Abstract
Analyses of intact orientated samples of incompetent fault rocks from thrusts within the Magura nappe in the Beskid Wyspowy Mountains indicate an arrangement of clay mineral plates parallel to numerous shears present in the rocks. Reconstruction of the development of the shears suggests several phases of formation. Maximum palaeotemperatures in the range 80 - 160°C were reconstructed from the fault zones.
