Mass accumulation rates of the non-authigenic inorganic crystalline ( eolian) component of deep-sea sediments from the western Mid-Pacific Mountains, Deep Sea Drilling Project Site 463 ( DSDP).

Abstract

Elevated regions in the central parts of ocean basins are excellent for study of accumulation of eolian material. The mass-accumulation rates of this sediment component appear to reflect changes in the influx of volcanic materials through the Early Cretaceous to Recent history of DSDP Site 463, on the Mid-Pacific Mountains. Four distinct episodes of eolian accumulation occurred during the Cretaceous. Upper Miocene to Recent sediments record an upward increase in accumulation rates. The late Pliocene- Pleistocene peak may reflect the change to glacial-wind regimes, as well as an increase in volcanic source materials. -from Authors
