(Sociedad Geológica de España, 2005)The analysis of the natural answers of the principal springs (Río Jorox, Fuente Quebrada and Carratraca) of the Prieta-Bonela-Alcaparaín aquifer system has allowed to determine the hydrogeological characteristics and the ... -
Caracterización Geomorfológica de la Ciudad de Valera (Estado Trujillo, Venezuela)
(Sociedad Geológica de España, 2005)Since 1990, several problems of instability have been known in the terrace of Valera caused in the border of the slope by the downward movement of itself. Example of this is what has happened with the structures in the ... -
Circulación de fluidos en fracturas en el miembro superior de la Fm. Armàncies (Eoceno, Pirineo oriental)
(Sociedad Geológica de España, 2005)The presence of oil shows associated with fractures provides a significant opportunity to unravel the type, origin and evolution of fluids involved in fractures cementation and their relationship to oil migration. Two stages ... -
Definición de zonas sismogenéticas en base al gradiente geotérmico, resistencia y profundidad del límite frágil-dúctil en la corteza superior. Aplicación metodológica para el cálculo de la peligrosidad sísmica en el Sureste de España
(Sociedad Geológica de España, 2005)In this work we present a methodological approach to define seismogenic zones for seismic hazard analysis based on the relationships which can be drawn from the geothermal gradient, total strength of the upper crust and ... -
Descripción de las facies presentes en el relleno holoceno del sector externo de la Bahía de Cádiz
(Sociedad Geológica de España, 2005)The Holocene sedimentary evolution in the continental margin of Cadiz Gulf is affected by different factors, which control the nature and distribution of the deposits. The physiography of coast and sea bottom linked to ... -
Determinación experimental del contenido en CO2 del suelo sobre una cavidad kárstica en clima mediterráneo (Cueva de Nerja, Málaga)
(Sociedad Geológica de España, 2005)The CO2 content and the temperature of the air have been measured within the scarce soil (although with relatively high organic matter concentration) which partially covers the carbonate outcrops over the Nerja Cave ... -
Distribución espacial y zonificación tectónica de los morfolineamientos en la Isla Decepción (Shetland del Sur, Antártida)
(Sociedad Geológica de España, 2005)Deception Island (South Shetland Islands, Antarctica) is one of the most active volcanoes in Antarctica, having recently erupted in 1967,1969 and 1970. It is also seismically very active, as 1992 seismic crisis was noted. ... -
Efectos tectónicos recientes en el Campo de Calatrava deducidos de los datos paleomagnéticos del volcanismo neógeno
(Sociedad Geológica de España, 2005)The Campo de Calatrava region shows some effects of the recent tectonics related to origin of the Betic orogen. Some of the effect recognizable at Campo de Calatrava was: vertical blocks movements leading to depressions ... -
Estimación del terremoto máximo posible y su intervalo de recurrencia en la Falla de Carrascoy (Murcia) para su implementación en el cálculo de la peligrosidad sísmica de la región
(Sociedad Geológica de España, 2005)Seismogenic source characterization in seismic hazard analysis of moderate activity areas is usually solely based on the seismogenic zone concept and the available historical records. However, the location of future big ... -
