Castillo, A.; Vallejos, Ángela; Cerón García, Juan Carlos
(Sociedad Geológica de España, 1993)
The waters of the Almanzora basin have very different chemistry according to the hydrogeological context; the mineralization is between 0,4 and more than 6 g/i; the hydrochemical facies is usually . calcic, bicarbonated ... -
Sedimentologia del sector occidental del abanico costerò de Sant Llorenf del Munt (Eoceno, cuenca de antepais surpirenaica)
(Sociedad Geológica de España, 1993)The Bartonian-Priabonian Sant Lloreng del Munt fan-delta complex is located at the SE margin of the South-Pyrenean foreland basin. During the deposition of this complex the basin margin was controlled by a series of sinistral ... -
Procesos de sedimentación ligados a flujos gravítacionales en regiones semiáridas. Un ejemplo del SE de España
(Sociedad Geológica de España, 1993)In the studied area the rainfalls ofautum 1973 and 1989 led to the development of gravity flows of mud and/or debris flow type and their characteristic sediments. The analysis of rain fall conditions, processes and deposits ... -
Presencia de mineralogías ricas en Zn como evidencias de la actividad hidrotermal enzonas de cizalla extensionales (Complejo Nevado-Filábride, Béticas)
(Sociedad Geológica de España, 1993)Late Zn-rich assemblages have been found in several lithilogies of the Bédar-Macael unit and upper part of the Calar-Alto unit (Nevado-Filabride Complex). The nowadays brittle contacts between the nevado-filábride and ... -
Presencia de Cloritoide en las pizarras ordovícicas del sinforme de Alcañices (Zamora)
(Sociedad Geológica de España, 1993)In the present work we describe for the first time the presence of chloritoid associated with slates of Llanvirn-Llandellian age (Latedo Formation) o f the southern flank of the Alcahices Synform (Zamora). Usually this ... -
Relaciones entre la diagénesis orgánica y mineral en rocas madre de cuencas lacustres: cuenca terciaria de Ribesalbes
(Sociedad Geológica de España, 1993)Lacustrine carbonate sediments from the Tertiary Basin of Ribesalbes (Castellón, Spain) were studied with the aim of determining the relationships between organic and mineral diagenesis. Petrological and geochemical data ... -
Rasgos generales del relieve en el sector suroriental de la Sierra Almijara (Málaga)
Rodríguez Vidal, Joaquín; Cáceres Puro, Luis Miguel (Sociedad Geológica de España, 1993)
The morphostructural landform o f this Betics coastal sector is conditioned by lithological, structural (Neotectonics) and geomorphologicai features. Tortonian planated relief was faulting during Mio-Pliocene age by a NW-SE ... -
