The Basic Nature of Carbonate Sediments and Sedimentation
The cool-water carbonate factory refers to carbonate sediment formation in the cooler waters north or south of 30° latitude, vertically within the cooler waters of the thermocline, or in areas of upwelling of cold nutrient-rich waters (Schlager, 2005). Sediment producers are predominantly heterotrophs, sediment is generally skeletal hash with ...
The evolution of the marine carbonate factory
Downloadable (with restrictions)! Calcium carbonate formation is the primary pathway by which carbon is returned from the ocean–atmosphere system to the solid Earth1,2. 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 cycling1,2.
Applications
Additionally, in the oil industry, the need of calcium carbonate is highly desirable which is been used as a formation-bridging and filtercake-sealing agent added to drilling fluids. As result, it increases the density of the drilling fluids in order to control the downhole pressure.
