Description
Summary:Correlation of main ice sheet limits in northern continental Europe during Late Weichselian is presented, based on available data concerning occurrence of ice-marginal formations and their radiometric dating. The Late Weichselian maximum ice sheet limit was time-transgressive in this region what has been primarily caused by diversified dynamics of the ice sheet body, composed of several paleo-ice streams developed to the south of the Baltic Basin. The Late Weichselian maximum ice sheet limit was the earliest in Denmark, Germany and western Poland (24-22 cal kyrs BP) but it was younger to the east and northeast (20-17 cal kyrs BP). Such age difference resulted from demarcation of the ice sheet maximum limit by successive glacial advances. They were partly due to varied distances from the ice divide in Scandinavia, making the ice sheet margin to reach its terminal position in different time. Both during the maximum and the most deglacial phases the glacial limits indicated lobate patterns of marginal formations, reflecting outlets of paleo-ice streams within the southern and southeastern fringe of the Scandinavian Ice Sheet to the south of the Baltic Sea basin. During deglaciation numerous readvances and standstills of the ice sheet margin occurred but due to diversified structure of the ice sheet body, its peripheries behaved differently, even in neighboring regions. Se presenta la correlación de los principales límites del inlandsis en la Europa continental septentrional durante el final del Weichseliense, a partir de los datos disponibles sobre la formación de masas de hielo marginales y su datación radiométrica. La máxima extensión de finales del Weichseliense fue transgresiva en esta región, debido a la diversa dinámica de la masa de hielo, compuesta por varios cursos de hielo desarrollados hacia el sur de la cuenca Báltica. El límite máximo del hielo se alcanzó primero en Dinamarca, Alemania y Polonia Occidental (24-22 cal ka BP), pero fue más reciente hacia el este y nordeste (20-27 cal ka BP. Esta ...
