Summary: A geomagnetic polarity zonation for the Late Miocene to the Quaternary has been determined from the sediments of the Kerguelen Plateau. Hole 745B on the south Kerguelen Plateau provided the excellent reversal sequence for the last 6 My including the Cobb Mountain event in the Matuyama Chron and the unidentified subchron in the Gilbert Chron. Hole 738C drilled a complete Cretaceous/Tertiary boundary. The volume magnetic susceptibility measurement around the Cretaceous/Tertiary boundary shows high values at the iridium-concentrated region. This supports the results by Worm and Banerjee (1987) that the high susceptibility and iridium concentration coincide at about the Cretaceous/Tertiary boundary. The limestone sequence at Hole 738C from the Turonian to Santonian stage shows a low paleolatitude (54S) compared to the present (64S). This paleolatitude is nearly the same as the Tertiary paleolatitude estimated from paleomagnetic poles of Antarctica. At Hole 742C in Prydz Bay a glacial sequence was penetrated to a depth of 316 mbsf. The magnetic susceptibility of this sequence correlated well with a changes of lithology. (Auth.)
