  • Late Quaternary Evolution of the Western Nordenskiold Land
    POLISH POLAR RESEARCH 14 3 259-274 1993 Andrzej MUSIAŁ, Bogdan HORODYSKI and Krzysztof KOSSOBUDZKI Department of Geography and Regional Studies Warsaw University Krakowskie Przedmieście 30 00-927 Warszawa, POLAND Late Quaternary evolution of the western Nordenskiold Land ABSTRACT: Relief of Svalbard is an effect of varied morphogenetic, exogenic and endogenic processes. Tectonic and glacioisostatic movements of the Earth crust have occurred many a time in this region. Glacial, marine and periglacial features are particularly common. During the Late Quaternary the western Nordenskiold Land underwent several sea transgressions, followed by glacier advances. Basing on erratics of crystalline rocks transported by sea ice, past sea levels have been established up to 250 m a.s.l. Marine terraces above 60 m a.s.l. date back to the Late Pleistocene, the lower ones are of the Holocene age. Key words: Arctic, Spitsbergen, Quaternary evolution. The western Nordenskiold Land between Bellsund, Greenland Sea, Isfjorden and Gronfjorden is a highly diversified area if its geology and landscape are concerned (Musiał 1983, 1984, 1985, Musiał et al. 1990). The paper presents research on landscape evolution in polar conditions which has been carried out in western Spitsbergen by academic expeditions organized by the Department of Geography and Regional Studies of the Warsaw University in 1978, 1980, 1985 and 1988. Seaside plains of Vast Langnes, Isfjorden and Vardeborg stretch westwards into an abrasive platform in which there are lowerings, consistent with the present fiords (Fig. 1). The plains are delimited in the east by two parallel mountain massifs with prominent peaks of Griegfjellet (778 m), Systemafjellet (744 m), Ytterdalsgubben (901 m), Ytterdalssata (593 m), Vardeborg (588 m), Qvigstad- fjellet (770 m), Foldtinden (730 m) and Flynibba (745 m a.s.l.).

  • Quaternary Glaciation History of Northern Switzerland
    Quaternary Science Journal GEOzOn SCiEnCE MEDiA Volume 60 / number 2–3 / 2011 / 282–305 / DOi 10.3285/eg.60.2-3.06 iSSn 0424-7116 E&G www.quaternary-science.net Quaternary glaciation history of northern switzerland Frank Preusser, Hans Rudolf Graf, Oskar keller, Edgar krayss, Christian Schlüchter Abstract: A revised glaciation history of the northern foreland of the Swiss Alps is presented by summarising field evidence and chronologi- cal data for different key sites and regions. The oldest Quaternary sediments of Switzerland are multiphase gravels intercalated by till and overbank deposits (‘Deckenschotter’). Important differences in the base level within the gravel deposits allows the distin- guishing of two complex units (‘Höhere Deckenschotter’, ‘Tiefere Deckenschotter’), separated by a period of substantial incision. Mammal remains place the older unit (‘Höhere Deckenschotter’) into zone MN 17 (2.6–1.8 Ma). Each of the complexes contains evidence for at least two, but probably up-to four, individual glaciations. In summary, up-to eight Early Pleistocene glaciations of the Swiss alpine foreland are proposed. The Early Pleistocene ‘Deckenschotter’ are separated from Middle Pleistocene deposition by a time of important erosion, likely related to tectonic movements and/or re-direction of the Alpine Rhine (Middle Pleistocene Reorganisation – MPR). The Middle-Late Pleistocene comprises four or five glaciations, named Möhlin, Habsburg, Hagenholz (uncertain, inadequately documented), Beringen, and Birrfeld after their key regions. The Möhlin Glaciation represents the most extensive glaciation of the Swiss alpine foreland while the Beringen Glaciation had a slightly lesser extent. The last glacial cycle (Birrfeld Glaciation) probably comprises three independent glacial advances dated to ca.

  • The Pre-Elsterian Valley System in the Western Sudetes, Southwestern Poland, and Its Later Transformation
    Geologia Sudetica, 1998, 31:317-328. The pre-Elsterian valley system in the Western Sudetes, southwestern Poland, and its later transformation Marek Michniewicz Panstwowy Instytut Geologiczny, Oddziai Dolnoslqski, Jaworowa 19, 53-122 Wrodaw, Poland Key words: buried valleys, fluvial pattern, glacial deposits, Elsterian glaciation Abstract This paper presents a reconstruction of the pre-Elsterian fluvial pattern in the Western Sudetes Mts using borehole and geophysical data. These valleys were blocked by the advancing Elsterian ice sheet, enabling the proglacial lakes to be formed, and most of them were later covered by the ice sheet which entered into the mountain interior. The valleys are now filled with 5-15 m of 'pre-glaciaP fluvial gravels and a generally thick glacial series. The latter comprises a till and glaciofluvial and glaciolacustrine sediments, including varved clay. The former valleys occur along the axes of the present-day valleys or at their margins, or occur in watershed areas which have been recently abandoned. Post-Elsterian changes in valley pattern is due to the filling of old valleys and epigenetic incision of new valleys along the tributary valleys. The valley fragments which preserved their former position were deeply incised, with the almost complete removal of older deposits. Some fault activity has been documented for that time in the marginal zone of the Sudetes Mts. The Saalian ice sheet only entered the marginal part of the Sudetes Mts, and hydrographic changes from that time are smaller. Manuscript received 15 April 1998, accepted 30 October 1998.

