Abstract: | The Paleozoic of Graz is an isolated nappe complex of about 1,500 km2 size and belongs to the Austroalpine units of the eastern European Alps. Despite more than 500 publications on stratigraphy,
paleontology and local structure, many aspects of the internal geometry of this complex as a whole remained unclear. In this
contribution, we present integrated geological profiles through the entire nappe complex. Based on these profiles, we present
(1) a simplified lithological subdivision into 13 rock associations, (2) a modified tectonostratigraphy where we consider
only two major tectonic units: an upper and a lower nappe system and in which we abandon the traditionally used facies nappe
concept, and (3) a modified paleogeography for the whole complex. Finally, we discuss whether the internal deformation of
the Paleozoic of Graz is of Variscan or Eo-Alpine age and which of the published models best explain the tectonic evolution
of the Paleozoic of Graz. |
