extracting calcium and bicarbonate from seawater to build skeletons or shells.
Pressure: High pressure increases solubility. Carbonates tend to dissolve in deep, high-pressure abyssal environments (below the Carbonate Compensation Depth - CCD).
CO₂ Content:
- Microbial mats, cyanobacteria, EPS: Mediate carbonate nucleation, bind sediments, form stromatolites and thrombolites.
- Mechanism: Photosynthesis raises pH locally, inducing carbonate precipitation.
5.3 Burial Diagenesis
The "extra quality" or purity of a carbonate deposit depends on three environmental "sweet spots": Warm Water: origin of carbonate sedimentary rocks pdf extra quality
Reefal Framework: In situ bioherms (reefs) create a rigid framework that resists wave action. These act as barriers, creating protected lagoons behind them.
Slope and Deep Basin: Deeper water sediments composed of fine-grained periplatform ooze and turbidites (debris flows shed from the platform margin). Deep marine carbonates (chalk) are composed largely of calcareous nannoplankton (e.g., coccolithophores).
