The two dominant minerals are (CaCO₃) and dolomite (CaMg(CO₃)₂). A rock composed primarily of calcite is a limestone , while a rock where the calcite has been mostly replaced by dolomite is a dolostone (or dolomite rock). It is important to note that carbonate sediments are not merely detrital fragments transported from elsewhere; they are "born" within the depositional environment. They form either through direct chemical precipitation from seawater or as the calcitic or aragonitic skeletons of countless marine organisms.

Flat-topped platforms bounded by an abrupt outer edge, typically armored by continuous barrier reefs or ooid shoals that restrict wave energy, creating quiet lagoons behind them.
The precipitation of carbonate is controlled by the reaction:
Carbonate accumulation requires the saturation of calcium and carbonate ions in the water column. This precipitation occurs through three fundamental pathways. 1. Biogenic Secretion (Controlled Mineralisation) Open-access alternatives: Search ; some older volumes are

No modern primary dolomite forms in normal seawater at ambient temperatures. Yet ancient dolostones are massive.

True "extra quality" often comes from library-licensed eBooks (e.g., Springer, Elsevier) or open-access articles from The Depositional Record (IAS journal).

The origin of carbonate rocks is intricately linked to the inorganic carbon cycle, where carbon is exchanged between the atmosphere, hydrosphere, and geosphere.
