14 p, 9.8 MB Hydrological conceptual model characterisation of an abandoned mine site in semiarid climate : the Sierra de Cartagena-La Unión (SE Spain) / Robles-Arenas, Virginia María (Universidad de Granada. Instituto del Agua) ; Candela Lledó, Lucila (Universitat Politècnica de Catalunya)
A comprehensive study at Sierra de Cartagena-La Unión (SE Spain) abandoned mine site was carried out to characterise the regime and water quality of the groundwater system after the mine closure. The system consists of five geologic fractured blocks belonging to the Alpujarride and Nevado-Filabride complexes. [...]

28 p, 13.2 MB Lower Aptian ammonite biostratigraphy in the Maestrat Basin (Eastern Iberian Chain, Eastern Spain). A Tethyan transgressive record enhanced by synrift subsidence / Moreno Bedmar, Josep Anton (Universitat de Barcelona. Departament de Geoquímica, Petrologia i Prospecció Geològica) ; Company, M.

The present paper analyses the stratigraphic distribution of ammonites collected in the Lower Aptian sediments of the Maestrat Basin (E Spain). The faunal successions obtained from the systematic sampling of ten selected sections located in several sub basins led us to identify four biostratigraphic units (from base to top: Deshayesites oglanlensis, Deshayesites forbesi, Deshayesites deshayesi and Dufrenoyia furcata Zones) that are directly correlatable with the current Mediterranean standard zonation.

23 p, 18.0 MB Earliest Pragian (Early Devonian) corals and stromatoporoids from reefal settings in the Cantabrian Zone (N Spain) / Fernández-Martínez, E. (University of Léon. Faculty of Biology and Environmental Sciences) ; Fernández, L.P. (University of Oviedo. Department of Geology) ; Méndez-Bedia, I. (University of Oviedo. Department of Geology) ; Soto, F. (University of Oviedo. Department of Geology) ; Mistiaen, B. (Université Catholique de Lille. Laboratoire de Paléontologie stratigraphique)
The oldest reefal episode in the Cantabrian Zone (earliest Pragian) consists of small biostromal patch reefs, mainly built by corals and stromatoporoids, and developed on a storm-dominated ramp. Four outcrops provide the stratigraphic framework in which these reef facies developed, and these permitted an interpretation of their depositional setting in terms of a relatively distal or protected shelf.

16 p, 11.6 MB Organic-Rich facies in the Sinemurian and Pliensbachian of the Lusitanian Basin, Portugal : Total organic carbon distribution and relation to transgressive-regressive facies cycles / Duarte, L.V. (Universidade de Coimbra. Departamento de Ciências da Terra and IMAR-CMA) ; Silva, R.L. (Universidade de Coimbra. Departamento de Ciências da Terra and IMAR-CMA) ; Oliveira, L.C.V. (PETROBRAS/RH/UP/ECTEP/PETROBRAS/RH/UP/ECTEP) ; Comas-Rengifo, M.J. (Departamento-UEI de Paleontología, UCM-CSIC) ; Silva, F. (Galp Energia)
The upper Sinemurian to Pliensbachian series of the Lusitanian Basin (Portugal) correspond to marly limestone sediments rich in benthic and nektonic macrofauna. This sedimentary record includes several intervals of organicrich facies, which are particularly well developed in the western sectors of the basin. [...]
