By Larry J. Doyle

Through the years, the sector of sedimentology has turn into subdivided into a number of specialities. of the most important teams are those that research clastic rocks and those that learn carbonates. there's little conversation among the 2: journals seem that are solely dedicated to one or the opposite, and study meetings are typically collectively particular. however, rocks themselves can't be "pigeon-holed" during this method - the facies switch from clastic to carbonate either laterally and during time. This quantity stems from the editors' observations of such alterations within the Gulf of Mexico and their cognizance that those geologically vital transitions have been being mostly missed due to expert compartmentilization. The booklet opens with a bankruptcy which supplies an outline of the full photo of world styles of carbonate and clastic sedimentation. It then proceeds to a dialogue of sedimentary versions of siliciclastic deposits and coral reef relationships. the remainder of the ebook contains 8 case reports on carbonate-clastic transitions, and a last bankruptcy on regulate of carbonate-clastic sedimentation platforms through baroclinic coastal currents.

2 ) exhibits practically no reef. This is the last lobe system that occurred during the so-called Messinian Salinity Crisis Event. In Unit 2 (Fig. 2 ) . the configuration of reefs (smaller. isolated reefs as well as the scalloped arcs), reflects the configuration of the frontal profile of the fan-delta lobes. The dimensions of the reefs are similar to the perimeter of the lobes crest, while the depressions between them have been accurately fossilized by the reef-talus deposits. 3 REEFS ASSOCIATED WITH DELTAIC FACIES We have found two different situations in which reefs are associated with different kinds of deposits originating in the deltaic environment.
