  • Chronostratigraphy of the Hochterrassen in the lower Lech valley (Northern Alpine Foreland)

  • Ice-Rafted Erratics and Bergmounds from Pleistocene Outburst Floods, Rattlesnake Mountain, Washington, USA
    Zur Langanzeige Zusammenfassung Exotic ice rafted debris from the breakup of ice dammed glacial lakes Missoula and Columbia is common in slackwater areas along the 1 100 km route for outburst floods in the northwestern US A detailed analysis was performed at Rattlesnake Mountain which lay beyond the limit of the former ice sheet where an exceptionally high concentration of ice rafted debris exists midway along the floods path Here floodwaters temporarily rose to 380 m elevation forming short lived Lake Lewis behind the first substantial hydraulic constriction for the outburst floods near Wallula Gap Within the 60 km2 study area more than 2 100 erratic isolates and clusters as well as bergmounds were recorded Three quarters of erratic boulders are of an exotic granitic composition which stand in stark contrast to dark Columbia River basalt the sole bedrock in the region Other exotics include Proterozoic quartzite and argillite as well as gneiss diorite schist and gabbro all once in direct contact with the Cordilleran Ice Sheet to the north Most ice rafted debris is concentrated between 200 and 300 m elevation Far fewer erratics and bergmounds lie above 300 m elevation because of the preponderance of less than maximum

  • Erwägungen zur Korrelation mittelpleistozäner Relikte des Rheingletschers mit der Nordschweizer Stratigraphie
    Zur Langanzeige Zusammenfassung In the glaciation history of Switzerland Preusser Graf Keller Krayss Schlüchter 2011 is shown that two possibly three older glacials had happened before the well known glacials Würm Birrfeld and Riss Beringen These are the Habsburg and the Möhlin Glacials In this paper selected key regions in Southern Germany are analysed litho and morphostratigraphically This analysis enables us to find the two older glacials proved also at the Rhine Glacier The period of the Deckenschotter glaciations is followed by a time of striking fluvial erosion MPR Middle Pleistocene Reorganisation in the region of Lake Constance It is demonstrated that the glaciers of the subsequent Middle Pleistocene glacials exarated the overdeepened Lake Constance basin The oldest of these Becken Glacials is named Größtes Rheinisches Glazial GRG Möhlin in the northern part of Switzerland It corresponds to the Hosskirch introduced by Ellwanger 2003 In the northern Rhine Glacier region the most external glacial deposits belong to this glaciation Earlier in the northwestern part these deposits are interpreted as Riss Glacial but in the northeast as Mindel Glacial The GRG evidently must be older than Riss but younger than the Younger Deckenschotter Therefore Mindel in the northeastern region would be a Becken Glacial In the northern part of Switzerland the Habsburg Glacial nearly reached the extension of the Würm Glacial In the region of the Rhine Glacier references and or indications of the Habsburg Glacial could be found in a band width corresponding to the Würm but outside it as well In the northern region of the Rhine Glacier this vast glaciation has not been discovered up to now because the subsequent glacials Riss and Würm mainly destroyed its relics To classify the Greatest Rhine Glacial GRG as well as the Habsburg Glacial chronologically interpolated interglacials with time marks can
