Abstract


Some of the contacts between the superimposed tectonic units in the region of Aguilas-Mazarrón, in the Betic Zone, are normal low-angle faults. They are associated with ductile-fragile and fragile extensional structures, which, from the Lower Miocene onwards, extensionely restructured the original pile of nappes. An analysis of these structures points to at least two directions of extension: one to the SSW, which gave rise to most of the extensional faults to be seen in the region and a later, weaker one to the ESE.
