“…Also, an extensive progradation imaged on the seismic lines of the western margin of the GBB has advanced the bank edge up to 27 km basinward over the original, nowburied, fault-induced topography ( Fig. 2; Eberli and Ginsburg, 1989). Time-equivalent sediments drilled in the industrial well, Great Isaac, on northwestern GBB , corroborated the facies successions proposed to explain the interpreted progradational sequence.…”

“…These profiles (Fig. 2) show that the modern pattern of banks and channels is not solely a reflection of the topography formed during the Jurassic or mid-Cretaceous, but rather the combined result of several cycles of destructive and prograding processes Ginsburg, 1987, 1989). The profiles indicate that tectonism controlled the initial pattern of the platforms, whereas progradation subsequently infilled some of the seaways.…”

“…Seismic stratigraphy reveals multiple repetitions of the dual process of tectonic segmentation and depositional coalescence, which continuously modifies the platform pattern Ginsburg, 1987, 1989). The productive bank tops provide material that both smooths the tectonic relief with the infilling of intraplatform seaways and promotes bank-margin progradation (Figs.…”

“…The Great Bahama Bank is a pure carbonate environment in a subtropical, low-latitude setting and, as such, is an ideal place to evaluate the sedimentary record and timing of global sea-level changes. Its western margin comprises numerous Miocene to Holocene, laterally stacked, prograding sequences, as revealed in seismic stratigraphic studies, making it an especially suitable location for a high-resolution study of Neogene to Quaternary sea-level changes Ginsburg, 1987, 1989). Onlapping patterns can be used to separate sequences within the prograding package and to reconstruct the local sea-level history.…”

“…Onlapping patterns can be used to separate sequences within the prograding package and to reconstruct the local sea-level history. Comparison with the global cycle chart of Haq et al (1987) led to the interpretation that each pulse of progradation is the record of one sea-level fall and rise (Eberli and Ginsburg, 1989).…”

Multiple, spatially restricted, partly enclosed karst sub-basins with as much as 100 m of relief occur on a mid-carbonate platform setting beneath the modern estuaries of Tampa Bay and Charlotte Harbor located along the west-central Florida coastline. A relatively high-amplitude seismic basement consists of the mostly carbonate, upper Oligocene to middle Miocene Arcadia Formation, which has been signifi cantly deformed into folds, sags, warps and sinkholes. Presumably, this deformation was caused during a mid-to-late Miocene sea-level lowstand by deep-seated dissolution of carbonates, evaporites or both, resulting in collapse of the overlying stratigraphy, thus creating palaeotopographic depressions.Seismic sequences containing prograding clinoforms fi lled approximately 90% of the accommodation space of these western Florida sub-basins. Borehole data indicate that sediment fi ll is mostly siliciclastic deposited within deltaic depositional systems. The sedimentary fi ll in the Tampa Bay and Charlotte Harbor sub-basins is mostly assigned to the upper Peace River Formation of late Miocene to early Pliocene age. This fi ll is part of a >1000 km long, Tertiary siliciclastic deposit that stretches north-to-south down peninsular Florida. Sediment fi ll of these two sub-basins is linked to erosion and remobilization of pre-existing, middle Miocene quartz-rich sediments via enhanced sediment transport by local, short-length rivers and discharge into coastalmarine depositional environments. Increased sediment discharge possibly resulted from amplifi ed thunderstorm activity and enhanced runoff during a warm period of the Pliocene.Rather than incised valley fi lls or reef-margin, backfi lled basins, Tampa Bay and Charlotte Harbor represent spatially restricted, sediment-fi lled karst palaeotopographic lows. The 'dimpling' of a carbonate platform by karst sub-basins provides a previously unrecognized mechanism for the creation of accommodation that can result in the 'drowning' of a carbonate platform by siliciclastics.
