Figure 6. Schematic diagram of facies within a prograding sequence along the Great Bahama Bank. Five major depositional environments are recognized: (1) the platform top, composed of shallow-water carbonates separated by exposure horizons; (2) the upper slope, with thick bulges of fine-grained platform-derived material and channel incisions; (3) the middle to lower slope, with variable facies assemblages of peri-platform material, pelagic ooze, and redeposited carbonates with channels and lobes; (4) the toe-of-slope, the main depocenter for redeposited carbonate that accumulates in mounded lobes within marl/limestone alternations as background sediment; and (5) the distal portion of the sequences, dominated by cyclic marl/limestone alternations with few turbidites. SB = sequence boundary, HST = highstand systems tract, LST = lowstand systems tract.
