Estructura profunda del sector central de las Cordilleras Béticas.

Resumen

The analysis of the crustal structure of the central sector of the Betic Cordilleras, by means of deep reflection seismic profiles and gravimetry, shows that the Moho is nearly planar. The continental crust of the Iberian Massif probably continue below the Betic Cordilleras. The boundary of the Betic Cordilleras crust and the thin crust ofthe A/boran Sea is made along a narrow E-W trending band where the Moho probably dips more than 60s N. This band is located 10 to 20 Km north of the coast line. The crust in the Betic Cordilleras has detachments, and the large folds with northward vergence, related to the mam topographic features of the Internal Zones, do not deform the deep reflectors. The mam crustal structures shown in the geophysical models are consistent with the oblique convergent movement between the Eurasian and African plates
