The "carbonate factory" requires specific conditions: clear, warm, shallow water with normal salinity and minimal sediment input from land. Carbonates & Other Rocks
Direct chemical precipitation occurs without direct biological intervention when seawater becomes highly supersaturated. This typically happens due to temperature increases, intense evaporation, or rapid degassing of CO2CO sub 2 origin of carbonate sedimentary rocks pdf extra quality
The sedimentation of carbonate minerals can occur in a variety of environments, including marine, freshwater, and terrestrial environments. The diagenesis of carbonate sediments involves the cementation of carbonate minerals, which can occur through a variety of mechanisms, including compaction, cementation, and replacement.

Focuses on the relative proportions of allochems and the nature of the binding material:
Inorganically precipitated carbonate occurs when seawater or lake water becomes supersaturated with respect to calcium carbonate. This often happens due to a rise in water temperature, a decrease in pressure, or evaporation, causing CaCO3cap C a cap C cap O sub 3
