Revised Lithostratigraphy and Structure mckskmned tectonics of the Eastern Graywacke Zone (Eastern Alps)

The Upper Austroalpine Nappe Complex of the eastern Graywacke Zone has been examined by field mapping, petrographical, structural, and geochronological studies. In contrast to previous studies evidence was found of four major Alpine thrust sheets which can be subdivi­ ded by their basement lithologies, their Late Paleozoic to Triassic cover sequences, and the extent of pre-Alpine metamorphism. We distinguish between the following thrust sheets (from footwall to hangingwall): The Veitsch nappe, the Silbersberg nappe, the Kaintaleck nappe, and the Noric nappe.
