This study focuses on a geological section in the Jura Mountains across the villages of Travers, La Brévine in Switzerland, and Morteau in France. Field mapping was conducted to complement and densify existing data. A kinematically and geometrically consistent forward model has been developed to understand and interpret the observed surface structures. The proposed solution features a...

Multiple detachments during thin-skinned deformation of the Swiss Central Jura: a kinematic model across the Chasseral

Schori, Marc ; Mosar, Jon ; Schreurs, Guido

In: Swiss Journal of Geosciences, 2015, vol. 108, no. 2-3, p. 327–343

Combining field observations, cross-section area balancing techniques and kinematic forward modelling, we present new insights into the evolution of the Jura fold-and-thrust belt in the Chasseral area between Lake Biel and the Vallon de St-Imier, in the Canton of Bern, Switzerland. Our results show that the structures of the Chasseral area and the associated regional uplift can be explained by...
