Carbonate sedimentary rocks compose approximately one-fifth of the stratigraphic record. They serve as primary archives of Earth's ocean chemistry, host vast groundwater aquifers, and contain major global hydrocarbon and mineral reserves. Understanding the origin of these rocks requires examining biological, chemical, and physical processes across geological time. 1. Fundamental Chemistry of Carbonate Systems Understanding the origin of these rocks requires examining

The Folk classification emphasizes the composition of the rock, dividing it into three main components: allochems (grains), microcrystalline calcite ooze (micrite matrix), and sparry calcite cement. Terms like "biomicrite" (fossils in a micrite matrix) or "oosparite" (ooids in sparry calcite cement) are created. This system provides exquisite detail on the rock's constituents and history. Terms like "biomicrite" (fossils in a micrite matrix)

Diagenesis encompasses all physical, chemical, and biological changes that alter carbonate sediments after deposition, excluding high-temperature metamorphism. Carbonates are highly susceptible to diagenesis due to the instability of aragonite and high-Mg calcite. Diagenetic Environments and Processes Diagenetic Realm Predominant Processes Fabric Changes
