“…The external zone comprises a heterogeneous suite of Mesozoic and Early Cenozoic passive continental margin deposits (Garcia-Hernandez et al 1980;Everts 1991). Those Triassic to Early Miocene sediments are detached from the Palaeozoic basement and have been thrust northward onto the southern margin of the Iberian Craton (Blankenship 1992).…”

“…In the southwesternmost part of the Prebetic domain, various isolated mountain ranges expose Palaeogene rocks, reflecting the transition from the inner shelf to the hemipelagic outer shelf (Carche, Benis, Enmedio; see Kenter et al 1990). Outcrops along the deeper and more hemipelagic shelf are frequent in the areas of Relleu, Penaguila, Torremanzanas, and Benifallim (e.g., Everts 1991;Geel 2000) as well as the Agost section, representing the Internal Prebetics (e.g. Molina et al 2000;Ortiz et al 2008;Monechi & Tori 2010).…”

“…Furthermore, frequently transported larger benthic foraminifera from the inner platform (e.g., nummulitids and alveolinids) and autochthonous forms of orthophragminids are recorded. Zoophycus traces indicate a palaeo water depth of ~300 m that refers to the lower slope (Seilacher 1967;Everts 1991). The succession of Relleu encompasses 3 depositional sequences during the Eocene and 5 depositional sequences during the Oligocene (Geel 2000).…”

Depositional geometries as imaged in seismic lines, logging data, and quantitative petrographic data were used to analyse the slope and toe of slope deposits of the Miocene distally steepened carbonate ramp of Great Bahama Bank. The shedding pattern along the slope of this ramp is more complex than it is along the slope of the Pliocene±Pleistocene flattopped carbonate platform. Compositional changes and compositional trends of periplatform sediments correlate with the positions of geophysically-defined sequence boundaries. Two types of depositional sequences occur. The first sequence is characterised by laterally traceable sequence-internal reflections, whereas the second type contains major intrasequential incisions. Erosional incisions and sedimentary infills of these canyons by turbidites formed during sea-level lowstands, as is indicated by the composition of the turbidites having a mixture of shallow-water and pelagic particles. Highstand turbidites are characterised by more extensive, laterally traceable geometries and by the occurrence of abundant shallow-water particles. In contrast to highstand turbidites shed from the Pliocene±Pleistocene flat-topped platform, shallow-water components in highstand turbidites of the Miocene ramp are of skeletal origin. The stacking pattern of the periplatform deposits is controlled by sealevel fluctuations. Four orders of sea-level changes are distinguished. Third-order cycles are delimited by sequence boundaries, and fourth (100,000 a) order cycles govern the bundling of turbidites into packages. Fifth (40,000 a) and sixth (23,000 a) order cycles are recorded in the background sediments and resolvable with spectral analysis.

“…Recorded within the composition of the calciturbidites were changes related to either facies alterations or to variations in sea level (Haak and Schlager 1989;Everts 1991;Reijmer et al 1992;Herbig and Bender 1992). For example, in the Vercors (SE France) small and large-scale cycles in clinoform composition were observed Everts and Reijmer 1995).…”

In this paper data are presented on the composition of sediments deposited at the toe of slope during progradation or retreat of Triassic carbonate platforms in the Dolomites (Italy). For this purpose a succession was studied from the toe of slope of a Triassic (Carnian) carbonate platform (Picco di Vallendro/Dürrenstein, Dolomites, Italy). The microfacies analysis of selected calciturbidites sequences revealed a reduced input of oncolites and ooids during progradation and an increase in clasts. The main input, however, was derived from the reefs on the platform. Retrogradation of the platform showed an increase of filaments and radiolarians (open ocean biota) as well as carbonate mud and a reduced input of grains that originated within the reefs on the platform. Both during progradation and retrogradation parts of the platform were flooded and could produce excess sediment that could be exported to the surrounding basins. However, the absence of platform interior biota documents that progradation occurred from sediments of the reefal belt, probably during relative sea-level lowstands. Carbonate composition varies systematically with toe-of-slope progradation/retrogradation and, thus, argues for carbonate production as the main driver of the geometries observed at the toe of slope.
