Figure 4. Lithologic description of the lower slope sediments of the Bahamas Transect (Site 1003) separated into highstand and lowstand systems tracts deposits. The lowstand systems tracts include the transgressive systems tracts. Seismic-sequence boundaries were used to separate the highstand systems tracts from the lowstand systems tracts. Within a sedimentary sequence, the number of turbidite events varies from 0 to over 100, and in general more turbidites were seen in highstand deposits.
