El Sistema de Fallas Extensionales de La Axarquia (Sierras de Tejeda y La Almijara, Cordilleras Béticas)
(Sociedad Geológica de España, 1997)The faults of La Axarquia Extensional System show a listric geometry. They cut across the uppermost alpujarride units and strongly contribute to the NW-SE mountain trend defined by the Tejeda-Almijara sierras. The main ... -
Estructura del Campo de Dalías a partir de datos gravimétricos y sísmicos
(Sociedad Geológica de España, 2004)The analysis of new gravity data and multichannel seismic profiles of the Campo de Dalías give new insight about the main features of the deep structure. The progressive development since the Tortonian of folds determine ... -
Estructura profunda del sector central de las Cordilleras Béticas
(Sociedad Geológica de España, 1994)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 ... -
Estructuras extensionales en los materiales Aipujárrides al E de Málaga (Sierra Tejeda, Cordilleras Béticas)
(Sociedad Geológica de España, 1992)The main deformation in the Tejeda and Canillas de Albaida Units is produced during a heterogeneous simple shearing regime that generates a planar-linear fabric. This simple shear has a topto-the-westsouhwest sense of ... -
Evolucìón petrogenética del magmatismo bàsico mesozoico en las Zonas Externas de las Cordilleras Béticas (S. España)
(Sociedad Geológica de España, 1996)Mesozoic basic magmatism from the External Zones of the Betic Cordilleras consisted of two magmatic events. The first one began at the end of the Triassic and the second developed during the Jurassic. Whole-rock geochemical ... -
Formación de grafito a partir de fluidos: La mineralización de Huelma (Jaén)
(Sociedad Geológica de España, 1996)The volcanic-hosted graphite mineralization of Huelma Qaén) has been studied in order to stablish the mineralogical characteristics and mechanisms of formation. The graphite is highly ordered (as revealed by XRD and Raman ... -
Generaciones de cabalgamientos y pliegues recumbentes en los Mantos Alpujárrides entre Ronda y Almería, Cordilleras Béticas
(Sociedad Geológica de España, 1987)Synmetamorphic thrust nappes, related to the Los Reales Crustal Thrust within the Alpujarride Nappes, moved in an ENE or NE direction. A subsequent movement took place in a northerly direction and large fold nappes were ... -
