Eocene/Oligocene global disruption and the revolution of Caribbean mangroves / Rull, Valentí (Institut Català de Paleontologia Miquel Crusafont)
In a recent paper, the author demonstrated that, in contrast with the prevailing view of eventual gradual regional differentiation from a hypothetical Cretaceous pantropical mangrove belt around the Tethys Sea, the Caribbean mangroves originated de novo in the Eocene after the evolutionary appearance of the first mangrove-forming tree species known for the region, the ancestor of the extant Pelliciera.

8 p, 784.4 KB Facies de abanicos fluvial en los afloramientos orientales de la formación peratalita / Macias, I. (IB Nicolau Copèrnic (Terrassa, Catalunya)) ; Díaz Molina, Margarita (Universidad Complutense de Madrid) ; Estrada i Aliberas, Ma. Rita (María Rita) (Universitat Autònoma de Barcelona. Departament de Geologia) ; Rampone, G.
La Formación Peraltilla está constituida por una sucesión estratigráfica heterolitica, del Oligoceno inferior. El análisis de facies indica una asociación de ambientes de abanicos fluviales húmedos, formados por canales múltiples de baja sinuosidad, y una tendencia vertical a la progradación de los sistemas fluviales.
The Peraltilla Formation consits of a heterogeneous succession of Early Oligocene age. Facies analysis revealed a characteristic paleoenvironmental association of wet fluvial fan deposits, formed by multiple low sinuosity channels. [...]

14 p, 3.4 MB Stratigraphy and biostratigraphy (charophytes) of the marine-terrestrial transition in the Upper Eocene of the NE Ebro Basin (Catalonia, Spain) / Sanjuan, J. (Universitat de Barcelona. Departament d'Estratigrafia, Paleontologia i Geociències Marines) ; Martín-Closas, Carles (Universitat de Barcelona. Departament d'Estratigrafia, Paleontologia i Geociències Marines) ; Serra-Kiel, Josep (Universitat de Barcelona. Departament d'Estratigrafia, Paleontologia i Geociències Marines) ; Gallardo, H. (Universitat de Barcelona. Departament d'Estratigrafia, Paleontologia i Geociències Marines)
The onset of endorheic sedimentation in the Ebro Basin is a prominent feature of the basin's evolution and has recently been characterized as a rapid event occurring in the Early Priabonian. In the north-eastern part of the basin this event coincides with the deposition of the Artés Formation (Fm. [...]

15 p, 985.8 KB Origin of a restraining bend in an evolving strike-slip system : The Cenozoic As Pontes basin (NW Spain) / Santanach i Prat, Pere F. 1946- (Universitat de Barcelona. Departament de Geodinàmica i Geofísica) ; Ferrús Antón, Beatriz (Universitat de Barcelona. Departament de Geodinàmica i Geofísica) ; Cabrera, Lluís (Universitat de Barcelona. Departament d'Estratigrafia, Paleontologia i Geociències Marines) ; Sáez, A. (Universitat de Barcelona. Departament d'Estratigrafia, Paleontologia i Geociències Marines)
The As Pontes basin (12 km2), NW Iberian Peninsula, is bounded by a double restraining bend of a dextral strike-slip fault, which is related to the western onshore end of the Pyrenean belt. Surface and subsurface data obtained from intensive coal exploration and mining in the basin since the 1960s together with additional structural and stratigraphic sequence analysis allowed us to determine the geometric relationships between tectonic structures and stratigraphic markers.

16 p, 1.1 MB Depositional models of lacustrine evaporites in the SE margin of the Ebro Basin (Paleogene, NE Spain) / Ortí, F. (Universitat de Barcelona. Departament de Geoquímica, Petrologia i Prospecció Geològica) ; Rosell Ortíz, Laura (Universitat de Barcelona. Departament de Geoquímica, Petrologia i Prospecció Geològica) ; Inglès i Urpinell, Montserrat (Universitat de Barcelona. Departament de Geoquímica, Petrologia i Prospecció Geològica) ; Playà i Pous, Elisabet (Universitat de Barcelona. Departament de Geoquímica, Petrologia i Prospecció Geològica)
An important evaporitic sedimentation occurred during the Paleogene (Eocene to lower Oligocene) in the Barberà sector of the southeastern margin of the Tertiary Ebro Basin. This sedimentation took place in shallow lacustrine environments and was controlled by a number of factors: 1) the tectonic structuration of the margin; 2) the high calcium sulphate content in the meteoric waters coming from the marginal reliefs; 3) the semiarid climate; and 4) the development of large alluvial fans along the basin margin, which also conditioned the location of the saline lakes.
