The Standard Facies Belts
Published:January 01, 1992
Irrespective of geologic time and setting, shallow-water carbonates have a strong tendency to develop similar facies belts. These facies can be grouped into a platform model (Figure 2-1), best summarized by Wilson (1975). Important specifics on particular facies have been added from other authors.

Sedimentology and Sequence Stratigraphy of Reefs and Carbonate Platforms: A Short Course
Classical sequence stratigraphy has been developed primarily from siliciclastic systems. Application of the concept to carbonates has not been as straightforward as expected even though the basic tenets of sequence stratigraphy are supposed to be applicable to all depositional systems. Rather than force carbonate platforms into the straightjacket of a concept derived from another sediment family, this publication takes a different tack, starting out from the premise that sequence stratigraphy is a modern and sophisticated version of lithostratigraphy. It reviews sedimentologic principles governing the large-scale anatomy of reefs and platforms; looks at sequences and systems tracts from a sedimentologic point of view; assesses the differences between siliciclastics and carbonates in their response to sea level; evaluates processes that compete with sea level for control on carbonate sequences; and presents a set of guidelines for application of sequence stratigraphy to reefs and carbonate platforms.
