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 cycling 1,2.A paucity of …

Triassic-Jurassic (T-J) boundary successions record a paucity of carbonate in association with the mass extinction. Here we demonstrate that three globally disparate T-J sections contain volumetrically important early diagenetic carbonate, i.e., carbonate formed soon after deposition of the sediment but commonly ignored as secondary, that contains …

A large input of siliciclastic sediments commonly suppressed production of carbonates and deteriorated the carbonate factory. In the earliest Ordovician, however, ...

The carbonate factories model, as defined at the beginning of the century, provides a subdivision of marine carbonate sediment production-systems based on the style of carbonate precipitation. The main factors controlling marine carbonate precipitation are light, water temperature, nutrients, salinity, substrate and carbonate …

The carbonate factory is spatially and temporally highly variable and is not simply a uniform production line. This fact, coupled with the likely importance of selective early dissolution, may in part explain why accumulation rates estimated from ancient strata are lower than the production rates measured over short time periods.

The aim of this study is to synthesize current knowledge on the Aptian giant lacustrine carbonate factory of the central South Atlantic, and propose that it reflects the direct influence of mantle-related CO 2 on basement geology and volcanic catchments, resulting in a vast chemogenic carbonate factory, which seems to have had more in …

Thus, in this example, palaeodune sediment faithfully records the nature of the adjacent inner neritic carbonate factory. By inference, aeolianites are potential repositories of information about the nature of long-vanished marine systems that have been removed due to erosion, tectonic obliteration or are inaccessible in the subsurface.

A carbonate factory is a carbonate precipitation mode defined by an ecosystem (cf. James and Jones, 2015; Michel et al., 2019). ... The authors also extend their thanks to Dr. Karin Goldberg from the Department of Geology, Kansas State University, whose thoughtful and detailed corrections beyond the accurate suggestions …

This approach aims to analyze the specific controls of carbonate production. The study of carbonate production processes represents a new trend in the future development of carbonate sedimentology, and it is expected to make significant contributions to sedimentary geology, paleoenvironmental studies, and reservoir geology.

This study thus provides new insights into the variability of shallow water carbonate deposition in monsoon-influenced areas and also shows that carbonate factory turnovers can contribute to a better understanding of the monsoon's evolution.

These carbonate rocks from reefs are used by sedimentologist to help construct the past geological events. Reef carbonates contain a good amount of hydrocarbons. Carbonates can form in many different types of depositional settings including basin and slope, reefs, and carbonate platforms.

The resulting neritic lime-mud component of the shallow-water carbonate factory became predominant during the Jurassic, paralleling the increase in atmospheric p CO 2, while the decreasing importance of the benthic automicrite factory parallels the diversification of calcifying metazoans, phytoplankton and zooplankton.
