Název v původním jazyce

Deciphering the Variscan tectonothermal overprint and deformation partitioning in the Cadomian basement of the Teplá-Barrandian unit, Bohemian Massif

Popis výsledku v původním jazyce

The Teplá-Barrandian unit (TBU) has long been considered as a simply bivergent supracrustal 'median massif' above the Saxothuringian subduction zone in the Variscan orogenic belt. This contribution reveals a much more complex style of the Variscan tectonometamorphic overprint and resulting architecture of the Neoproterozoic basement of the TBU. For the first time, we describe the crustal-scale NE-SW-trending dextral transpressional Krakovec shear zone (KSZ) that intersects the TBU and thrusts its highergrade northwestern portion severely reworked by Variscan deformation over a southeastern very low grade portion with well preserved Cadomian structures and only brittle Variscan deformation. The age of movements along the KSZ is inferred as Late Devonian (~380-370 Ma). On the basis of structural, microstructural, and anisotropy of magnetic susceptibility (AMS) data from the KSZ we propose a new synthetic model for the deformation partitioning in the Teplá-Barrandian upper crust in respo
