Quaternary geology at Potter Peninsula, King George Island (South Shetland Islands, West Antarctica)

The succession of Quaternary deposits and morphological forms at Potter Peninsula. Maxwell Bay, King George Island (South Shetland Islands, West Antarctica) includes: (1) raised residual gravel and remains of marine abrasion surfaces, 97-118 m a.s.l. (Pleistocene); (2) marine (fjord-bottom) silty and sandy beds with bivalve shells (radiocarbon-dated at early Holocene); (3) highest raised marine terraces, 40-50 m a.s.l. (early Holocene); (4) older moraines - the Punta Batiza glaceir advance stage (mid-Holocene); (5) high raised marine terraces, 22-25 m a.s.l. (late Holocene); (6) low raised marine terraces, 7.5-12 m a.s.l., and raised marine beaches, 2-16 m a.s.l. (late Holocene); (7) younger moraines, outwash cones, kame terraces etc. - the Potter Cove glacier advance and retreat stages (latest Holocene). The Holocene isostatic land uplift at Potter Peninsula, is calculated at about 50 m.
