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 Betic Cordilleras, Granada, southern Spain. The indicators are classified into twelve groups depending on the down- or up-slope asymmetric orientation of features such as concavities, damaged versus sharp grain-borders or step-edges, V-shaped markings, fractures, and trailed material. een of the indicators were not previously described in the literature. The new kinematic indicators include two types of asymmetric grains, a carrot-shaped marking, six substructures of congruous and incongruous steps, trailed fault material, a drop-shaped figure, a V-shaped marking, three types of synthetic hybrid fractures with congruous steps, and two varieties of pluck holes. We think that some of these kinematic indicators provide information on the amount of displacement, aseismic versus seismic slip rates, cataclastic flow, frictional wear, or surface polishing.
