Abstract
A spaced pressure-solution cleavage related to Alpine thrusts in Mallorca (Balearic Isles) is deformed by several sets of shear planes and minor folds. All these structures formed synchronously, related to the thrust sheet movement. Shear plane sets show different orientations irrespective of the cleavage disposition. Slip along these shear planes shows that deformation did not result in plane strain. Minor fold axes show a wide range of orientations. Neither folds nor shear planes enable us to directly deduce the sense of thrust motion, indicating that these criteria must be used with care. Previous strain characterization is required for definite conclusions to be reached.
