摘要: 本文系根据1980年全国碎屑岩沉积相模式和相标志讨论会的分组总结并参考国内、外研究现状写成的.文中首先谈到沉积相模式的研究在科研和生产上的重要意义,沉积环境、沉积相和沉积相模式的含义,以及鉴别沉积相的主要相标志类型.然后针对我国地层中经常见到的河流相、湖泊相、浊流相、三角洲相、海滩相和潮坪相,以及相标志中的层理进行较详细的阐述.

Abstract: This paper is prepared from the proceedings of the national conference in 1980 for the discussion of patterns of sedimentary facies and facies characteristics of elastics,also in reference to the present status of study of the subject at home and abroad,It first deals with the significance of the study in research work,the implications of depositionat environment,sedimentary facies and patterns of sedimentary facies and the principal characteristics for identification of sedimentary facies;followed by a more detailed account of the six sedimentary facies of common occurrence in China.the fluviatile facies,the lacustrine facies,the turbidite facies,the deltaic facies,the littoral facies and the tidal facies.Mention is also made of stratification which is an important aspect of sedimentation.In the light of hydrodynamics,the forms of channel sands under different hydrodynamic conditions and the types of resulting stratification are examined.A classification of cross-beddings is made on the basis of the size of formation.A review is also made of the history of research done abroad on the six types of sedimentary facies as well as the present status of our research,besides dealing with the mechanism of formation,classification and distinctive features of each facies.
