Tufa sedimentation in changing hydrological conditions : the River Mesa (Spain)
/ Auqué, L. ; Arenas, C. ; Osácar, C. ; Pardo, G. ; et al
The processes controlling tufa deposition along the River Mesa (NE Spain) were studied from April 2003 to September 2009, based on six-monthly monitoring of physical and chemical parameters of the river water and sedimentological characteristics, including deposition rates on tablets. [...]

Modern and late Holocene foraminiferal record of restricted environmental conditions in the Albufeira Lagoon, SW Portugal
/ Alday, M. (Universidade de Lisboa. Centro de Geologia da Universidade de Lisboa e Departamento de Geologia) ; Cearreta, A. (Universidad del País Vasco. Área de Paleontología) ; Freitas, M. C. (Universidade de Lisboa. Centro de Geologia da Universidade de Lisboa e Departamento de Geologia) ; Andrade, C. (Universidade de Lisboa. Centro de Geologia da Universidade de Lisboa e Departamento de Geologia) ; et al
Benthic foraminifera from twenty stations sampled twice were analyzed in order to examine the environmental conditions of the Albufeira coastal lagoon. Foraminiferal assemblages show an increase in the abundance, species diversity and allochthonous content seaward. [...]

An accurate record of volcanic ash fall deposition as characterized by dispersed organic matter in a Lower Permian tonstein bed (Faxinal Coalfield, Paraná Basin, Brazil)
/ Simas, M.W. (Universidade Federal do Rio Grande do Sul (UFRGS). Instituto de Geociências) ; Guerra-Sommer, M. (Universidade Federal do Rio Grande do Sul (UFRGS). Universidade Federal do Rio Grande do Sul (UFRGS)) ; Mendonça, J.G. ; Cazzulo-Klepzig, Filho M. (Universidade Federal do Rio Grande do Sul (UFRGS). Instituto de Geociências) ; et al
For the first time, the dispersed organic matter in the tonstein layer interbedded with a coal seam in the Faxinal Coalfield (Sakmarian, Southern Paraná Basin, Brazil) is characterized. The deposition of clusters of pollen grains was highly influenced by the intense ash fall process that probably occurred during seasonal dehiscence of reproductive structures. [...]

Architectural characterization of a delta-front reservoir analogue combining Ground Penetrating Radar and Electrical Resistivity Tomography: Roda Sandstone (Lower Eocene, Graus-Tremp basin, Spain)
/ Coll, M. (Universitat de Barcelona. Institut de Recerca GEOMODELS – Group of Geodynamics and Basin Analysis) ; López-Blanco, M. (Universitat de Barcelona. Departament d’Estratigrafia, Paleontologia i Geociències Marines) ; Queralt, P. (Universitat de Barcelona. Departament de Geodinàmica i Geofísica) ; Ledo, J. (Universitat de Barcelona. Institut de Recerca GEOMODELS – Group of Geodynamics and Basin Analysis) ; et al
Three-dimensional reconstruction of reservoir analogues can be improved combining data from different geophysical methods. Ground Penetrating Radar (GPR) and Electrical Resistivity Tomography (ERT) data are valuable tools, since they provide subsurface information from internal architecture and facies distribution of sedimentary rock bodies, enabling the upgrading of depositional models and heterogeneity reconstruction.

Mapping of landslide susceptibility of coastal cliffs : the Mont-Roig del Camp case study
/ Montoya-Montei, I. (Universidad Rey Juan Carlos. Departamento de Biología y Geología) ; Rodríguez-Santalla, I. (Universidad Rey Juan Carlos. Departamento de Biología y Geología) ; Sánchez-García, M.J. (Universidad Rey Juan Carlos. Departamento de Biología y Geología) ; Alcántara-Carrió, Javier (Universidad Católica de Valencia. Instituto de Medio Ambiente y Ciencia Marina) ; et al
The weathered and fractured conglomerate cliffs of Mont Roig del Camp constitute a rock fall hazard for the surrounding pocket beaches and, therefore, for the population that frequent them, especially over the summer. [...]
