Late Pleistocene sea-level oscillations (MIS 10-2) recorded in shallow marine and coastal plain sediments of the southern Wanganui Basin, New Zealand

Glenn R Hughes, David M Kennedy



The northern Wanganui Basin, New Zealand, is one of the key global sites for understanding marine cyclic sedimentation during the Quaternary. This paper presents the first evidence of marine cyclic sedimentation from its central-southern parts. Sedimentological, micropalaeontological and palynological analyses on a 280-m-deep borehole encountered units dating back to MIS 10. The sequence includes four marine cycles spanning MIS 9-5, which are overlain by terrestrial fluvial aggradation surfaces dating from MIS 4-2. Each marine unit represents a progressively shallowing depositional environment from the mid-shelf to coastal plain. This is overlain by a terrestrial sequence of lowstand fluvial..
