(Sociedad Geológica de España, 2016)The structural characteristics of extensional and strike-slip dextral faults in the central part of the South Pyrenean Central Unit (SPCU), obtained from geological surface data, are here presented. Some of these normal ... -
Caracterización petrológica del sílex de la Formación Calizas de Montmaneu (Sector oriental de la Cuenca del Ebro)
(Sociedad Geológica de España, 2016)Flint from Montmaneu's Limestones Formation of Rupelian age (Oligocene) is being here characterized. The analysis of the compositional texture, mineralogy and geochemical features has revealed this flint is highly pure and ... -
Composición komatiítica de las hornblenditas del Macizo del Montnegre (Sierra Litoral Catalana, NE de la Península Ibérica)
(Sociedad Geológica de España, 2016)Olivine hornblendites represent the most remarkable petrological type from the Montnegre massif. Its ultramafic composition and its close association with a hornblende gabbro intrusion suggest, at first, a cumulative origin ... -
Definición del factor de relajación para la gestión distribuida de recursos geotérmicos someros
(Sociedad Geológica de España, 2016)A new methodology is proposed based on the thermal impact estimation using a groundwater and heat transport model which, combined with the definition of a relaxation factor, allows the approval of new exploitations in an ... -
Depósitos de flujos de sedimentos por densidad en la transición canal-lóbulo submarino: un ejemplo del Tortoniense superior de la Cuenca de Sorbas, SE España
(Sociedad Geológica de España, 2016)The subaqueous sediment density flows (SDF) in Mizala (Sorbas Basin, SE Spain) were deposited during the late Tortonian in a middle submarine fan system, near the channel-lobe transition zone. Channel and lobe deposits ... -
Dinámica fluvial en rifts invertidos a partir del parámetro χ: aplicación a la Cordillera Oriental de Colombia y a otras cordilleras de referencia
(Sociedad Geológica de España, 2016)The aim of this study lies in the extraction of the dynamic state of the drainage network in mountain belts that derive from rift inversion, such as the Eastern Cordillera of Colombia. This study demonstrates that, by ... -
El complejo intrusivo diorítico-gabroico de Susqueda (Macizo del Montseny–Guilleries, Cataluña): unidades litológicas y características petrográficas
(Sociedad Geológica de España, 2016)The intrusive complex of Susqueda constitutes the biggest association of plutonic mafic rocks of the Catalonian Coastal Ranges. It is located in the contact between the large calc-alkaline granitoid intrusions and the ... -
Estudio bioestratigráfico con foraminíferos planctónicos del Santoniense-Campaniense en la sección de Deba-Zumaia (Gipuzkoa): Nueva biozonación con heterohelícidos
(Sociedad Geológica de España, 2016)A biostratigraphic study with Santonian and Campanian planktic foraminifera was carried out in the turbiditic facies of the coastline between Deba and Zumaia (Gipuzkoa), which comprises the Itziar and Aguinaga formations. ... -
