Late Quaternary carbonate and isotope stratigraphy, subantarctic Site 594, southwest Pacific.

Abstract

The late Quaternary sequence off eastern South Island, New Zealand, consists of approximately 100 m of alternating bluish gray pelagic oozes and greenish gray hemipelagic oozes that extend uninterruptedly back to the Brunhes/Matuyama boundary (0.73 Ma). A very high resolution (approximately 2400 yr.) record of sediment texture, calcium carbonate content, and planktonic and benthic foraminiferal oxygen and carbon isotope composition demonstrates an in-phase cyclical fluctuation between the sedimentary parameters that closely correspond to the pelagic-hemipelagic sedimentation cycles and the isotope composition. -from Authors
