New lithostratigraphy for the Cantabrian Mountains: A common tectono-stratigraphic evolution for the onset of the Alpine cycle in the W Pyrenean real…
2019
The Pyrenean-Cantabrian Orogen arose through the collision of the Iberian and Eurasian plates, mostly in Cenozoic times. This orogen comprises two main mountain ranges, the Pyrenees to the east, and the Cantabrian Mountains to the west. To date, the early Alpine tectono-sedimentary phases preserved in the Cantabrian Mountains, of Permian and Triassic age, have been considered independently from the same phases in neighbouring basins of SW Europe, and even from the eastern part of the same orogeny (the Pyrenean orogeny). In consequence, the beginning of the Alpine cycle in the Cantabrian Mountains has been interpreted within a specific geodynamic context, far from the general evolutionary ph…
Fusulines of the Hoyo Oscuro section, Ándara massif of Picos de Europa (Cantabrian Zone, N Spain). New constraints about the onset of the Variscan de…
2020
The Hoyo Oscuro section (Andara Massif, southeastern part of Picos de Europa) is a comparatively small exposure of Pennsylvanian syntectonic deposits that shown angular unconformity on the fairly extensive pre-tectonic carbonate platform strata of Pennsylvanian age accumulated in the distalmost realms of the Variscan foreland basin of the Cantabrian Zone. Fusuline-bearing strata from this section yielded species belonging to the genera P seudostaffella, Ozawainella, Fusulinella, Protriticites, Pseudotriticites, Fusulina and Quasifusulinoides ; one of these forms, Protriticites schulzei Villa, is described as a new species from the Cantabrian Mountains. Fusuline assemblages allow us to corre…
SIGNIFICANCE FOR INTERNATIONAL CORRELATION OF THE PERAPERTÚ FORMATION IN NORTHERN PALENCIA, CANTABRIAN MOUNTAINS. TECTONIC/STRATIGRAPHIC CONTEXT AND …
2021
Small ammonoid assemblages are recorded from the Perapertú Formation in northern Palencia. This is a mudstone unit with local platform limestones characterised by carbonate debris flows on the limestone margins. This unit, of Late Bashkirian to Early Moscovian age, participates in a series of southwards verging thrust slicesNorth of a major fault zone which originated as the head (leading edge) of a large thrust sheet with an internal deformation consisting of thrust slices and at least one nappe structure. Opposed vergencies at the head of this major thrust sheet (Carrionas Thrust Front) and the Ruesga Fault which locally modifies its trace, mark the position where the northern branch of t…
Las excavaciones en la zona arqueológica de la Peña Oviedo. Las campañas de 2000 a 2003
2008
Como quedó demostrado en anteriores campañas, las primeras evidencias seguras de un modo de utilización de los recursos que implique la producción de alimentos, ligadas en nuestra opinión, en el caso de la comarca de Liébana, a un pastoreo itinerante, son los asentamientos humanos de las gentes responsables de la construcción de estructuras megalíticas. En las comarcas de Liébana y Polaciones se han excavado varios yacimientos al aire libre asociados a estructuras megalíticas. La excavación de Peña Oviedo (Camaleño) supuso una novedad, en 1991 , al iniciar sondeos en las inmediaciones de esas estructuras megalíticas, con el objetivo de localizar evidencias de la realización de actividades d…
Análisis espacial del Megalitismo cántabro
1995
Se desarrolla un análisis de corte espacial de las evidencias megalíticas conocidas en Cantabria desde un prisma cuantitativo. Las unidades de análisis empleadas son los conjuntos megalíticos, descritos por una serie de variables continuas que definen su variabilidad de modo objetivo. Sobre ellas se aplican técnicas de análisis multivariante y de clasificación automática que permiten explicar la variabilidad métrica, morfológica, de organización y distribución a partir de factores de orden espacial y cronológico. A spatial analysis of the megalithic evidence known in Cantabria is developed from a quantitative prism. The units of analysis used are the megalithic clusters, described by a seri…
