Abstract:
Five sites were drilled on the Iberia Abyssal Plain, west of the Iberian Peninsula. Four holes (897C, 897D, 899B, and 900A) yielded Eocene sediments that consist of turbidites and contourites. The Eocene section above the continental crust at Site 900 is continuous (from nannofossil Zones NP10 to NP20) and considerably expanded because of the site's relatively shallow depth, which remained consistently above the carbonate compensation depth (CCD). Sites 897 and 898, situated in deeper water above the ocean/continent transition, on the other hand, have noncontinuous, relatively short Eocene sections (from Zones NP14 to NP20 at Site 897 and from Zones NP19 to NP20 at Site 899). Nannofossils are abundant, diverse, and moderately to poorly preserved; they provide the primary means of dating the Eocene sediments recovered during Leg 149.
