IGME-CSIC has a highly relevant geological and geophysical database that includes a continuous digital geological cartography at 1:50000; 1:200000 and 1:1000000 scales and a fair amount of geophysical data: gravity, magnetic, well-logs in tiff and LAS format, seismic lines in tiff and SEG-Y format, borehole and petrophysical data, together with other geophysical and geological studies. Since the 2004, an important effort has been done to undertake 3D geological and geophysical modelling ranging from local studies (mineral exploration or CO2 storage sites) to regional geology for a better understanding of the subsurface structure and its geodynamic evolution as a base for other studies on natural hazards or mineral resources. These studies were ¿stand alone¿ and now IGME is designing a new strategy. It includes the available data and models harmonization (stratigraphy sequences, structural interpretations, faults distribution, seismic velocity models, spatial distribution of physical properties such as density and magnetic susceptibility, workflows, methodologies, evaluation of uncertainties, visualization, etc.) to comply with the FAIR (Findable, Accessible, Interoperable and Reusable) data standardization. In this way, the new 3D models will be easily integrated and available from the databases. This strategy includes collaboration with the Bureau de Recherches Géologiques et Minières of France (BRGM) and Laboratório Nacional de Energia e Geologia of Portugal (LNEG) in order to harmonize the Spanish geological data and models with their neighbours across national borders. The first step is being done in the framework of GeoERA projects. Plain-language Summary IGME-CSIC owns a large database that includes a highly valuable geological and geophysical data and geophysical studies containing the interpretation of some of the data of Spain (onshore and offshore) Since 2004 the authors of this work have been working in 3D geological and geophysical modelling that includes local (mineral exploration or CO2 storage sites) and regional studies. The goal is to improve our understanding of the subsurface structures and processes as a base for deepening our knowledge in how the natural hazards occur, how to improve the exploration for mineral resources, etc. These studies were made ad hoc within different projects and now IGME-CSIC is designing a workflow to harmonize these models in order to comply with the FAIR (Findable, Accessible, Interoperable and Reusable) data standardization so the models will be available to being used beyond the initial objectives that generated their creation. This strategy includes collaboration with other European institutions like the Bureau de Recherches Géologiques et Minières of France (BRGM) and Laboratório Nacional de Energia e Geologia of Portugal (LNEG) in order to harmonize the models across national borders. The first step is already being done in the framework of the GeoERA projects.

4 páginas, 4 figuras.-- Trabajo presentado en la 47ª Sesión Científica, Santander, 2009., The Volubilis Neogene basin (Morocco) was part of the South Rif Corridor that connected the Atlantic Ocean with the Mediterranean. This basin recorded the tectonic - sedimentary interactions of a foreland basin subjected to the progressive advance of the Rif mountain range front. Since the Miocene, the displacement of the Prerif to the WSW, caused the detachment of the Mesozoic and Cenozoic cover from the Variscan basement and the compartimentation of Saïss Basin. Simultaneously, the upper Neogene sedimentation continued, developing several types of syntectonic sedimentary structures and Volubilis basin finally becomes a piggy-back basin., Esta investigación ha sido financiada gracias al proyecto CGL 2006.06001, CSD 2006-00041 del MICIN, grupo RNM148 Junta de Andalucía y al proyecto de la AECID: A/018425/08.

11 páginas, 4 figuras., [EN] Gravimetric anomaly maps (Bouguer and residual) of the Guadix-Baza basin (Betic Cordillera, southern Spain) have been accomplished from the acquisition of 3648 new measurements. The residual anomaly map aims to evidence the features of the shallow crustal structures and clearly show the existence of several important depocentres (particularly that of the Baza sector) controlled by NNW-SSE faults in their eastern and western borders, while the northern borders are limited by the Cadiz-Alicante fault zone (s). The sedimentary facies and the thickness of the filling of the basin are consistent with the position of the depocentres: in the Baza area lacustrine facies are more abundant than in the depocentres of Guadix and Freila-Gorafe. The formation of the depocentres is clearly connected with the ENE extension affecting the whole cordillera., [ES] Se han realizado los mapas gravimétricos de anomalías de Bouguer, regional y residual en la cuenca de Guadix-Baza (Cordillera Bética, sur de España) a partir de 3.648 nuevas estaciones de medida. El mapa de de anomalías residuales pretende ayudar a establecer las estructuras de la parte superior de la corteza y muestra claramente la existencia de varios depocentros importantes, en particular el del sector de Baza, controlados por fallas NNO-SSE en sus bordes orientales y occidentales, mientras que la zona de falla de Cádiz-Alicante los limita por el norte. Las facies sedimentarias y el espesor del relleno de la cuenca son congruentes con la posición de los depocentros: en el sector de Baza abundan en mayor proporción las facies lacustres que en los sectores de Guadix y Freila-Gorafe. La existencia de los depocentros está claramente determinada por la extensión ENE que afecta a la Cordillera., Este trabajo se ha realizado a través de la acción especial BTE2001-5230-E (Geometría del basamento de la cuenca de Guadix-Baza. Cordillera Bética) de la SEPCT.DGI, del Ministerio de Ciencia y Tecnología y de los proyectos CGL200401636/BTE, CGL2004- 03333/BTE, CGL2006-06001, CSD2006-00041 y el grupo RNM 217 de la Junta de Andalucía.

