A re-evaluation of the age and nature of Cenozoic erratics from McMurdo Sound, Antarctica

Late Eocene and Miocene marine erratics recovered from Minna Bluff and Mt. Discovery in Southern Victoria Land, Antarctica range from micritic cemented, variably sorted sandstones and conglomerates to impure micritic limestones. Lithologically, the erratics are similar to strata of the same age recovered from the MSSTS 1 hole in McMurdo Sound and indicate one or more periods of glacial erosion of marine strata in the Ross Sea during the last 15 m.y.No embarg
