Operates in heterozoan-dominated regimes (e.g., bryozoans, mollusks, foraminifera) where temperatures fall below 20°C. Production rates are lower, and light is not a limiting factor.

: Inorganic processes also play a role, particularly in forming ooids (spherical grains) or lime mud when seawater becomes supersaturated with calcium and bicarbonate ions. origin of carbonate sedimentary rocks pdf new
Components are bound together during deposition by encrusting organisms (e.g., reef frameworks). Diagenetic Environments and Textural Consequences
Carbonate accumulation occurs in specific geographic settings that are heavily insulated from muddy or sandy continental runoff. High inputs of siliciclastic sediment choke carbonate-producing organisms and muddy the clear water they require to photosynthesize. Carbonate depositional systems are generally categorized into distinct architectural models: Operates in heterozoan-dominated regimes (e
exsolution. This effect restricts prominent primary carbonate accumulation to shallow-water environments above the Carbonate Compensation Depth (CCD).
One of the most persistent questions in geology is the (CaMg(CO₃)₂). Modern seas precipitate mostly aragonite and calcite, yet ancient rock records are filled with dolomite. The "James & Jones" textbook explores modern models of dolomitization, including seepage-reflux, mixing-zone, and microbial mediation models. Operates in heterozoan-dominated regimes (e.g.
Diagenesis refers to the physical and chemical changes sediments undergo after deposition. It is critical for origin studies because it changes the original texture.
