Abstract

The open-ocean carbonate slope north of Little Bahama Bank consists of a relatively steep (4o) upper slope between water depths of 200 and 900m, and a more gentle (1-2o) lower slope between depths of 900 and 1300+ m. The upper slope is dissected by numerous, small, submarine canyons (50-150m in relief) that act as a line source for the downslope transport of coarse-grained debris. The lower slope is devoid of any well-defined canyons but does contain numerous, small (1-5m) hummocks of uncertain origin and numerous, larger (5-40m), patchily distributed, ahermatypic coral mounds. Seismic facies interpretations for both of these slope domains are presented. Both the geomorphology and sedimentary facies relationships of the carbonate apron north of Little Bahama Bank differ significantly from the classic submarine fan model. As such, a carbonate apron model offers an alternative to the fan model for palaeoenvironmental analysis of ancient, open-ocean carbonate slope sequences.-from Authors
