Application of specific extraction chromatographic methods to the Rb-Sr, Sm-Nd isotope study of geological samples: The Hombreiro-Santa Eulalia Granite (Lugo, NW Spain)
(Sociedad Geológica de España, 1996)The analytical application to geological samples of three new chromatographic resins, TRU-Spec ®, Sr-Spec ® and LN-Spec ®) has been investigated. Seven samples of the Hombreiro massif (Lugo, NW Spain) have been studied, ... -
Caracterización geoquímica de las peridotitas del macizo de Sierra de Aguas (Málaga)
(Sociedad Geológica de España, 2004)In order to constraint geochemical differences related to the petrogenesis ofthe Ronda peridotites, major and trace elements combined with chondrite normalized REE patterns of the Sierra de Aguas Massif peridotites, near ... -
Composición isotópica del Pb en galenas de la región de la Falla de Azuaga. Aportaciones al modelo plumbotectónico de la Zona de Ossa-Morena
(2007)New Pb isotopic analyses have been obtained on twenty samples of galena from the Azuaga area. In spite of the overall homogeneity, the results for samples to the North of the Azuaga Fault are perceptible different from ... -
Estudio de la composición isotópica del Pb en galenas del distrito minero de Linares-La Carolina (Jaén, España)
(Sociedad Geológica de España, 2003)New lead Isotope results for twenty-four galenas of the Linares-La Carolina mining district (Jaén, Spain) are reported. While two.mineralization types, one near Linares (where filons with low Ag content crosscut the Linares ... -
Geocronologia del plutón de Campanario-La Haba (Badajoz) a partir del análisis de isótopos de Pb en circones y U-Th-Pbtota| en monacitas
(Sociedad Geológica de España, 2003)The Campanario-La Haba pluton is located to the north of the Los Pedroches batholith in the southern part of the Central-lberian Zone. The age of the emplacement had been established between 304 and 314 Ma using K-Ar and ... -
Nd isotopic heterogeneity in Iate-Hercynian granitic plutons from Central Spain
(Sociedad Geológica de España, 1997)Some Hercynian granitic plutons from Central Spain show variation in initial Nd isotopic ratios defining different trends with increasing silica content. There is a decoupling between the Sr and Nd isotopic systems as these ... -
Nuevos datos petrológicos, geocronologia (Rb-Sr) y geoquímica isotópica (Sr, Nd) del plutón de Ventosilla (Sierra de Guadarrama, Sistema Central Español)
(Sociedad Geológica de España, 1997)Whole rock Rb-Sr ¡sotopic analyses on granites from Ventosilla pluton yield an age of 346 ± 63 Ma, and intercept at 0.708688 ± 0.00094. This age increases the time-span of the Hercynian plutonism in the area up to 70 Ma. ... -
Variaciones en la composición isotópica del Pb en galenas del área de Los Pedroches: diferencias entre los yacimientos de El Zumajo y Linares-La Carolina
(Sociedad Geológica de España, 2002)We report the results of Pb isotope analyses on representative galena samples from the El Zumajo quartz-rich dyke. This is a late intrusion within the Cardeha-Virgen de La Cabeza granite of the Los Pedroches Hercynian ...
