The grain-size study and analyses of bulk sediment and clay mineral composition of samples collected from the dominant lithologies recovered at ODP Site 646, located on the northern flank of the Eirik Ridge (Labrador Sea), show variations indicating that contour-following currents, linked to Norwegian Sea Overflow Water (NSOW), have controlled sedimentation since the early Pliocene. These currents were influential until the early Pleistocene, despite the onset of major ice-rafting at about 2.5 Ma. A major mineralogical change occurred during the late Miocene: a decrease in the smectite to illite and chlorite ratio and a decrease of the crystallinity of smectites. This change indicates a renewing of the source rocks, which could result from an important hydrological change at this time. This change also is depicted by grain-size data that suggest the bottom current influence should be set earlier than the Pliocene. |
