Keuper (Late Triassic) sediments in Germany - indicators of rapid uplift of Caledonian rocks in southern Norway
K/Ar ages of detrital Keuper micas in the Central European Basin provide new information about the provenance of siliciclastic sediments. All samples of the Erfurt Formation (Lower Keuper) and the Stuttgart Formation (Middle Keuper) indicate Caledonian (445 - 388 Ma) ages. These sediments originate...
