The preglacial Worth Point Formation sediments and overlying Duck Hawk Bluff Formation sediments (including marine and glacial deposits laid down during the Banks Glaciation) have magnetically reversed directions and therefore are probably of Matuyama age (<730 Ka). Deposits of the younger Morgan Bluffs and Cape Collinson interglacials and Thomsen and Amundsen glaciations are normally magnetized and therefore of Brunhes age (<730 Ka). These sesults provide the first minimum-age estimate for the Worth Point Formation organic deposits and for the Banks Glaciation, the oldest and strongest glaciation recorded in the western Arctic. The new time framework will facilitate correlations with terrestrial sequences of Beringia and early Pleistocene Arctic Ocean sediments. This content is PDF only.
