Quaternary and Cretaceous sediments between Velký Osek, Veltruby and Sendražice
Abstract
Revision of late Pleistocene fluvial sediments as well as of the underlying Cretaceous sediments were made in the vicinity of Velký Osek near Poděbrady (Central Bohemia). Based on borehole data, two Pleistocene fluvial accumulations with different base level have been recognized. Holocene incision of the Labe River into Pleistocene accumulation also took place. The depth of the incision under alluvial muds is, however, unknown. Upper Cretaceous sediments have been reinterpreted in the area. A glauconitic bed has been recognized at the Cenomanian/Turonian boundary. Presumed existence of the Poděbrady fault is indicated from different position of the glauconitic key bed in boreholes.
