Un Bonaparte en el trono de las Españas y de las Indias. Iconografía de José Napoleón I
2011
En 1808 es proclamado en Madrid rey de las Españas y de las Indias José I, hermano de Napoleón Bonaparte. Su llegada al trono, apoyado por las bayonetas francesas tras la renuncia obligada de los borbones en Bayona, provocará el estallido de la guerra en la península y la desobediencia activa de las colonias americanas. Su reinado, que se prolongará seis años, será una constante guerra de imágenes entre los artistas y apologistas a su servicio, y aquellos que permanecen fieles a Fernando VII y usan la sátira y la caricatura para desprestigiar al monarca impuesto. Pinturas, dibujos y grabados realizados estos años nos muestran el feroz combate visual entre unos y otros, y el fracaso de un re…

1991
CARLO ANTONINI, PERTENECIENTE A LA ESCUELA ROMANA, A CABALLO ENTRE LOS SIGLOS XVIII Y XIX, FUE UN DESTACADO ARQUITECTO, DIBUJANTE Y GRABADOR. EN 1821 PUBLICO UN MANUAL DE TRES VOLUMENES EN EL QUE SE PRETENDIA DAR A CONOCER LAS COLECCIONES DE VASOS ANTIGUOS DE LOS MUSEOS VATICANOS Y OTRAS GALERIAS DE ROMA. EN EL PRIMER VOLUMEN SE OCUPO DE LOS VASOS ANTIGUOS DEL MUSEO PIO-CLEMENTINO. DESCRIBE LAS PIEZAS E INCLUYE GRABADOS DE LAS MISMAS. SUS INSCRIPCIONES Y SU DECORACION PERMITEN ANALIZARLAS ICONOGRAFICAMENTE, PUDIENDO CONCLUIR QUE TODOS PRESENTAN, CON VARIANTES, TEMAS PARECIDOS RELACIONADOS CON LA INMORTALIDAD. (A.B.C./ L.A.G.)
Middle Miocene graben development in Crete and its possible relation to large-scale detachment faults in the southern Aegean
2001
The linkage between the development of south-facing Cretan graben and large-scale detachment faulting in the southern Aegean is unknown. Widespread Serravallian deposits in the Ierapetra graben of Crete supply constraints to Middle Miocene graben development in the southern Aegean. The Ierapetra graben, and by inference the Cretan graben in general, were hitherto believed to have formed as a result of sinistral transpression during N–S shortening. We argue that the formation of the Cretan graben is due to N–S extension. The south-dipping, N–S-extending Kritsa normal fault served as the master fault controlling graben development in the Ierapetra graben. The Kritsa normal fault is either an …
Gravity Anomalies Over The Gongola Arm, Upper Benue Trough, Nigeria
2005
A regional gravity survey of the Gongola Arm of the Benue trough was carried out with the aim of determining structures of interest. The results of the gravity interpretation showed that the area of study is characterized by negative Bouguer anomalies that trend in the NE-SW direction and range in value from -75 to -15 mGal with an average of -42 mGal. A first order polynomial was used to approximate the regional anomalies in the area. The residual gravity anomaly map shows anomalies that range in value from -32 to +20 mGal. 2.5-D modeling of the residual gravity anomalies suggests that the area has a horst and graben structure, with the grabens being as large as 60 km in width and filled w…
Geochronology of the mid-German crystalline rise west of the River Rhine
1996
The mid-German crystalline rise has its westernmost exposures at the western margin of the Rhine graben in the southern Pfalz and the northern Alsace. The outcrops are made up of granitoid rocks and minor volcano-sedimentary sequences. Radiometric ages obtained by U/Pb, Pb/Pb, Sm/Nd and Rb/Sr analyses of the igneous rocks from this area range from ∼433 to ∼325 Ma thus covering a time span from the Silurian to the end of the lower Carboniferous. Because the investigated rocks are — according to their chemical composition — largely related to subduction zone environments, the following three geodynamical scenarios are postulated, always taking subduction of oceanic crust beneath the mid-Germa…
1999
The tholeiitic dolerites that crop out in three diapirs of the SE of the Iberian Chain (Alfarp, Quesa and Lugar Nuevo de Fenollet, Valencia), are the expression of evolved (low Ni, Cr and mg* values) basic magmas, injected into poorly lithified sediments (lutites, marls and gypsum) which represent the Upper Triassic (Keuper facies)-Hettangian boundary, developing sills with reduced thickness. Their mineral and whole-rock geochemical compositions indicate a continental tholeiitic affinity and certain similarities to a MORB composition and, on the other hand, show that the Alfarp dolerites represent the less evolved compositions, whereas the Fenollet dolerites show a significantly greater dif…
Tectonic denudation of a Late Cretaceous-Tertiary collisional belt: Regionally symmetric cooling patterns and their relation to extensional faults in…
2003
Thermochronological data reveal that the Late Cretaceous–Tertiary nappe pile of the Anatolide belt of western Turkey displays a two-stage cooling history. Three crustal segments differing in structure and cooling history have been identified. The Central Menderes metamorphic core complex represents an ‘inner’ axial segment of the Anatolide belt and exposes the lowest structural levels of the nappe pile, whereas the two ‘outer’ submassifs, the Gördes submassif to the north and the Çine submassif to the south, represent higher levels of the nappe pile. A regionally significant phase of cooling in the Late Oligocene and Early Miocene affected the outer two submassifs and the upper structural l…
Resurgent uplift at large calderas and relationship to caldera-forming faults and the magma reservoir: new insights from the Neapolitan Yellow Tuff c…
2021
<p>Resurgence uplift is the rising of the caldera floor, mainly due to pressure or volume changes in the magma reservoir. Identifying resurgence structures and understanding their relationship to the magmatic reservoir is challenging. We investigate the resurgence structures of the Neapolitan Yellow Tuff (NYT) caldera (Italy) by integrating bathymetric data, high-resolution seismic profiles and Differential Synthetic-Aperture Radar Interferometry data. Our results show that the resurgent area is manifested as 1) a central dome constituted by two main blocks bounded by NNE-SSW trending faults, 2) an apical graben developed on top of the most uplifted block, 3) a peripheral zone…
Geodynamic Setting of the Tertiary Hocheifel Volcanism (Germany), Part I: 40Ar/39Ar geochronology
2007
The Eifel volcanism is part of the Cenozoic Central European Volcanic Province and is located close to the Rhine Graben which has been formed by rifting and subsidence since the Eocene. Whereas the Quaternary volcanism of the Eifel appears to be genetically related to mantle plume activity, the cause of the Tertiary volcanism of the Hocheifel volcanic field is less clear. Here, we present geochronological evidence for the geotectonic setting of the Tertiary Eifel volcanism based on 40Ar/39Ar dating of 27 samples from 25 volcanic occurrences. Included are samples from the northern Upper Rhine Graben in order to evaluate a possible relationship between Hocheifel volcanism and Rhine Graben tap…
IST Versus PDE: A Comparative Study
2015
We survey and compare, mainly in the two-dimensional case, various results obtained by IST and PDE techniques for integrable equations. We also comment on what can be predicted from integrable equations on non integrable ones.
