Late Cenozoic Stratigraphy for Glacial-Marine Sediments of the Eastern Alpha Cordillera, Central Arctic Ocean

摘要

Fifteen lithostratigraphic units are present and correlatable in 48 sediment cores recovered from the eastern flank of the Alpha Cordillera, central Arctic Ocean. The lithostratigraphy has been designated to facilitate correlation with established units of the central portion of the Amerasian Basin. Based on the extrapolation and interpolation of sedimentation rates from paleomagnetic reversals, calculated ages indicate a stratigraphic section ranging from early Pliocene to Holocene. The oldest sediment recovered yielded an age of 3.54 m.y. Keywords include: Stratigraphy, Eastern Alpha Ridge, Glacial-marine sediment, and Paleoceanography.
