Sediments of the Lomonosov Ridge and Makarov Basin: A Pleistocene Stratigraphy for the North Pole

摘要

Cores from the Canadian LOREX (Lomonosov Ridge Experiment) project provide a Pleistocene stratigraphy for the North Pole. Twelve sedimentary units distinguish the past 500,000 years of the Lomonosov Ridge and Makarov Basin. A new formation, the Makarov Basin Formation, is proposed. Correlation with Alpha Ridge stratigraphy is possible and glacial and interglacial stages are defined by sediment and faunal comparisons.
