Análisis mineralógico de las escorias de forja del yacimiento romano de Forua (Bizkaia)
(Sociedad Geológica de España, 2016)The archaeological site of Forua (Bizkaia) corresponds to an iron production centre of the Roman period (1st–3rd centuries AD). The distribution of the workshops joint to the type of slags indicates that correspond to a ... -
Cartografía y petrografía de un sector del sistema filoniano N120-130E asociado al batolito de Los Pedroches (Córdoba, Zona Centro-Ibérica)
(Sociedad Geológica de España, 2001)The Los Pedroches batholith (Iberian Massif, SW Spain) is composed by a large granodioritic intrusion and smaller monzogranitic plutons. This batholith is cross cut by a dyke complex of lamprophyres, trachyandesites, ... -
Composición isotópica de gasterópodos en secuencias aluviales holocenas de Bardenas Reales (Navarra): implicaciones paleoambientales
(2009)Stable isotope composition of five species of gastropods from the Late Holocene alluvial record was studied in Bardenas Reales Natural Park (Navarre province) in order to deduce palaeoenvironmental information. Snails ... -
Estudio morfométrico comparativo de la escápula y húmero de ciervo (Cervus elaphus) y reno (Rangifer tarandus) del Pleistoceno Superior
(2009)The aim of this paper is to offer a comparative morphometric study of scapula and humerus between red deer (Cervus elaphus) and reindeer (Rangifer tarandus). Both species show a similar morphology but with small differences ... -
Evaluación de la diagénesis en huesos arqueológicos y caracterización de la relación 87Sr/86Sr local en la evaluación de migraciones humanas
(2013)Los estudios isotópicos de Sr se utilizan para establecer pautas de migración humana. La relación 87Sr/86Sr en restos humanos viene determinada por el entorno geológico donde vivió la persona. Sin embargo, esta ... -
Evaluación del grado de diagénesis en huesos fósiles mediante espectroscopía de infrarrojos
(Universidad de Huelva, 2010)In this paper the fossil bone conservation and the diagenetic changes are studied by infrared spectroscopy (FTIR). Several parameters that describe crystallographic and chemical composition of the bone are used. The ... -
Gasterópodos del registro aluvial holoceno en Bardenas Reales de Navarra
(2008)The gastropod content of the Late Holocene alluvial morphosedimentary record was studied in the Bardenas Reales Natural Park (Navarra province). Seven species of micromoluscs was identified: Lymnaea truncatula (Müller, ... -
Inocerámidos y sedimento carbonatado (Maastrichtiense inferior, Arco Vasco): Comportamiento de la relación 87Sr/86Sr durante la diagénesis. (Parte I)
(Sociedad Geológica de España, 2001)Strontium isotopic analysis have been carried out on whole rock and inoceramid shell samples from deep-sea carbonate sediments at Sopelana and Bidart sections (Basque Arc). They were compared with oxygen isotope values ... -
Los diques traquiandesíticos asociados al plutón granodiorítico de los Pedroches (batolito de los Pedroches, España)
(Sociedad Geológica de España, 1996)The Los Pedroches batholith is cross cut by an important dyke complex, particularly well developed in the central sector. Dykes are mainly trachyandesite, rhyolite, whole emplacement history of the Los Pedroches batholith ... -
Nuevos datos geocronologicos Rb - Sr del pluton de Campanario - La Haba (batolito de Los Pedroches, Extremadura)
(Sociedad Geológica de España, 2003)A Rb-Sr whole-rock array corresponding to a circa age of304 ± 6 Ma has been obtained for the peraluminous granite of Campanario - La Haba pluton. The Sr initial ratio of 0.70619 ± 0.00034 of this pluton is less radiogenic ...
