12 p, 3.1 MB Multidetachment analogue models of fold reactivation in transpression : the NW Persian Gulf / Soleimany, B. (National Iranian Oil Company) ; Nalpas, T. (Géosciences Rennes (França)) ; Sàbat, F. (Universitat de Barcelona. Departament de Geodinàmica i Geofísica)
Two deformation events have been documented in the NW Persian Gulf during the Late Cretaceous and the Late Cenozoic. The most distinctive feature in this part of the Persian Gulf is the reactivation of the Late Cretaceous NNE-SSW Arabian trending folds by NE-SW shortening during the Late Cenozoic Zagros orogeny.

Departamento de Geodinámica) ; Consejo Superior de Investigaciones Científicas (Espanya). Instituto Andaluz de Ciencias de la Tierra
The distribution pattern of diagenetic conditions to very low-grade metamorphism in the eastern Rif has been determined based on a study of clay-mineral assemblages and illite crystallinity of Mesozoic metapelites. [...]

16 p, 1.8 MB Ultrapotassic volcanic centres as potential paleogeographic indicators : the Mediterranean Tortonian 'salinity crisis', southern Spain / Cambeses, A. (Universidad de Granada. Departmento de Mineralogía y Petrología) ; Scarrow, J. H. (Universidad de Granada. Departmento de Mineralogía y Petrología)
Dated peperites associated with ultrapotassic volcanic centres of the Neogene Volcanic Province of southeast Spain are of particular interest within the complex tectonomagmatic context of the Western Mediterranean because they show clear volcano-sedimentary interactions making them a valuable tool for correlating between Miocene sedimentary basins in the region.

11 p, 1.2 MB Lithospheric magnetic mapping of the northern Caribbean region / Catalán, M. (Real Instituto y Observatorio de la Armada) ; Martín-Dávila, J. (Real Instituto y Observatorio de la Armada)
A more complete crustal perspective of the northernmost part of the Venezuela Basin is provided by data from an international public database processed with new geomagnetic models (CM4) together with data from aeromagnetic surveys and from a recent marine cruise in areas offshore Puerto Rico and the Dominican Republic.

10 p, 1.4 MB Palaeoecology of the Cenomanian amber forest of Sarthe (western France) / Girard, V. (Université Montpellier 2. Centre de Bio-Archéologie et d'Ecologie) ; Néraudeau, D. (Université de Rennes 1. Géosciences Rennes) ; Breton, G. (Université de Rennes 1. Géosciences Rennes) ; Morel, N. (Musée Vert, Muséum d'Histoire Naturelle du Mans)
Cretaceous ambers have been discovered in France since the beginning of the 18th century. The best known are those from south-western France which are Late Albian-Early Cenomanian in age, but there are other important amber deposits in other regions. [...]

28 p, 6.7 MB Cenozoic contractional tectonics in the Fuegian Andes, southernmost South America : a model for the transference of orogenic shortening to the foreland / Torres Carbonell, P.J. (Consejo Nacional de Investigaciones Científicas y Técnicas (Argentina). Centro Austral de Investigaciones Científicas) ; Dimieri, L. V. (Universidad Nacional del Sur. Departamento de Geología)
The Fuegian thrust-fold belt has been subjected to significant shortening during the Cenozoic. Although contemporaneous shortening and uplift was also recognized in the Fuegian Andes central belt (hinterland), previous studies stated that most of that deformation developed out-of-sequence with the thrust-fold belt and hence did not contribute to its shortening.

14 p, 777.0 KB Physico-chemical analysis of Albian (Lower Cretaceous) amber from San Just (Spain) : implications for palaeoenvironmental and palaeoecological studies / Dal Cors, J. (Università degli Studi di Padova. Dipartimento di Geoscienze) ; Roghi, G. (Istituto di Geoscienze e Georisorse (IGG-CNR)) ; Ragazzi, E. (Università degli Studi di Padova. Dipartimento di Scienze del Farmaco) ; Angelini, I. (Università degli Studi di Padova. Dipartimento di Geoscienze) ; Giaretta, A. (Istituto di Geoscienze e Georisorse (IGG-CNR)) ; Soriano, C. (European Synchrotron Radiation Facilities (ESRF)) ; Delclòs, X. (Universitat de Barcelona. Department d'Estratigrafia, Paleontologia i Geociències Marines) ; Jenkyns, H.C. (University of Oxford. Department of Earth Sciences)
Amber from a Lower Cretaceous outcrop at San Just, located in the Eastern Iberian Peninsula (Escucha Formation, Maestrat Basin), was investigated to evaluate its physico-chemical properties. Thermogravimetric (TG) and Differential Thermogravimetric (DTG) analyses, infra-red spectroscopy, elemental and C-isotope analyses were performed. [...]
