(2007)This paper describes the stratigraphy and structural setting of a new outcrop of Cretaceous sands and clays located in the center of the exposure of Palaeozoic rocks in the Cantabrian Zone. This isolated outcrop of Cretaceous ... -
Modelo de evolución topográfica en el NO de la Península Ibérica durante la delaminación litosférica al final de la Orogenia Varisca
(2007)Through a simple isostatic balance modelization we attempt an approach to one of the possible lithospheric and topographical scenarios that took place in the aftermath of the Variscan Orogeny. From this point of view, ... -
La Zona Sudportuguesa: propuesta para la división de un bloque continental en dominios
Mantero Romero, Elena María; García Navarro, Encarnación; Alonso Chaves, Francisco Manuel; Martín Parra, L. M.; Matas, J.; Azor, A. (2007)
Three major tectonic domains have been established in the South Portuguese Zone on the basis of cartographic, stratigraphic, lithologic, structural and metamorphic criteria. They are from north to south and from the upper ... -
La serie paleógena de la unidad superior del Gomáride en Talembote (Rif Interno, Marruecos)
(2007)The lower Paleogene stratigraphic successions of the Talembote upper Ghomaride Unit represent an interval of age going from the (middle?) Ilerdian to the early Bartonian, showing a transgressive sequence interrupted by ... -
