A new PDF document, "Principles of Carbonate Sedimentology: Origins, Processes, and Modern Analogues" (2025 edition), is now available for download at the end of this article. This PDF integrates classical petrography with recent advances in geomicrobiology and isotope geochemistry.

High rates of seafloor spreading lead to extensive hydrothermal venting. This process strips magnesium from seawater, resulting in a low marine molar ratio (

Old View: "Why is there no modern dolomite forming?" New View (Liu et al., Earth-Science Reviews , 2024): is possible with high Si/Al ratios and low sulfate concentrations. The "Vasconcelos Model" (2000s) has been updated to include organo-mineral interactions —specifically, the carboxylic groups in fungal cell walls accelerate Mg-Ca ordering.

Unlike siliciclastic rocks derived from the mechanical weathering of pre-existing landmasses, carbonate rocks are predominantly intrabasinal and biological in origin. They are composed chiefly of calcium carbonate ( CaCO3cap C a cap C cap O sub 3
