Age models for long lacustrine sediment records using multiple dating approaches - An example from Lake Bosumtwi, Ghana

► New age model developed for the uppermost ∼150 ka of sediments from Lake Bosumtwi. ► The age model compares ages from 14C, OSL, U-series, paleomagnectic excursions. ► Agreement between independent dating methods supports the age-depth model. ► Paleomagnetic excursions and tuning offer opportunities for a longer chronology.
