“…According to this hypothesis, the deposition of shallow water carbonate banks was restricted to horsts/paleo‐highs, while the grabens were filled with deep‐water sediments. (b) The second hypothesis, known as the “Megabank hypothesis” (Bryant et al., 1969; Meyerhoff & Hatten, 1968; Schlager & Ginsburg, 1981), suggests that during the Late Jurassic to the Mid‐Cretaceous, an extensive shallow‐water carbonate platform developed from the West Florida shelf to the Bahamas. Carbonate banks persisted in various forms throughout the Bahamas region during the Late Cretaceous and the beginning of the Cenozoic (Eberli & Ginsburg, 1987; Ladd & Sheridan, 1987; Sheridan et al., 1981).…”

The Eastern Cuban block has experienced a complex tectonic history characterized by plate interactions, resulting in a diverse array of geological features observable in the offshore sedimentary record. We investigate the tectonic evolution of offshore Eastern Cuba, specifically in the Old Bahamas Channel and its surrounding areas, by integrating multi‐channel seismic (MCS) reflection and published geological data. Our analysis employs stratigraphic frameworks and MCS data to assess deformation and key geological events in the region. We highlight the complex tectonic history of the Eastern Cuban block, marked by significant geodynamic events, such as rifting, the subduction of the oceanic Proto‐Caribbean plate, and syn‐orogenic and post‐orogenic phases. The seismic units observed in the majority of the study area reveal the early evolution of the Northern Proto‐Caribbean margin, subsequently impacted by the Cuban orogeny and the reactivation of the Cuban Transform Fault zone corresponding to a former plate boundary. We propose estimated ages for the seismic sequences, correlating them with available well data from neighboring regions. This study offers valuable insights into the tectonic history and geological evolution of offshore Eastern Cuba, contributing to a more comprehensive understanding of the region's geodynamic development.

“…On escarpments, erosion by gravity flows is thought to be restricted to the sediment veneer (Bryant et al, 1969;Freeman-Lynde, 1983;Paull, Freeman-Lynde, et al, 1990;Twichell et al, 1996). However, we do see a stark difference in the morphology of the escarpments-gentler slope gradient, convex slope profile-where the v-shaped canyons are located.…”
