Abstract:
We report on benthic foraminifer results from Site 717 in the Distal Bengal Fan. Only 80 out of 380 samples contained useful benthic foraminifer information. However, we were able to identify four assemblages: 1. A present-day one dominated by Nuttallides umbonifera with some North Atlantic species; 2. An agglutinated fauna consisting of one species; 3. A reworked assemblage consisting of shallow-water forms; and 4. A reworked fauna consisting of an abundance of all kinds of forms including Cretaceous species. The reworked assemblage 4, we believe, represents a period when fan sediments were blocked from this area by east-west trending intraplate deformation. In the remainder of the core section, sedimentation appears to be dominated by Fan deposition with abundant terrestrial debris. In the infrequent pelagic intervals, it appears that abyssal water masses changed little since the late Miocene.
