; Draoui, M. (2006)
The Oued Laou alluvial aquifer is one of the most important groundwater bodies in the northwest of Morocco. However, during the last few years this aquifer has been threatened by several pollution sources that have ... -
Bioestratigrafía del Aptiense del macizo del Garraf (NE de la Península Ibérica)
(2006)Six aptian biozones have been recognized by studing the ammonite fauna of Garraf massif: D. weissi, D. deshayesi, D. furcata, E. subnodosocostatum, P. melchioris and A. nolani. The studied ammonoid record is until now ... -
Biogeografía histórica de las clavatoráceas (carófitas fósiles). Estado actual del conocimiento
(2006)The historical biogeography of Clavatoraceae (Mesozoic charophytes) is analysed on the basis of phylogenetic analysis and the data available about its distribution. The most plesiomorphic and oldest representatives of ... -
Características de la red de diques graníticos intruidos en las peridotitas de Ronda (Cordilleras Béticas)
(2006)This work analyses, from the structural point of view, the granite dyke swarm in the R onda area. Structural features of granite dykes from outcrop to microscopic scale show that their intrusion is controlled by ... -
Caracterización de avalanchas de nieve con métodos sismológicos
(2006)Snow avalanches associated risk in mountain areas can be very high. The knowledge of these phenomena is very impor tant in order to mitigate that risk. The avalanche research group at the University of Barcelona has been ... -
Caracterización de la Formación Villar del Arzobispo al sur de Zaragoza (Titónico, Cordillera Ibérica)
(2006)The Villar del Arzobispo Formation (middle Tithonian–lowermost Berriasian) has been recognized for the first time in the two classical outcrops of Villanueva de Huerva and Aguilón (Zaragoza, nor thern Iberian Chain). It ... -
Caracterización geoquímica de los niveles ricos en materia orgánica de los sedimentos turbidíticos del Eoceno, Pirineo Oriental
(2006)The occurrence of or ganic-rich levels in the turbiditic sediments of the Vallfogona Fm (Cadí thrust sheet) in the South-Eastern Pyrenees allowed us the determination of organic matter types, richness and oil potential, and ... -

(2006)A total of 45 species of benthic foraminifers and 8 of ostracods have been studied from the sandy sediment of dunes from Noja (Cantabria, Spain). Dominant assemblages are formed by the species Lobatula lobatula and ... -
Contribución del georadar a la estratigrafia del delta del Río Paraná (Argentina): Primeros resultados
(2006)An important research object when studying river deltas is predicting their internal structure, stratigraphy, lithofacies, depositional history and volume of sand or gravel accumulated. Until recently, prediction was based ... -
Control estructural del Batolito de Tastil (Salta, Argentina) en el desarrollo de cabalgamientos andinos
(2006)This work deals with the structure of the Lower Cambrian batholith of Tastil (Salta, NW Argentina) and its influence on the development of younger Andean structures. Anisotropy of magnetic susceptibility data reveal a ... -
