SLICKENSIDE AND FAULT SURFACE KINEMATIC INDICATORS ON ACTIVE NORMAL FAULTS OF THE ALPINE BETIC CORDILLERAS, GRANADA, SOUTHERN SPAIN

Twenty four mesoscopic slickenside kinematic indicators are described here for the Pliocene-Quaternary active normal faults of the Alpine Be tic Cordilleras, Granada, southern Spain. The indicators are classifie d into twelve groups depending on the down- or up-slope asymmetric ori entation of features such as concavities, damaged versus sharp grain-b orders or step-edges, V-shaped markings, fractures, and trailed materi al. Seventeen of the indicators were not previously described in the l iterature. The new kinematic indicators include two types of asymmetri c grains, a carrot-shaped marking, six substructures of congruous and incongruous steps, trailed fault material, a drop-shaped figure, a V-s haped marking, three types of synthetic hybrid fractures with congruou s steps, and two varieties of pluck holes. We think that some of these kinematic indicators provide information on the amount of displacemen t, aseismic versus seismic slip rates, cataclastic flow, frictional we ar, or surface polishing.
