El componente bioclástico de playas arenosas de Galicia (NO de España)
(Sociedad Geológica de España, 2004)The bioclastic component of the sandy beaches of the Galician coast is a sensitive parameter which reflects the dynamic features of each beach and also of the whole coastal belt. In the latter case, it is interpreted to ... -
Determinación de la naturaleza de la falla de Cerro Tajo (Macizo peridotítico de Carratraca) mediante termocronología de trazas de fisión
(Sociedad Geológica de España, 2004)Fission-track thermochronology has been applied to assess the nature of the tectonic contact of Cerro Tajo, near Carratraca (Málaga). Zircon fission-track ages support the idea of the extensional nature of the Cerro Tajo ... -
