Los macizos ultramáficos de Sierra de las Aguas y Sierra de la Robla como una ventana extensional (Béticas occidentales).

In the northernmost outcrops of ultramafic rocks of the Nappe de Los Reales (Se de las Aguas y de la Robla) it has been analysed the distribution of mineral facies and the minor structures associated to extensiona/ faults. A detachment zone is located between the Nappe de los Reales and the Malaguide Complex with some movement along the basal contact of the Alozaina Complex. The minor structures associated to extensional faults indicates a sense of shear towards the SSWSSE
