The evolution of the marine carbonate factory Semantic Scholar
Calcium carbonate formation is the primary pathway by which carbon is returned from the ocean–atmosphere system to the solid Earth^ 1,2 . The removal of dissolved inorganic carbon from seawater by precipitation of carbonate minerals—the marine carbonate factory—plays a critical role in shaping marine biogeochemical According to this relationship, six basic geometric patterns of the carbonate platforms were summarized, namely progradation with aggradation, aggradation, back-stepping, "empty bucket," drowningSedimentology and sequence stratigraphy of carbonate rocks

The "Carbonate Factory" Revisited: A Reexamination of Sediment
There are two widely used models of sediment production on carbonate shelves: (1) production varying with depth, and (2) production as a function of depth and distance from the platform margin. Here we recalculate carbonate production on Great Bahama Bank west and northwest of Andros Island using Broecker and Takahashi's (1966) pioneering Noel James, Professor of Geology at Queen’s University, Canada, has, for over 40 years focused his research on carbonate sediments and rocks that range from the modern seafloor to the Archean, studying their origin via extensive marine and terrestrial fieldwork, petrography, and geochemistry.

A subseafloor carbonate factory across the Triassic-Jurassic
Abstract. Triassic-Jurassic (T-J) boundary successions record a paucity of carbonate in association with the mass extinction.

Stratigraphic evolution and carbonate factory implications: Case study
By observing modern carbonate systems, at a carbonate platform scale, Schlager (2000; 2003; 2005) defined and individualized three different marine precipitation modes based on stratigraphic and diagenetic principles, that is T/tropical, C/cool water and M/microbial or mud-mound factories, each factory with its own characteristics regarding Then, spatial analysis is used to calibrate different carbonate factory functions that predict oceanic zones favorable to specific carbonate factories.

Carbonate factory turnovers influenced by the monsoon (Xisha
Carbonate factory turnovers are the integrated result of climatic, oceanographic and biological controls. Sedimentological, geochemical and palaeontological data from core XK-1 drilled in the Xisha Islands, South China Sea, reveal that photozoan to heterozoan carbonate factory turnovers during the Early and Middle Miocene in isolated Because organic carbon contains a larger fraction of the light isotope 12 C than inorganic carbonate, variations in the carbon isotopic record of sedimentary rocks are thought to represent changes in the Authigenic Carbonate and the History of the Global
