The fracture pattern of the Sant Corneli Bóixols oblique inversion anticline (Spanish Pyrenees)

► We collected fracture data in an oblique inversion anticline. ► Fractures are neither parallel nor perpendicular to the strike of the study fold. ► Fractures mostly developed during Early Cretaceous extension. ► Syn-inversion fractures are parallel and perpendicular to the shortening direction. ► Inherited extensional fractures were reactivated as strike-slip faults.
