- The Zadnie Kamienne shear zone is a high-angle Riedel type shear zone (R'), exhibiting an antithetic sense of displacement, which may have developed synchronously with the nappe-thrusting of the Giewont Unit (High-Tatric Nappe). The amount of displacement along this zone is very low and does not explain the very intense deformation, which is of the same character as that at the base of the Giewont Unit (mylonitization, stylolitization and vein forming). The explanation of this phenomenon lies in the multiple activity of this zone, the change of the direction of movement and the important role of pressure solution in hydrothermal conditions responsible for dissolution creep, mass loss and stress relaxation. This kind of shear can be referred to as a "ravenous" shear zone. Neo-forming minerals accompanying these processes were applied as a temperature gauge. Simultaneous growth of albite and adularia indicates a temperature of about 350 degrees C. Chlorites accompanying them occur in two thermal episodes, the first of which indicating a similar temperature (292-357 C).
