In this study we test whether principal components of the strain rate and stress tensors align within Switzerland. We find that 1) Helvetic Nappes line (HNL) is the relevant tectonic boundary to define different domains of crustal stress/surface stra

International audience; We describe a singular structure in Upper Cretaceous rocks of the Eaux-Chaudes massif of the western Pyrenees, consisting of a kilometre-scale fold nappe with a sheared overturned limb. High ductile strain attests a deformatio

The importance of tangential motion in the Central Alps: Kinematic analysis and Rb-Sr dating of mylonitic rocks from the Pennine nappes in the eastern Central Alps

Autor: Johannes Glodny, Uwe Ring

Publikováno v: Earth-Science Reviews

We discuss the important role of tangential stretching in the Central Alps highlighting that the Alps are a truly three-dimensional orogen. A review of pressure-temperature (P-T) conditions allows us to define three major breaks in metamorphic pressu

The Structural Landscapes of Central Switzerland

Autor: O. Adrian Pfiffner

Publikováno v: World Geomorphological Landscapes ISBN: 9783030432010

Both, landforms and landscape of Central Switzerland mimic the structure of the underlying bedrock rather closely. As an example, Stanserhorn, Buochserhorn, and Mythen can be mentioned where Jurassic carbonates of the Klippen nappe form steep peaks a

International audience; Understanding the rheology of orogenic wedges requires the knowledge of the structural and thermal evolution of collisional units. In this study, we document the maximum temperature reached by the sedimentary cover nappes of t

Thermochronometry Across the Austroalpine-Pennine Boundary, Central Alps, Switzerland: Orogen-Perpendicular Normal Fault Slip on a Major 'Overthrust' and Its Implications for Orogenesis

Autor: Kenneth A. Farley, Michael A. Cosca, Jason B. Price, Brian P. Wernicke

Publikováno v: Tectonics. 37:724-757

Fifty-one new and 309 published thermochronometric ages (nine systems with closure temperatures ranging from ~450 to 70°C) from the Graubunden region of the Central Alps demonstrate that a pronounced thermal mismatch between the Austroalpine allocht

Tectonic inheritance and kinematic strain localization as trigger for the formation of the Helvetic nappes, Switzerland

Autor: Stefan M. Schmalholz, Arthur Bauville

Publikováno v: Swiss Journal of Geosciences. 110:523-534

The Helvetic nappes in Switzerland consist of sediments, which have been sheared off and thrust over the crystalline basement of the European passive continental margin during Alpine orogeny. Their basal shear zones usually root above the external cr
