Esfuerzos recientes en el sector sudoriental de la Depresión de Granada (Cordillera Bética central)

Abstract

The analysis of the seismic activity and the microtectonic study of outcrops located in the southeastern Granada Depression show that the stress states have been heterogeneous from the Upper Miocene up to the present. NE-SW extensional stresses may be associated to the activity of NW-SE oriented normal faults, that coexist with NW-SE compressional stresses, related to the development of NE-SW oriented folds. Other stress ellipsoids have been also determined, generally with the same orientation of the ellipsoid main axes. The stress states calculated are compatible with the uprising of the basement of the Granada Depression and with the crustal thickening process related to Africa-lberia convergence
