Lower Oligocene ice rafted debris of the Kerguelen Plateau@en

Appreciable lower Oligocene clastic detritus interpreted to be ice-rafted debris (IRD) was recovered at Ocean Drilling Program (ODP) Site 748 on the Central Kerguelen Plateau in the southern Indian Ocean. Site 748 is located in the western part of the Raggatt Basin, east of Banzare Bank at 58∞26.45'S, 78∞58.89'E (water depth = 1250 m). The physiologic and tectonic setting of the site and the coarse size of the material rule out transport of the elastics by turbidity currents, nepheloid layers, or wind. […]
