The chronostratigraphy of the latest Middle Pleistocene aeolian and alluvial activity on the Island of Hvar, eastern Adriatic, Croatia
Boreas - Tập 45 Số 1 - Trang 152-164 - 2016
Lara Wacha, Igor Vlahović, Sumiko Tsukamoto, Marijan Kovačić, Ozren Hasan, Davor Pavelić
Pleistocene aeolian sands and alluvial deposits can frequently be traced along the Mediterranean coast. Such deposits also exist along the eastern Adriatic coast and the nearby islands. Four stratigraphical sections of these deposits were studied on the Island of Hvar with the purpose of establishing a chronological framework of the aeolian–alluvial depositional system, using luminescence dating a... hiện toàn bộ
Timing of fluvial sedimentation in the Upper Rhine Graben since the Middle Pleistocene: constraints from quartz and feldspar luminescence dating
Boreas - Tập 47 Số 1 - Trang 256-270 - 2018
Yan Li, Sumiko Tsukamoto, Manfred Frechen, Gerald Gabriel
The Heidelberg Basin (HDB) hosts one of the thickest Quaternary sediment successions in central Europe. To establish a reliable Middle and Upper Pleistocene chronology for a recently drilled core from the depocentre of the Heidelberg Basin, we applied multiple luminescence dating approaches, including quartz optically stimulated luminescence (OSL), two feldspar post‐IR IRSL protocols using second ... hiện toàn bộ
The last Eurasian ice sheets – a chronological database and time‐slice reconstruction, DATED‐1
Boreas - Tập 45 Số 1 - Trang 1-45 - 2016
Anna L.C. Hughes, Richard Gyllencreutz, Øystein S. Lohne, Jan Mangerud, John Inge Svendsen
We present a new time‐slice reconstruction of the Eurasian ice sheets (British–Irish, Svalbard–Barents–Kara Seas and Scandinavian) documenting the spatial evolution of these interconnected ice sheets every 1000 years from 25 to 10 ka, and at four selected time periods back to 40 ka. The time‐slice maps of ice‐sheet extent are based on a new Geographical Information System (GIS) database, where we ... hiện toàn bộ
Palaeo-ice streams, trough mouth fans and high-latitude continental slope sedimentation
Boreas - Tập 32 Số 1 - Trang 37-55 - 2003
Colm Ó Cofaigh, Justin Taylor, Julian A. Dowdeswell, Carol J. Pudsey
Palaeoceanography of the Barents Sea continental margin, north of Nordaustlandet, Svalbard, during the last 74 ka
Boreas - Tập 45 Số 1 - Trang 76-99 - 2016
Teena Chauhan, Tine L. Rasmussen, Riko Noormets
We investigated gravity core HH11‐09GC from 488 m water depth at the northern Svalbard margin in order to reconstruct changes in Atlantic Water (AW) inflow to the Arctic Ocean. The study was based on the distribution patterns of benthic and planktic foraminifera, benthic and planktic oxygen and carbon isotopes, lithology and physical properties of the sediments. The core contains sediments from Ma... hiện toàn bộ
Dynamics of the Late Weichselian ice sheet on Svalbard inferred from high‐resolution sea‐floor morphology
Boreas - Tập 36 Số 3 - Trang 286-306 - 2007
Dag Ottesen, Julian A. Dowdeswell, Jon Y. Landvik, J. Mienert
High‐resolution bathymetric mapping of the fjords and continental shelf around the Svalbard archipelago shows an extensive pattern of large‐ and medium‐scale submarine landforms formed by differences in ice‐flow regimes. Mega‐scale glacial lineations, lateral moraines, transverse ridges and glaciotectonic features are superimposed on the large‐scale fjord, shelf and cross‐shelf trough morphology o... hiện toàn bộ
Seismic facies and architecture of ice‐contact submarine fans in high‐relief fjords, Troms, Northern Norway
Boreas - Tập 26 Số 4 - Trang 309-328 - 1997
Astrid Lyså, Tore O. Vorren
During the Late Weichselian, large marginal moraines were deposited in the Norwegian fjords. In Troms County these features are termed the Skarpnes and Tromsø‐Lyngen moraines, respectively, and have been mapped from land into the marine environment where they were formed as ice‐contact submarine fans. High‐resolution seismic data from several fjords have been studied and reveal a typical sediment ... hiện toàn bộ
10Be dating of Younger Dryas Salpausselkä I formation in Finland
Boreas - Tập 29 Số 4 - Trang 287-293 - 2000
Silvio Tschudi, Susan Ivy‐Ochs, Christian Schlüchter, Peter W. Kubik, H. Rainio
Boulders of the Younger Dryas Salpausselkä I (Ss I) formation west of Lahti, southern Finland, were sampled for surface exposure dating. The 10Be concentrations, determined by accelerator mass spectrometry, yield minimum exposure ages of 11 930 ± 950, 11 220 ± 890, 11 050 ± 910 and 11 540 ± 990 years, using recently published production rates scaled for latitude and elevation. This includes a corr... hiện toàn bộ
