There are five basic carbonate depositional environments. From shore to basin, they are ''[[peritidal]]'' (tidal flat), ''[[shallow shelf interior]], [[shelf margin complex]], [[slope]]'', and ''[[basin]]'' ([[:file:carbonate-reservoir-models-facies-diagenesis-and-flow-characterization_fig2.png|Figure 2]]).

Moore, eds., 1983, [http://store.aapg.org/detail.aspx?id=656 Carbonate depositional environments]: AAPG Memoir 33, 708 p.</ref>)

The peritidal depositional environment is complex ([[:file:carbonate-reservoir-models-facies-diagenesis-and-flow-characterization_fig2.png|Figure 2]]). Sediments deposited between mean high and mean low tide are called ''[[intertidal]] sediments'', sediments deposited above mean high tide are called ''[[supratidal]] sediments'', and sediments deposited below mean low tide are called ''[[subtidal]] sediments''. In arid and semi-arid climates, evaporite flats ([[sabkha]]s) are present from which [[gypsum]] and [[halite]] are deposited. [[Sand dune|Eolian sand dunes]] composed of siliciclastic or carbonate grains may form on the supratidal surface.
