Alte Strandlinien des Pleistozäns in Nordamerika und Europa

Abstract. Apart from the Silver-Bluff-beach which is said to belong to the postglacial climatic optimum, there are on the Atlantic coast of USA at least three higher old beaches: the Pamlico beach in about 25 feet, the Wicomico beach in about 100 feet, and the Okefenokee beach in ±150 feet. Connected with the Pamlico beach is the marine Pamlico or Cap May formation. The Gardiners Clay of Long Island and the southern New England States seems to be the northern continuation. All these formations belong to the Sangamon Interglacial and are the equivalent of the European Eem deposits. The age of the higher beaches (Wicomico, Okefenokee) is still incertain. The Wicomico beach could be an equivalent of the Tyrrhenian I in Europe. Equivalents of the Okefenokee beach (about 45 m) have been found in Western Europe (e.g. in Portugal); but we don't know, whether they belong to the Günz/Mindel- or the Mindel/Riß-Interglacial.
