AB Geometric and kinematic analysis of Pyrenean folds, cleavage and thrusts is carried out in several exceptionaloutcrops of the Eocene flysch at Isaba (Navarra, Spain). Distribution, orientation and cross-cut relationshipsbetween these structures suggest that they are roughly coeval and co-genetic, the total deformation beingdistributed into different ductile and brittle mechanisms. The footwall of the Sierra de Arrigorrieta thrustshows a set of harmonic folds with axial-plane cleavage; an overall flattening l l = 0,7-0,85 hasbeen estimated from their profile-section geometry. The hanging-wall shows more heterogeneousdeformation: minor thrusts, complex duplexes, and non-harmonic folds with sharp changes in orientationand density of cleavage linked to thrust ramps. The structural position and the presence of some cuspatelobatefolds (mullions) in turbidite levels suggest an early deformation even previous to the Larra thrustsystem
