摘要： 近年来,在《古地理学报》(中文版和英文版)的已刊文章和来稿中,一些作者把岩石或岩石类型称作“微相”或“岩相”,把岩石薄片中的微观特征称作“微相”,把岩石的宏观特征称作“宏观相”。笔者曾写过2篇中文的短文《主编的话——岩石不是微相》和《主编的话——岩石不是岩相》,刊于《古地理学报》(中文版)中。但是此二文尚未引起国内外广大读者的关注。还有,在20世纪80年代,一些中国沉积学家根据野外露头和钻井岩心的岩石宏观特征,提出了“亚相”和“微相”。这个“微相”的定义与外国沉积学家在20世纪40年代根据岩石的显微镜下微观特征提出的“微相”的定义完全不同。这些问题屡屡出现从而迫使笔者,作为《古地理学报》(中文版和英文版)的主编,应该遵循“百花齐放和百家争鸣”的方针,再写出1篇中文及英文兼有的新文章,即《沉积相的一些术语定义的评论》(A review on the definitions of terms of sedimentary facies),把沉积相的一些术语,如“相”、“沉积相”、“岩相”、两种“微相”、“宏观相”、“亚相”等术语的定义讲清楚,并把此文同时在《古地理学报》(中文版和英文版)中刊出。希此文能引起国内外广大读者的关注,并撰写文章和参与这些问题讨论及争鸣,争取逐步得到一些共识,从而促进沉积学和古地理学的进步与发展。

Abstract: In recent years,in some papers published in and manuscripts submitted to the Journal of Palaeogeography(Chinese Edition and English Edition),the authors named rocks or rock types as “microfacies”or “lithofacies”,named the microfeatures in thin-sections under microscope as “microfacies”,and named the macrofeatures of rocks as “macrofacies”. The author wrote two short papers “Words of the Edition-in-Chief—Rocks are not microfacies”and “Words of the Edition-in-Chief—Rocks are not lithofacies”which were in Chinese and published in the Journal of Palaeogeography (Chinese Edition). However,they did not attract much attention of readers in China and outside China. In addition,in 1980s,some Chinese sedimentologists proposed “subfacies”and “microfacies”based on the macrofeatures of rocks from outcrops and drilling cores. The definition of this “microfacies”is totally different from the “microfacies”proposed by foreign sedimentologists in 1940s based on the microfeatures in thin-sections under microscope.
These problems appeared repeatedly and forced the author,as the Editor-in-Chief of the Journal of Palaeogeography(Chinese Edition and English Edition),to observe the policy of “A hundred flowers blossom and a hundred schools of thought contend ”,to write new papers “A review on the definitions of terms of sedimentary facies”both in Chinese and English,to clarify the definitions of the terms of sedimentary facies,i.e.,“facies”,“lithofacies”,two “microfacies”,“macrofacies”,“subfacies”,etc.,and to publish the new papers in the Journal of Palaeogeography(both Chinese Edition and English Edition). I hope that the new papers will attract attention of readers worldwide and they can write papers and participate in the discussion and contending of these problems,strive for getting some common understandings,and therefore promote the progress and development of sedimentology and palaeogeography.

Key words: sedimentary facies, facies, lithofacies, microfacies, macrofacies, subfacies, A hundred flowers blossom and a hundred schools of thought contend, definition
