19. UPPER NEOGENE AND QUATERNARY PLANKTONIC FORAMINIFERS FROM THE BLAKE OUTER RIDGE AND BLAKE-BAHAMA BASIN (WESTERN NORTH ATLANTIC), DEEP SEA
Four holes were drilled at two sites in the western North Atlantic during Deep Sea Drilling Project Leg 76. Thick Pliocene-Quaternary sediments were continuously cored in Holes 533 and 533A, located on the Blake Outer Ridge. A detailed biostratigraphic study of the upper Neogene and Quaternary strat...
