Description
Summary:The purpose of this paper is to present data from a clay mineralogy investigation of the sediments analyzed for ice-rafted debris (IRD) from Hole 751A (see Breza, 1992, doi:10.2973/odp.proc.sr.120.136.1992). This data is significant in that the change in clay mineralogy may provide information about the Neogene evolution of climate and oceanic circulation near the Kerguelen Plateau and adjacent to Prydz Bay, Antarctica. Site 751 is located in the central part of the Raggatt Basin on the Southern Kerguelen Plateau in 1633.8 m of water (57°43.56'S, 79°48.89'E). The plateau is a structural high isolated from any continental input by means of turbidities or nepheloid transport. It is bounded to the northeast by the Australian-Antarctic Basin, to the southwest by the African-Antarctic Basin, and to the northwest by the Crozet Basin. To the south it is separated from Antarctica by the Princess Elizabeth Trough.Site 751 consists of two lithologic units. Unit I is composed of 40 m of upper Pleistocene to lower Pliocene diatom ooze with varying amounts of IRD and foraminifers. Unit II consists of 126 m of upper to lower Miocene diatom nannofossil ooze, with nannofossils as the primary sedimentary component. : X = present, - = not present
