21 p, 5.6 MB A new rodent chronology for the late Neogene of Spain / van Dam, Jan (Institut Català de Paleontologia Miquel Crusafont) ; Pierre, Mein (Université Lyon) ; Garcés, Miguel (Universitat de Barcelona. Departament de Dinàmica de la Terra i de l'Oceà) ; van Balen, Ronald T. (Vrije Universiteit Amsterdam. Department of Earth Sciences) ; Furió Bruno, Marc (Institut Català de Paleontologia Miquel Crusafont) ; Alacalà, Luis (Parque de las Ciencias de Andalucía) ; Universitat Autònoma de Barcelona. Departament de Geologia
The number of late Neogene Spanish micromammal-containing continental sections with a correlation to the Geomagnetic Time Scale is steadily growing. Nonetheless, well-calibrated sections with dense micromammal records are still rare, biostratigraphic correlations between basins are not straightforward, and ages of uncalibrated sites are poorly constrained. [...]

20 p, 4.4 MB Geochemistry and Geochronology of the Guajira Eclogites, northern Colombia : evidence of a metamorphosed primitive Cretaceous Caribbean Island-arc / Weber, M. (Universidad Nacional de Colombia) ; Cardona, A. (Smithsonian Tropical Research Institute) ; Valencia, V. (The University of Arizona. Department of Geosciences) ; Altenberger, U. (Potsdam Universität) ; López-Martínez, M. (Centro de Investigación Científica y de Educación Superior de Ensenada (Mèxic). Departamento de Geología) ; Tobón, M. (Universidad Nacional de Colombia) ; Zapata, S. (Universidad Nacional de Colombia) ; Zapata, G. (Universidad Nacional de Colombia) ; Concha, A. E. (Universidad Nacional de Colombia)
The chemical composition of eclogites, found as boulders in a Tertiary conglomerate from the Guajira Peninsula, Colombia suggests that these rocks are mainly metamorphosed basaltic andesites. They are depleted in LILE elements compared to MORB, have a negative Nb-anomaly and flat to enriched REE patterns, suggesting that their protoliths evolved in a subduction related tectonic setting.
