摘 要:近年来,《古地理学报》(中文版及英文版)连续收到一些来稿,其作者根据迈尔(Miall,1985)文章的观点和方法,把他们研究地区碎屑岩剖面中的每个岩层中的岩石挑出来,归纳出一些岩石类型,如砾岩、砂岩、细粒岩等,并称它们为岩相(lithofacies)。这不符合沉积相的定义。我曾写过几篇文章,即冯增昭(2018,2020)及Feng(2019),指出这些问题,希望国内外的作者、尤其是国内的作者,不再继续盲目地引用和传播迈尔(1985)文章的观点和方法。迈尔是第1个称岩石(实际上是沉积物)为岩相的人,他的观点和他提出的相分析方法误导了沉积相的正确定义及正常的相分析方法。本文主要讨论迈尔(Miall,1985)文章中的问题,即他把沉积物当作岩相并用岩相分析相。不讨论他文章的贡献及建筑单元中的一些术语欠严谨的问题。在这里,必须申明,本文中的相,是沉积岩石学中的相,不是火成岩岩石学、变质岩岩石学、古生物学、地层学、地球物理学、地球化学等地质学分支学科中的相。岩相、相和沉积相是同义的术语。当然,这些术语的定义是有争议的,希望遵循“百花齐放和百家争鸣”的方针和地质实践,逐步地解决这些争议。In recent years,the Journal of Palaeogeography(Chinese Edition and English Edition)continually received some manuscripts.The authors of these manuscripts,according to the viewpoint and method of Miall's paper(1985),selected rocks from each bed in the clastic sections of their study areas and induced some rock types,such as conglomerates,sandstones and fine-grained stones,and consid-ered them as lithofacies.It does not conform to the definition of lithofacies.I wrote some papers,i.e.,Feng(2018,2019,2020),to point out the problems and hope that the authors worldwide,especially Chi-nese authors,will not continually cite,spread and follow of viewpoint and method of Miall's paper(1985)blindly.Prof.Miall is the first person who considered rocks(in fact,the sediments)as lithofa-cies and proposed a facies analysis method.His viewpoint and facies analysis method confused the defini-tion of facies and facies analysis method.My current paper is a special article to discuss the principal prob-lems of Miall's paper(1985),i.e.,he considered the sediments as lithofacies and utilized lithofacies to analyze facies,but not to discuss the contributions and less strictness of architectural elements of his pa-per.Here,I have to declare that the facies in my current paper is the facies of sedimentary petrology,but not of other geological disciplines,such as igneous petrology,metamorphic petrology,palaeontology,stratigraphy,geophysics,geochemistry.Certainly,the definitions of facies and lithofacies are controver-sial.I will adhere to the policy of“A hundred flowers blossom and a hundred schools of thought contend”and hope that through academic discussions,contends and geological practice,these problems will be solved gradually.
