“…Portero et al 1983) and in the Tajo Basin (e.g. Calvo et al 1990), provide an excellent setting for a study of 3D signature of basement deflections in response to fault-bounded uplift and crustal thickening in the Central System. Unfortunately, the geometry of the Duero Basin is not sufficiently constrained to compare 3D flexure modelling results with observations.…”

“…On the other hand the Madrid Basin is hardly affected by Mesozoic extension, and Tertiary continental sediments range in thickness from 1500 m close to the Toledo Mountains and the Sierra de Altomira, up to about 3500 m close to the Central System ( Fig. 14b) (Megias et al 1983;Calvo et al 1990). …”

“…The timing of uplift of the Toledo Mountains is not well constrained but probably of Paleogene age (Racero Baena 1988;Calvo et al 1990). Micromammiferous and palynological data from borehole and outcrop data indicate that uplift of the Sierra de Altomira and Central System, marked by proximal alluvial sedimentation at the margins of the Madrid Basin, started in the Late Oligocene (Racero Baena 1988;Calvo et al 1990). In the Sierra de Altomira, the uplift ceased in the Early Miocene, whereas the Central System shows continuous uplift and sediment supply into the Middle Miocene (Calvo et al 1990).…”

Abstract:The lithospheric driving forces which cause intraplate basin deformation are relatively constant over large areas. Consequently, lateral variations in deformation and stress and strain concentrations seem to be primarily caused by (pre-existing) heterogenities in the rheological signature of the continental lithosphere underlying the sedimentary basins. In this paper, we explore the weak character of upper crustal faults and their control on basin shape for a number of case studies on intraplate Phanerozoic basin settings, using a 2D finite element and a 3D flexure model. Of key importance is the integration of seismic data and field observations with the tectonic modelling, allowing the investigation of deformation processes and their expressions on different scales, operating on different levels of the lithosphere. Finite element models for sub-basin scales, incorporating weak upper crustal faults, predict strong control of these weak zones on local stress distributions and subsequent deformation, in agreement with observed deformation patterns. Slip along upper crustal faults control stress distribution and subsequent faulting in overlying sedimentary rocks. The effect of weak upper crustal fault movements on basin-wide (regional) upper crustal flexure is looked at in two case studies on: (1) extensional tectonics in the Lake Tanganyika Rift Zone (East Africa); and (2) compressional tectonics in the Central System and Tajo Basin (Central Spain). Both settings indicate that basement warpings are controlled by large amounts of slip along so-called weak crustal-scale border faults, which are mostly planar. Adopting border fault displacements in the 3D flexure model, the results indicate low effective elastic thickness (EET) values in a range of 3-7 km for induced basement deflection patterns in accordance with observations. The low EET values most likely reflect a (partly) decoupling of upper crustal and subcrustal deformation, facilitated by the weak lower crust, and in agreement with standard rheological assumptions for Phanerozoic lithosphere. In contrast, the inferred weakness of upper crustal faults relative to surrounding rock is not evident from uniform rheological assumptions. However, observations of reactivations of faults which are not preferably aligned with the stress field, and reactivations of basin deformation on long time-scales are in support of this feature.

“…These sandy fans form part of the alluvial fan systems that supply detrital sediments to the Madrid Basin. The Central System, presumably the source area for the Somosaguas sediments (Fesharaki, 2005), in its western and northwestern zones shows a granite/gneiss composition while its eastern area contains low-grade metamorphic rocks (Calvo, 1989a).…”

“…All these events are consistent with the Alpine Orogeny dynamics that rejuvenated or formed the mountain edges limiting the Tajo Basin (De Vicente et al, 2007). The Madrid Basin is bounded by three main mountain ranges: the Spanish Central System to the north (Somosierra mountains, composed of slates, phyllites and quartzites) and west (Guadarrama Sierra, mainly composed of granodiorites, biotitic granites, gneisses, pegmatites and schists), the Iberian Range to the east (mainly composed of limestones, dolostones, marls and arenites) and the igneous metamorphic series of the Toledo Mountains to the south (Aparicio-Yagüe and García-Cacho, 1984;Calvo, 1989a;Villaseca et al, 1993;Sopeña et al, 2004). During the Upper Palaeogene, the Tajo Basin was subdivided into the Madrid and Loranca Basins by north-south uplift of the Altomira Range.…”

The western area of the Cenozoic Madrid Basin has not been adequately studied. This, combined with the high homogeneity of detrital facies makes the stratigraphic correlation with other areas of the basin rather difficult. Consequently, only a detailed characterization of different study zones can allow subsequent correlation over this area. Over the last years there have been discovered several vertebrate fossil sites in this area that allow the dating of the sediments which host the fossil remains and provide data about palaeoclimatic trends. In this paper we present the results of the light minerals petrographic analysis carried out in one of these sites (Somosaguas paleontological site). Previous palaeontological and isotopic studies in this site indicate a climate event of cooling and rising aridity that has been described globally for the period after the Miocene Climatic Optimum. The petrographic data and indices presented here corroborate this trend towards a more arid climate through the Somosaguas sedimentary succession. Besides we study the grades of alteration of plagioclase grains as a proxy in the evaluation of palaeoclimatic variations. The increase towards the top of the succession of less altered plagioclase grains suggests a decrease in precipitations and thus more aridity. Part of the quartz and K-feldspar grains display several features like embayments and alterations pointing to palaeosoils formation and reworking processes. These characteristics and other observations suggest several sedimentary pulses in a geotectonic setting of "basement uplift" and a mixed lithological provenance for the Somosaguas deposits (granites, gneisses and minor quantities of low-grade metamorphic rocks).Keywords: middle Aragonian, Miocene Climatic Optimum, aridity, palaeosol, plagioclase alteration, sand Resumen La zona occidental de la cuenca de Madrid no ha sido adecuadamente estudiada. Esto, combinado con la alta homogeneidad de facies detríticas dificulta la correlación estratigráfica con otras áreas de la cuenca. En consecuencia, sólo una caracterización detallada de diferentes zonas de estudio puede permitir posteriores trabajos de correlación regional. En los últimos años se han descubierto varios yacimientos de fósiles de vertebrados en esta área que permiten la datación de los sedimentos que albergan estos restos y proporcionan datos paleoclimáti-cos. En este trabajo se presentan los resultados de los análisis composicionales de minerales ligeros realizados en uno de estos yacimientos (yacimiento paleontológico de Somosaguas). Estudios paleontológicos e isotópicos previos en este yacimiento registran un evento climá-tico de enfriamiento y aumento de la aridez que se ha descrito a nivel mundial para el período posterior al Óptimo Climático del Mioceno. Los datos e índices petrográficos presentados en este trabajo corroboran la tendencia hacia un clima más árido a lo largo de la sucesión sedimentaria de Somosaguas. Además, se estudian los grados de alteración de los granos de plagioclasa como prox...
