El Complejo Alpujárride de La Axarquía: Zonas de cizalla dúctiles a escala cortical y pliegues recumbentes asociados
Alonso Chaves, Francisco Manuel
; Orozco, Miguel (Universidad de Huelva, 2012)
En las Unidades Alpujárrides que afloran en La Axarquía se observan pliegues recumbentes con distintas orientaciones. En algunas unidades, como en las de Tejeda y Benthomiz, se describen flancos inversos kilométricos en ... -
El Sistema de Fallas Extensionales de La Axarquia (Sierras de Tejeda y La Almijara, Cordilleras Béticas)
Alonso Chaves, Francisco Manuel; Orozco, Miguel (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 ... -
Fábrica de cuarzo y cabalgamientos hacia el ENE en Sierra Nevada y Sierra de los Filabres (Cordilletas Béticas)
(Sociedad Geológica de España, 1986)From microstructures and quartz c-axis fabric analysis the characterization of the «Mulhacen/Veleta ductil shear zone» is made. The existence of important eastward directed thrustings predating the S-N movements is inferred. ... -
Fallas de despegue extensional miocenas en el área de Sierra Tejeda (Béticas centrales)
Alonso Chaves, Francisco Manuel; García Dueñas, V.; Orozco, Miguel (Sociedad Geológica de España, 1993)
In the Sierra Tejeda area, NE Malaga, the existence of detachments and low angle normal faults has been recognized. The faults developed during three Miocene extensional events of AquitanianBurdigalian, probably Langhian ... -
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 ... -
La falla normal de bajo ángulo de Tejeda: un ejemplo de la deformación miocena en las Béticas centrales
Alonso Chaves, Francisco Manuel; Orozco, Miguel; García Dueñas, V.; Mayoral Alfaro, Eduardo (Sociedad Geológica de España, 1994)
The existence of a major extensional fault in Sierra Tejeda, Central Betics, developed during the middle Miocene, is evidenced. The Tejeda, Venta de Palma, Bentomiz and Alcaiceria units make up the hanging-wall o f the ... -
Late extensional shear zones and associated recumbent folds in the Alpujarride subduction complex, Betic Cordillera, southern Spain
Orozco, Miguel; Alonso Chaves, Francisco Manuel; Platt, J. P. (Universitat de Barcelona, 2017)
The existence in the Alpujarride Complex (Betic Cordillera, southern Spain) of a relatively continuous extensional event (following crustal thickening) is based on detailed structural studies and is consistent with the ... -
Middle Miocene extensional faulting events and Alpujarride Units in the Central Betics
(Sociedad Geológica de España, 1993)In the Central Betics, the Alpujarride Complex is made up of units which result from the dismembering of pre-Miocene fold nappes during a Late Burdigalian (?)-Langhian extensional event -
El sentido de desplazamiento de los Mantos Nevado-Filábrides
(Sociedad Geológica de España, 1987)The Veleta Unit and the Mulhacen nappe Group (Calar Alto and Bédar-Macael Nap pes) make up the Nevado-Filábride Complex. The westward movement of the both nappes occurred along NW to WSW trajectories. In the Sierra Nevada, ... -
Termobarometría en los gneises de la unidad extensional de Bentomiz, Complejo Alpujárride (Béticas centrales)
Alonso Chaves, Francisco Manuel; Pascual Martínez, Emilio; Orozco, Miguel (Sociedad Geológica de España, 1994)
In the gneis of the Bentomiz extensional unit (Sierra Tejeda area), the alpine metamorphic evolution was studied. These rocks show high pressure-high temperature (HP/HT) assemblages. An extensional deformation before Neogene ... -
La zona de cizalla del contacto entre el grupo de mantos del Mulhacén y la unidad del Veleta (Sierra Nevada y Sierra de los Filabres, Andalucía)
(Sociedad Geológica de España, 1986)The existence of an important ductil shear-zone developed in relation with the emplacement of the Mulhacen nappes group on the Veleta Unit (Betic Cordilleras) is manifested. The overlaping in the ENE sense is over 200 km ...
