In recent years,the Journal of Palaeogeography(Chinese Edition and English Edition)continually received manuscripts,in which some authors are from China and some are from Pakistan,Lithuania,Morocco,South Africa,etc.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 considered 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 Chinese authors,will not continually cite,spread and follow Miall's paper(1985)viewpoint and method blindly.Prof.Miall is the first person who considered rocks(in fact,the sediments)as lithofacies and proposed a facies analysis method.His viewpoint and facies analysis method confused the definition of facies and facies analysis method.My current paper is a special article to discuss the principal problems 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 paper.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 controversial.My current paper will adhere to the policy of"A hundred flowers blossom and a hundred schools of thought contend".I hope that through aca-demic discussions,contends and geological practice,these problems will be solved gradually.
