Controls on Carbonate Platforms and Basin Development
Controls on Carbonate Platform and Basin Development - This volume is derived from the SEPM Research Symposium of the same name that was formulated for the Los Angeles meetings of AAPG and SEPM in 1987. The volume covers many subjects relative to geology of carbonate platforms and adjoining slopes and basins. A preliminary section, based on principles of deposition and computer modeling studies, is followed by a group of papers devoted to examples of carbonate platforms on passive cratonal margins resulting from rifting. Some of the examples are from major platform systems around North America and the Mesozoic of Tethys. Other studies are of local and individual platform-basin systems. Examples of both ramps and rimmed platforms are included. The case histories presented span the whole of geologic time from early in the Proterozoic to the Holocene.

Late Jurassic (Kimmeridgian) to Early Cretaceous (Valanginian) carbonate platforms exhibit "keep-up" and "give-up" types of growth in the Western Atlantic. Twenty seismic lines and four well ties delineate the shelf-edge geometries, depositional systems, and chronostratigraphy. Geometric relations together with paleontologic and lithologic facies data permit interpretation of the primary controlling factors on platform evolution.
Atlantic platform "keep-up" growth and development during successive tectono-eustatic fluctuations occur in two stages and vary directly with the supply of siliciclastics. Platform growth stages receiving siliciclastics prograde; those which do not aggrade. During stage I (Kimmeridgian), 8.1 km (5 mi) of margin progradation occurred...
