Trishear kinematic model of fault-propagation folding and sequential development of minor structures: the Oupia anticline (NE Pyrenees, France) case study
S. Grelaud et al., Trishear kinematic model of fault-propagation folding and sequential development of minor structures: the Oupia anticline (NE Pyrenees, France) case study, B SOC GEOL, 171(4), 2000, pp. 441-449
The Oupia anticline is a fault-propagation fold located at the northeastern
tip of the Pyrenees. We show that this structure is suitably modelled usin
g the trishear kinematic model rather than the self-similar kink-band model
. In particular, the trishear model accounts well for the change in forelim
b dip along strike as well as for sequential overall thickening and then th
inning of the forelimb deduced from microtectonic analysis.
