Two deep-sea cores, GIK13891 and GIK13291, retrieved off Mauretania (NW Africa) from the top of a ca. 250 m high seamount and from the seamount's foot were studied. Planktonic foraminifera oxygen isotope records in conjunction with 14C ages in the upper core sections were used to establish a stratigraphy. Sedimentological studies of both cores focused on the occurrence and abundance of giant grains of up to 1500 µm. Three possible transport ways for those giant grains are being discussed:a) transport by turbidity currentsb) erosion from the seamount topc) eolian delivery.The sedimentological results, including SEM pictures, point mainly to erosion and additional eolian delivery of the giant grains.
