Depositional environments and sequence stratigraphy of a mixed siliciclastic-carbonate ramp: An example from the cenomanian to Turonian Galala Formation in the northern Eastern Desert, Egypt

Journal of African Earth Sciences, 2018
Sedimentologic, stratigraphic and ichnological data are integrated to develop a model linking base-level changes to depositional evolution of a mixed siliciclastic-carbonate ramp.

Carbonate ramps, 1973–1996: a historical review

Geological Society, London, Special Publications, 1998
Abstract The carbonate ramp as a type of sedimentary depositional platform was conceived after failed attempts to fit some carbonate facies patterns to shelf models. Ramps were first defined as two-dimensional (2D) depositional surfaces along which facies variations reflect differences in the oceanographic environment from shore to basin ...

Oil distribution in outcropping carbonate-ramp reservoirs (Maiella Mountain, Central Italy): Three-dimensional models constrained by dense historical well data and laboratory measurements

American Association of Petroleum Geologists Bulletin, 2018
Heavy oil and bitumens have been exploited in Italy during the past, in particular over the Maiella Mountain’s northwest flank (Central Italy), where relatively undeformed, hydrocarbon-bearing carbonate-ramp reservoirs of the Bolognano Formation crop out.

Carbonate Ramp--Alternative to Shelf Model: ABSTRACT

AAPG Bulletin, 1973
One of the most common depositional models for carbonate rocks is the "shallow shelf." This model typically is constructed to show a nearly flat platform and a clearly defined shelf-slope break. Typically, there are detrital carbonates on the platforms, reefs or banks at the shelf-margin and basinal rocks seaward of the reefs. The usual analogs are the

Short Paper: A standardized model for Tethyan Tertiary carbonate ramps

Journal of the Geological Society, 1989
Low latitude carbonates in massive and clinoform bedded sheets, termed ramps, occur throughout the Tertiary Tethyan realm, and are characterized by recurring biofacies usually including large foraminifera, rhodolithic algae, coralgal patch-reef and gastropod dominated sequences.

Mud buildups on a Middle Devonian carbonate ramp (Algerian Sahara)

Geological Society, London, Special Publications, 1998
Abstract During sea-level highstand in late Mid-Devonian time, a carbonate ramp was established on the vast shelf of the Northwest African Craton, in the Ahnet and Mouydir Basins of southern Algeria. The ramp was at least 400 km wide and 700 km long and sloped, in front of a local shoal of rugose-tabulate-stromatoporoid dominated biostromes ...

Development of transient carbonate ramps in an evolving foreland basin

Basin Research, 2018
AbstractThis study of Eocene carbonate succession in the Dinaric Foreland Basin of northern Dalmatia, Croatia, integrates palaeontological and sedimentological data to document a range of carbonate ramps formed intermittently during the basin tectonic development. The end‐Cretaceous basal erosional unconformity records the coupling of Adria and Eurasia

Cretaceous Tide-Dominated Carbonate Ramp: Comparison of Reservoir Heterogeneity in Tide- Versus Wave-Dominated Carbonate Ramp Systems: ABSTRACT

AAPG Bulletin, 1995
Cretaceous (upper Albian) carbonate ramp strata, Pecos River Canyon, Texas, provide a uniquely continuous exposure of a tide-dominated ramp reservoir analog. The continuous 100-km shelf-to-basin outcrop begins in inner ramp mud-rich facies that record both high-frequency (20-100 ky) and intermediate frequency (>200 ky) cyclicity.

The Modern Carbonate Ramp Slope of Central West Florida

SEPM Journal of Sedimentary Research, 1988
ABSTRACT A holistic investigation of the modern carbonate ramp slope of central west Florida has been completed via analysis of approximately 1,500 km of air-gun seismic reflection profiles tied to two drillcores and bottom samples recovered at 92 stations. Our primary goal has been to characterize modern depositional processes and products; to compare

Fracture distribution along an Upper Jurassic carbonate ramp, NE Spain

Marine and Petroleum Geology, 2016
Understanding the distribution of natural fractures in sedimentary systems is of high relevance for the exploration and production of fluids in the subsurface. This study focuses on a Kimmeridgian mixed siliciclastic-carbonate ramp system, which is part of the Jurassic limestones outcropping in the northeastern Iberian Chain.
