Abstract: The proposal of carbonate factory and its classification study are of great significance for promoting the development of carbonate sedimentology. However, the current classification scheme is not sufficient to cover all carbonate sediments, so it is urgent to clarify different carbonate factories at the level of mechanism and process. The carbon utilized by traditional carbonate factories mainly comes from the atmospheric and oceanic inorganic carbon pools, while some special marine and continental carbonate factories mainly fix carbons from exogenous carbon pools, so the two are fundamentally different. The latter is often of great significance for tracing deep water environment and climate events. Taking hydrocarbon seep carbonate as an example, this paper puts forward the concept of “Cold-seep Carbonate Factory” formally. In addition, its sedimentary characteristics, biological composition and biogeochemical processes have been summarized, and its geological significance has been addressed with an example. The type of carbonate factory based on exogenous carbon pool deserves much attention.