11 páginas, 9 figuras., La determinación de la actividad tectónica reciente y actual en la Cordillera del Rif tiene gran interés, ya que está asociada a la actividad de las fallas que determinan la peligrosidad sísmica de la región. El objetivo de este trabajo es describir las características de la actividad tectónica sismogenética en la región de Alhucemas situada en el interior de la Cordillera del Rif, para discutir algunos factores geológicos que no suelen tenerse en cuenta habitualmente en los estudios de peligrosidad sísmica, desarrollados con técnicas aplicables a zonas frontales de cordilleras., Este trabajo ha sido posible gracias a proyectos de colaboración internacional financiados por el MEC, la Agencia Española de Cooperación Internacional y la Agencia Andaluza de Cooperación Internacional.

18 páginas, 12 figuras.-- Editores: G. Moratti y A. Chalouan., The Rif Cordillera is a part of the Alpine orogenic arc in the Western Mediterranean, which was developed by the interaction of the westward motion of the Alboran Domain between the converging Eurasian and African plates. The Prerif Ridges, located along the southwestern front of the Rif, are south-vergent folds that are in places associated with faults affecting Jurassic to Quaternary sedimentary rocks and slope breccias that evidence the deformations that were active over the Neogene-Quaternary period. The different southward or southwestward displacement of each Prerif Ridge is related to the development of frontal and lateral ramps, which may or may not reach the surface. Oblique shortening may be explained by southwestward escape of large tectonic wedges, bounded by large strike-slip faults: the North-Middle Atlas fault which extends northward into the Alboran Sea, the Fez-Tissa-Taïneste fault, the Bou Draa-Sidi Fili fault, the Jebha fault and the Fahies fault. The relative displacement of these tectonic wedges toward the SW may explain the NNE-SSW to ENE-WSW compression observed in the Rif front and in the northern part of its Meseta-Atlas foreland., The research has been financed by collaborative Spanish-Moroccan projects of the Junta de Andalucfa, the AECI and CICYT project BTE2003-01699.

10 páginas, 5 figuras, 1 tabla.-- Trabajo presentado en: The Atlantic Neogene in the XXIth Century: State of The Art., [FR] La bande littorale atlantique de la Meseta marocaine montre dans la région de Casablanca- Mohammedia des dépôts plio-quaternaires qui résultent de plusieurs transgressions marines. Ces formations sont organisées chacune en terrasse marine progradante déposée pendant une période de régression. Ces dépôts marins sont couverts d éolianites qui sont associés aux cordons dunaires plus ou moins parallèles à la côte actuelle. L analyse tectonique de ces dépôts plio-quaternaires révèle que la région d étude, qui était considérée comme étant une zone stable, a enregistré plusieurs déformations cassantes récentes (décrochements, failles normales et diaclases). Il s avère ainsi, que les dépôts plio-quaternaires ont été affectés au moins par deux phases compressives et une phase distensive. Cette tectonique récente peut être liée à la propagation vers l avant-pays de la déformation due à la convergence NW-SE Afrique-Europe et à la progression récente vers le SW du Rif et de son bassin d avant fosse du Saïss-Rharb., [ES] La banda litoral atlántica de la Meseta marroquí septentrional, en la región de Casablanca- Mohammedia, muestra depósitos plio-cuaternarios progradantes como resultado de varias transgresiones marinas. Estos depósitos corresponden a secuencias regresivas y están asociados a terrazas marinas. Las formaciones marinas están recubiertas por depósitos eólicos relacionados con cordones dunares aproximadamente paralelos a la línea de costa. El estudio neotectónico de los depósitos plio-cuaternarios ha permitido precisar la edad de las deformaciones recientes, mostrando que la región estudiada, que había sido considerada como una zona estable, ha registrado varias deformaciones frágiles (fallas normales, desgarres y diaclasas). Estas deformaciones indican que los depósitos plio-cuaternarios han sido afectados al menos por dos fases compresivas y una fase distensiva. La tectónica reciente de la región puede estar ligada a la propagación hacia el antepaís de los esfuerzos asociados a la convergencia NW-SE entre Africa y Europa, y a las deformaciones recientes de vergencia SW del Rif y de la fosa de antepaís de Saïss-Rharb., Ce travail a été financé par la Agencia Española de Cooperación Internacional et la Consejería de Presidencia de la Junta de Andalucía.

Study focus Medina del Campo groundwater body (MCGWB) is a multilayer semiconfined aquifer subject to intensive pumping since the 1970’s, where the current existence of spas where there used to be traditional baths could confirm the existence of deep groundwater flow paths. The old spring of Las Salinas (OSLS) is a saline anomaly in an aquifer with predominance of CaCO3H waters whose occurrence has not yet been formally explained. Long-term geological, geophysical, hydrogeological and hydrochemical records were integrated and complemented with field work to clarify its existence. New hydrological insights for the region Outcomes led to the conclusion that the hydrochemistry of the Olmedo and Palacio de las Salinas salt baths is associated with the existence of a major threshold in the impervious basement of the aquifer, which intercepted deep regional groundwater flow and caused upwelling to the surface under unperturbed conditions. These results allow for the development of a conceptual flow model at the regional scale that explains the changes in natural water chemistry that have been identified in recent decades., This research has received funding from the European Union H2020 Programme under Grant Agreement No. 730497 for the research project NAIAD-NAture Insurance value: Assessment and Demonstration.
