Fracturing the Jura

Recent work on fraqctures in th Central Jura Mountains by two MAster students (Thibaud Rey (images) and Ahtos Tadé) have shown the complex fault pattern and its link to the regional tectonics as well as the protential reactivation in a changing stress field.


The main fault directions are often not those suspected from field geology and are revealed by investigating the digital elevation model:


The most difficult part in the interpretation is attributing the numerous and apparently randomly oriented faults to a distinct structural context and/or a reactivation:
