“…Studying the youngest slope sedimentation captured by sea floor and subsurface data with the modern current pattern and the sea-level fluctuation from the last interglacial to the Recent can provide many new insights because the known processes can be related to their sedimentary products. An improved understanding of depositional variations of carbonate platform slopes is also important from an applied standpoint, because such deposits are potential hydrocarbon reservoirs, for example, in the Tengiz field of Kazakhstan and the Poza Rica field of Mexico, where large parts of the production come from ancient slope deposits (Enos, 1985;Janson et al, 2011;Collins et al, 2013).…”

Hydroacoustic and sedimentological data in the Santaren Channel covering both the leeward slope of Great Bahama Bank and the windward slope of Cay Sal Bank allow new insights into carbonate platform slope sedimentation. The data document the interplay between depositional and erosive processes on both slopes through time and provide information on the current regime and its influence on the slope sedimentary processes. This study emphasizes the diversity and complexity of the slope morphology and the sediment distribution of the youngest high‐frequency sequence, which has developed since the last glacial maximum. The processes triggering slope failures and the formation of channels and gullies differ on both slopes. At the leeward slope of the Great Bahama Bank, extensive slope failures occurred primarily during sea‐level lowering following an interglacial. These slope failures created a slope morphology that channelizes the exported platform sediments during the subsequent highstand. At the windward slope of Cay Sal Bank, contour currents and the local tectonic regime are responsible for slope failures. During sea‐level lowstands, downwelling induces turbidity currents. The interaction of turbidity and contour currents leads to the formation of a system of furrows and slope‐parallel sediment ridges. The discovered heterogeneities in slope sedimentation improve the understanding of carbonate slope sedimentation and provide implications for sequence stratigraphic interpretation of carbonate platform slopes.

The Valdorria carbonate platform, in northern Spain,features a well-preserved and continuous outcrop of a Bashkirian platform to basin transect. During the Asatauian (late Bashkirian), the platform growth changed gradually from a progradational to an aggradational mode, recording 10 most likely short-eccentricity-controlled cyclothems. The facies of the platform-top and slope have been mapped, and the architecture of each cyclothem schematically reconstructed. The distribution of microbial carbonates

“…Steep, microbial-boundstone-dominated slopes were common in Devonian to Middle Triassic carbonate platforms such as the Lennard Shelf (Playton & Kerans, 2015), Tengiz (Weber et al, 2003;Collins et al, 2014), Sierra del Cuera (Della Porta et al, 2003;Bahamonde et al, 2004;Kenter et al, 2005), the Permian platforms of West Texas and New Mexico (Bebout & Kerans, 1993;Tinker, 1998;Playton & Kerans, 2018), and the Sella and Latemar platforms of Italy (Blendinger, 1994;Keim & Schlager, 1999;Marangon et al, 2011). Platform slopes with similar boundstone development have also been reported from the Precambrian (e.g.…”

Carbonate platforms spanning intervals of global change provide an opportunity to identify causal links between the evolution of marine environment and depositional architecture. This study investigates the controls on platform geometry across the Palaeozoic to Mesozoic transition and yields new stratigraphic and palaeoenvironmental constraints on the Great Bank of Guizhou, a latest Permian to earliest Late Triassic isolated carbonate platform in the Nanpanjiang Basin of south China. Reconstruction of platform architecture was achieved by integrating field mapping, petrography, biostratigraphy, satellite imagery analysis and δ13C chemostratigraphy. In contrast to previous interpretations, this study indicates that: (i) the Great Bank of Guizhou transitioned during Early Triassic time from a low‐relief bank to a platform with high relief above the basin floor (up to 600 m) and steep slope angles (preserved up to 50°); and (ii) the oldest‐known platform‐margin reef of the Mesozoic Era grew along steep, prograding clinoforms in an outer‐margin to lower‐slope environment. Increasing platform relief during Early Triassic time was caused by limited sediment delivery to the basin margin and a high rate of accommodation creation driven by Indosinian convergence. The steep upper Olenekian (upper Lower Triassic) slope is dominated by well‐cemented grainstone, suggesting that high carbonate saturation states led to syndepositional or rapid post‐depositional sediment stabilization. Latest Spathian reef initiation coincided with global cooling following Early Triassic global warmth. The first Triassic framework‐building metazoans on the Great Bank of Guizhou were small calcareous sponges restricted to deeper water settings, but early Mesozoic reef builders were volumetrically dominated by Tubiphytes, a fossil genus of uncertain taxonomic affinity. In aggregate, the stratigraphic architecture of the Great Bank of Guizhou records sedimentary response to long‐term environmental and biological recovery from the end‐Permian mass extinction, highlighting the close connections among marine chemistry, marine ecosystems and carbonate depositional systems.
