Abstract:
The direction of bulk magnetic grain alignment within Tertiary and Cretaceous nannofossil oozes, marls, and volcaniclastic sandstones from the southeastern flank of the Walvis Ridge at hole 524 and Albian to Eocene deposits from 20 km north of the Walvis escarpment at hole 530A, recovered during Legs 73 and 75 of the International Program of Ocean Drilling (IPOD), has been determined from measurements of the magnetic susceptibility anisotropy. Depositional-style magnetic fabrics have been identified in a wide variety of sedimentary lithologies drilled at holes 524 and 530A. Assuming that the alignment mentioned above reflects the dominant transport direction at the time of sedimentation, useful information can be deduced concerning changes in sediment transport processes throughout this period. Thus, the magnetic fabric data confirm the existence of a preferred alignment of grain long axes at site 524 with an overall NW-SE orientation and at site 530 with an overall NE-SW orientation.
