Magnetic and petrographic properties of ODP Site 120-747 (Table 1), supplement to: Heider, Franz; Körner, Ulrike; Bitschene, Peter Rene (1993): Volcanic ash particles as carriers of remanent magnetization in deep-sea sediments from the Kerguelen Plateau.

Carbonate sediments from the Kerguelen Plateau (ODP Leg 120) of Eocene to Pliocene age were investigated with rock magnetic, petrographic and geochemical methods to determine the carriers of remanent magnetization. Magnetic methods showed that the major magnetic minerals were titanomagnetites slightly larger than single domain particles. Submicrometre to micrometre-size grains of titanomagnetite were identified as inclusions in volcanic glass particles or as crystals in lithic clasts. Volcanic fallout ash particles formed the major fraction of...