  • 1. Lithostratigraphy, Palaeopedology and Geomorphology
    Eiszeitalter u. Gegenwart Band 23/24 Seite 268-280 Öhringen/Württ., 15. Oktober 1973 B. Foreland of the Alps 1. Lithostratigraphy, Palaeopedology and Geomorphology by HANS GRAUL, Heidelberg *) With 2 figures 1. Introduction The northern Alpine foreland, as far as it belongs to the drainage systems of the Danube and the Lake Constance-Rhine Rivers and within the political boundaries of the Federal Republic of Germany will be dealt with in this short summary. The latest papers concerning Quaternary research in the West German Alpine foreland can be found in the first ten references of the bibliography. In addition, these reports can be drawn on for references to older literature. The attempt of RICHMOND (1970) to compare the qua­ ternary stratigraphy of the Alps with the Rocky Mountains will be also gone into. As is well known, PENCK (1901—1909), who, together with BRÜCKNER, discovered the four glaciations of the Alps, named them after the foreland rivers Würm, Riss, Mindel and Günz. Everyone also has cognizance of the didactical principle, whereby the alpha­ betical sequence was applied to rivers which were not too small and at the same time allochthonous to the foreland. It is a fact that PENCK & BRÜCKNER, with their strati- graphical principle of tetraglacialism, were able to connect loci typici, which are still useful, for the glacial series of one of the four ice ages in the area of its like-named river. The present common names for those ice ages divided by true interglaciations have been internationally accepted through the use of the PENCK-BRÜCKNER names for the last (Würm) and the three preceding ones.

  • SURFICIAL GEOLOGY of the SYRACUSE FIELD AREA by Ernest
    SURFICIAL GEOLOGY OF THE SYRACUSE FIELD AREA by Ernest H. Muller Introduct ion The following notes provide a frame of reference for field trips in the Syracuse area, planned for the 36th Annual Meeting of the New York State Geologi­ cal Association, May 8-10, 1964. These trips range from Rome in the east to Mar­ cellus in the west and from Boonville in the north to Tully in the south. No effort is made to provide uniform treatment throughout the area of concern; rather, relationships at certain stops are developed in detail, whereas others are treated only in general terms. Regional relationships Syracuse is located in the border zone between two major physiogra?hic prov­ inces. North of the city, undulating plains of the Ontario Lowland stretch away to Lake Ontario. Streaml ined ridges of glacial till give much of the lake plain its distinctive topographic texture. South of Syracuse, the land rises more than a thousand feet within a few miles, forming the north-facing margin of the Appala­ chian Uplands. Northeast of Syracuse the Oneida basin, an eastward extension of tre O~tario Lowland, isolates the Tug Hill Plateau from the Appalachian Uplands to which it is physiographically related. In unglaciated parts of Pennsylvania and lightly glaciated parts of southern New York, physiographic history is recorded in accordance of summits. Following late Paleozoic regional upl ift, the Syracuse area presumably experienced similarly long erosion that beveled the southward dipping strata. Because intensity of glacial scour increased northward across New York, summits south of Syracuse are rounded and reduced in elevation, retaining only approximate summit accordance.

  • The Last and Penultimate Glaciation in the North Alpine Foreland: New Stratigraphical and Chronological Data from the Salzach Glacier

Salcher a, , Reinhard Starnberger b, Joachim Gotz€ a a Department of Geography and Geology, University of Salzburg, Hellbrunner Strasse 34, 5020 Salzburg, Austria b Institute for Geology and Palaeontology, Leopold-Franzens University of Innsbruck, Innrain 52, 6020 Innsbruck, Austria abstract Keywords: The Northern Alpine Foreland was repeatedly covered by massive piedmont glaciers during Quaternary Stratigraphy glacial maxima. The Salzach palaeoglacier lobe (Austria/Germany) was the easternmost of a series of Lithofacies Pleistocene piedmont glaciers entering the foreland through major alpine valleys. It covered an area of Luminescence dating more than 1000 km2 during at least four glacial maxima. Here we aim to bring more light into its history North Alpine Foreland Glacier lobe by analyzing multiple drill log data, two major outcrops, topographic data, and absolute chronologies of Glaciofluvial sediments sediments. Stratigraphic and lithofacies investigations are focused on proximal (i.e. near the lobe axis) and distal (i.e. near terminal moraine) deposits of the Salzach glacier lobe. The glacial carving into the Miocene bedrock occurred during early glacial maxima and was rather uniform across the lobe with larger values only in the proximal parts of the glacier. More than 100 m of accumulated sediments during later glacial maxima indicate a change in ice-sheet dynamics and a characteristic sequence development which varies from proximal to distal lobe positions. New luminescence ages suggest a depositional focus at the penultimate glacial period while the impact of the LGM was rather minor.
