The shelf-to-basin transition defines the geometry of carbonate bodies. On protected inner shelves, lagoons collect fine-grained mud and peloids. On the high-energy shelf margin, reefs and ooid shoals form massive, porous structures. Beyond the margin, the carbonate slope and deep basin receive "pelagic rain," consisting of the shells of planktonic organisms like foraminifera and coccolithophores.

Carbonate sedimentation is broadly classified into distinct ecological and chemical regimes, known as carbonate factories. SEPM Carbonate Research Group

Grainstones/packstones at rim; wackestones/mudstones in lagoon. Great Barrier Reef; Belize Shelf.

Steep slope; protected quiet lagoon behind a continuous outer reef or ooid shoal barrier.

To properly analyze their origin, geologists rely on two foundational classification schemes:
