The shallow shelf interior environment ([[:file:carbonate-reservoir-models-facies-diagenesis-and-flow-characterization_fig2.png|Figure 2]]) is dominated by low-energy waters that allow lime mud to accumulate. [[Storm deposits and currents|Storms]], however, churn the sediment into [[suspension]], winnowing out the fine-sized material and concentrating the coarse material. Near shorelines, the shelf environment may be composed of offshore [[bar]]s and [[spit]]s oriented parallel to shoreline. Shorelines that face heavy wave action accumulate [[carbonate sand]] or gravel. [[Tidal current]]s are concentrated in channels between islands and produce [[tidal delta]]s on the lee side of the island.

The shelf margin complex ([[:file:carbonate-reservoir-models-facies-diagenesis-and-flow-characterization_fig2.png|Figure 2]]) is characterized by the presence of [[carbonate sands]] and [[reefs]]. [[Reef]]s are commonly found at the shelf edge where their rigid framework can withstand strong wave action and they can take advantage of the nutrients upwelling from the deeper waters. [[Carbonate sand]]s derived from a reef or from plants and animals inhabiting the shelf edge accumulate along a wide belt that follows the break between the shelf edge and the slope. [[Tidal current|Tidal]] and [[Storm deposits and currents|storm currents]] mold the sand belt into tidal channels and bars.

The slope ([[:file:carbonate-reservoir-models-facies-diagenesis-and-flow-characterization_fig2.png|Figure 2]]) is dominated by sediment transport seaward from the shelf margin. Fine-grained sediment settles to the bottom forming thin-bedded [[mudstone]]s, while slumps, [[debris flow]]s, and [[turbidity current]]s form coarse-grained bodies of [[breccia]], [[conglomerate]], and [[carbonate sand]]. The resulting [[facies pattern]]s depend upon the relief of the shelf margin and the nature of the shallow water portion of the margin.<ref name=pt06r87>Mcllreath, I. A., James, N.
