[Significance]The study of the conceptual framework of the"Carbonate Factory"has been hailed by Reijmer as"one of the main advances in carbonate sedimentology achieved during the last three decades".It has a unique value in reconstructing deep time carbonate production processes and their controlling factors,as well as in predicting the impact of future climate and environmental changes on the sedimentary system.[Progress]The study of carbonate factories focuses on the major factors influencing the sedimentary system,including produc-ers,production processes and controls,and ecological accommodation.This is different from the traditional"facies model"that is based on lithofacies and sedimentary environment.As the related conceptual framework has matured,it is worth exploring new directions and research values of the carbonate factories to guide the innovation of theoretical and applied sedimentology.This study reviews the background of the formation of the conceptual framework of the carbonate factories,introduces their compositions and main influencing factors,and recommends the review and research papers in this special issue.[Prospects]The authors hope that through the introduction of these papers,domestic colleagues can be attracted to pay attention and interest to this field,and jointly promote the in-depth research and development of the carbonate factories.
