Abstract
Concentrations of 10Be have been measured in sediments and loess from the Wanganui region, New Zealand, and in soils from the Roberts Massif, Antarctica. The Wanganui sediments show a clear enhancement of 10Be over the period of the Brunhes-Matuyama geomagnetic field reversal, although the cause of the enhanced signal is not attributed directly to the field reversal event. Data from the Antarctic soils are consistent with an age of the landscape of the order of 12 million years.
