岩石地层和生物地层有关的一些基本问题及彼此的关系。强调了沉积学原理在地层层序划分工作中的作用。将层序界面划分为四种类型,提出应以岩相突变面作为层序的界面。结合沉积学原理,指出层序是由岩相突变面控制的在一个较大的相对海平面升降周期中形成的一套有成因联系的岩石序列。在进行地层层序研究中,要注意层序地层、旋回地层与传统的岩石地层、生物地层的相互结合与借鉴。Abstract: Relations between sedimentology and stratigraphy, sedimentology and sequence stratigraphy, sequence stratigraphy and cyclostratigraphy are discussed with the principles of sedimentology being highly emphasized. Four types of equence boundaries are recognized. Hence, a sequence is defined as a series of genetically closely related sedimentary rocks formed in a longterm (third-or forth-order) transgrassive-regrassive cycle. Any rock surface between two different lithofacies which represent two slow long-term different transgrassive-regrassive cycles can be regarded as the sequence boundary. Sequence, stratigraphy, cyclostratigraphy, lithostratigraphy, biostratigraphy and etc. must be crossreferred.
