Stratigraphy and Glacial-Marine Sediments of the Amerasian Basin, Central Arctic Ocean

摘要

Thirteen correlatable lithostratigraphic units are recognized in cores recovered from the central Artic Ocean. The stratigraphic units range in age from late Miocene to Holocene and can be correlated over several hundred thousand square kilometers. Six intervals of increased glacial ice-rafting are defined. A classification of glacial-marine sediment based on silt-clay histograms characterizes 4 classes. This is compared to non-Arctic glacial-marine sediment. (Author)
