37. SEISMIC STRATIGRAPHY AND GEOLOGIC DEVELOPMENT OF AN OPEN-OCEAN CARBONATE SLOPE: THE NORTHERN MARGIN OF LITTLE BAHAMA BANK1'2
Carbonate slope development north of Little Bahama Bank (LBB) has been investigated via a seismic stratigraphic analysis of approximately 1350 km of air-gun seismic reflection profiles. Slope development is shown to be complex be-cause of the interaction of slope accretion, sediment bypassing, and s...

Carbonate slope development north of Little Bahama Bank (LBB) has been investigated via a seismic stratigraphic analysis of approximately 1350 km of air-gun seismic reflection profiles. Slope development is shown to be complex be-cause of the interaction of slope accretion, sediment bypassing, and submarine erosion to produce a single open-ocean carbonate slope. The present slope north of LBB did not develop until after the complete drowning of the southern Blake Plateau near the end of the Cretaceous. Beginning in the early Tertiary and continuing through the present, this slope has accreted laterally by the accumulation of periplatform oozes along its upper slope, whereas submarine slides and sediment gravity flows have bypassed the upper slope, resulting in a lower slope apron of slide blocks, turbidites, and debris flows.
