Holocene raised beaches in the Lutzow-Holm Bay region, East Antarctica
Geomorphological investigations of raised beaches were conducted in the Lutzow-Holm Bay region to interpret the age and elevations of Holocene marine limits in relation to the glacial history of ice-free coastal regions around Antarctica. Prior to the Holocene, it is inferred, based on the recent da...
