Syntectonic fluid flow and deformation mechanisms within the frontal thrust of a foreland fold-and-thrust belt: Example from the Internal Jura, Eastern France

Structural mapping and microstructural analyses are combined with stable, clumped, and radiogenic isotopes to unravel deformation mechanisms and syntectonic fluid flow during upward propagation along the frontal thrust (Fuans thrust) of the internal part of the Jura fold-and-thrust belt. The Fuans thrust cuts through Upper Jurassic-Lower Cretaceous carbonate deposits, branches into two splays, and generates a system of fault-propagation folds....
