10 p, 2.2 MB Megalodon, mako shark and planktonic foraminifera from the continental shelf off Portugal and their age / Antunes, Miguel Teles (Academia das Ciências de Lisboa) ; Legoinha, P. (Universidade Nova de Lisboa Departamento de Ciências da Terra) ; Balbino, A. (Universidade de Évora. Departamento de Geociências)
A turbidite specimen collected by a fishing net off the Portuguese coast presents some fossils. A process of condensation is revealed by Late Pliocene and Quaternary typical foraminifera. The matrix is phosphatised and rather iron-rich with small quantities of manganese and zinc and even less copper. [...]

13 p, 1.8 MB Structure of a complex carbonate aquifer by magnetic, gravity and TDEM prospecting in the Jaén area, Southern Spain / Ruiz-Constán, A. (Instituto Geológico y Minero de españa (IGME)) ; Pedrera, A. (Instituto Andaluz de Ciencias de la Tierra) ; Martos-Rosillo, S. (Instituto Geológico y Minero de España) ; Galindo Zaldívar, Jesús (Instituto Andaluz de Ciencias de la Tierra) ; Martín-Montañés, C. (Instituto Geológico y Minero de España) ; González de Aguilar, J.P. (Instituto Geológico y Minero de España)
Knowledge of aquifer geometry is essential for efficient and sustainable groundwater management, particularly in carbonate aquifers due to uncertainties inherent to karstic systems. The geological structure and hydraulic connection of the Los Chotos-Sazadilla-Los Nacimientos and the La Serreta-Gante-Cabeza Montosa carbonate aquifers (S of Jaén; Spain) have been established through structural measurements, geophysical prospecting ―magnetic, gravity and TDEM― and the study of piezometric levels.

6 p, 1.6 MB Evolution of b-values before large earthquakes of mb ≥6.0 in the Andaman region / Prasad, Shweta (ITT Kharagpur (India). Department Geology and Geophysics) ; Singh, Chandrani (ITT Kharagpur (India). Department Geology and Geophysics)
We have considered six earthquakes of mb ≥6. 0, with focal depths within 45 km, in Andaman region during 2000 to 2012 to examine the spatial variations of b-value at epicentre within a one-year period prior to the occurrence of the earthquakes. [...]

18 p, 4.5 MB The Pliocene Mediterranean infilling of the Messinian Erosional Surface : new biostratigraphic data based on calcareous nannofossils (Bajo Segura Basin, SE Spain) / Lancis, C. (Universidad de Alicante. Departamento de Ciencias de la Tierra y del Medio Ambiente) ; Tent Manclús, José Enrique (Universidad de Alicante. Departamento de Ciencias de la Tierra y del Medio Ambiente) ; Flores, J.A. (Universidad de Salamanca. Departamento de Geologia) ; Soria, Jesús (Universidad de Alicante. Departamento de Ciencias de la Tierra y del Medio Ambiente)
The Bajo Segura Basin (eastern Betic Cordillera) is a Mediterranean marginal basin where the Messinian Erosional Surface (MES), formed during the Messinian Salinity Crisis sea-level fall, is well developed. [...]

13 p, 1.9 MB Biochronological data for the Early Pleistocene site of Quibas (SE Spain) inferred from rodent assemblage / Piñero, P. (Universitat Rovira i Virgili. Institut Català de Paleoecologia Humana i Evolució Social) ; Furió, Marc (Institut Català de Paleontologia Miquel Crusafont)
In this paper, the rodent fauna from the Early Pleistocene of Gruta1 (Quibas karstic complex, Murcia, SE Spain) is described. The assemblage includes one arvicoline (Allophaiomys sp. ), two murines (Apodemus ex gr. [...]

12 p, 3.4 MB A new limit for the NW Río de la Plata Craton Border at about 24ºS (Argentina) detected by Magnetotellurics / Faveto, A. (Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET). INGEIS) ; Rocha, V. (Universidad Nacional de Salta, Hidrogeología (Salta, Argentina)) ; Pomposiello, C. (Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET). INGEIS) ; García, R. (Universidad Nacional de Salta, Hidrogeología (Salta, Argentina)) ; Barcelona, H. (Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET). INGEIS)
Old South American structures constitute a puzzle where the Río de la Plata craton is the most important clue in the assembly of SW Gondwana. The present study was performed to improve the knowledge resulting from all the previous magnetotelluric (MT) studies focused particularly on characterizing the western border of the Rio de la Plata Craton.

8 p, 2.5 MB Development of geology in Spain : a case study of a marginal science / Santanach i Prat, Pere F. (Universitat de Barcelona. Departament de Geodinàmica i Geofísica)
Geology in Spain developed outside the mainstream of major geological ideas. Geology was introduced intothe country when it had already grown mature. The history of geology in Spain is series of initiatives aimedat aligning the country with the innovative currents taking place in the rest of Europe. [...]
