Origin Of Carbonate Sedimentary Rocks Pdf Extra Quality

These are the "factory" for most carbonates, where high light penetration allows for immense organic growth (corals, algae).

Purely physical and chemical conditions can trigger the direct precipitate of carbonate minerals without direct biological intervention. These are spherical, sand-sized grains ( origin of carbonate sedimentary rocks pdf extra quality

Precipitation of calcite occurs when: $$[Ca^2+][CO_3^2-] > K_sp$$ These are the "factory" for most carbonates, where

Equant calcite cementation, neomorphism of aragonite to calcite. Destroys primary porosity; stabilizes mineralogy. Mechanical and chemical compaction, stylolitization. Reduces volume; creates pressure-solution seams. Dolomitization K_sp$$ Equant calcite cementation

: Emphasizes the nature of allochemical constituents (grains) and the matrix (micrite vs. sparite). Folk introduced terms like “biomicrite” (fossils in lime mud) and “oosparite” (ooids in sparry calcite cement).

Occurs at or just below the seafloor in contact with open seawater. Key processes include:
