“…5: A-center) due to their elliptical forms, with main axis in the direction of the dominant winds and dune rings to the leeward. Moreover, the presence of shallow water tables in some zones of the aeolian system in the DB and in the MP could have conditioned the periods of aeolian deflation and accumulation (aeolian stabilisation with high water tables) as proposed by García-Hidalgo et al (2002) for the eastern zone of the DB.…”

“…6-B, and C) indicate that they have formed by coalescence and piling up of simple dunes at different speeds. One special case of parabolic dunes involves complex parabolic ramps (García-Hidalgo et al, 2002), which are abundant in the north-east (leeward) dunefield of Sanchonuño-Lastras de Cuéllar (Fig. 6-B: north-east).…”

“…Furthermore, in the areas to the windward of the dunefields of the DB, small-sized dome forms have been observed with no defined avalanche faces. According to García-Hidalgo et al (2002), these dome forms could have constituted the initial phases of dune construction which subsequently evolved towards barchan and crescentic forms. In contrast, the star dunes have only been found in the MP, and these are small, short forms (1-3 m) and are similar to hills with more or less rounded crests with irregular arms which radiate from a central point.…”

“…Pérez-González (1982a) also studied the origin of the aeolian deposits and the deflation depressions in the tertiary substratum such as the one in Nava de Rey. Sedimentological interpretations and the dating of the aeolian accumulations in the mid-eastern part of Tierra de Pinares were performed by Temiño et al (1997), Díez-Herrero and Bateman (1998), Díez-Herrero (1999, 2001), Díez-Herrero et al (2002) and García-Hidalgo et al (2002). The works of Desir et al (2003) and Gutiérrez-Elorza et al (2005) on the origin and evolution of playa-lakes in the south-eastern DB show that the wind deflation was responsible for the initial excavation of the Quaternary alluvial cover and the subsequent deepening of the bottom of the playa-lakes.…”

The Utrillas Formation represents clastic wedges that accumulated in relation to continental-coastal areas of Iberian Basin during the worldwide Late Cretaceous sea-level rise. At the Tamajón outcrop the Late Cenomanian Utrillas wedges are composed of four facies associations (FA1 to FA4), which unconformably overlay Triassic deposits. Basal sediments (FA1) are interpreted as high energy, braided fluvial deposits, characterized by coarse-grained (conglomerate-sandstone) facies; which grade upwards to tide-influenced, estuarine sedimentation (sandstones and mudstones with inclined heterolithic stratification, FA2), and then to high-energy, coastal sheet and channelled sandstones with different tidal features (FA3); and finally, to fine-grained (mudstones and minor burrowed sandstones) of an offshore marine associations (FA4). The depositional architecture based in the presence and hierarchy of several ranks of bounding surfaces and the overall upward-fining succession show the long term retrogradational trend of these facies associations. Peculiar sedimentary features of these sediments are 1) the presence of large-scale, single sets of cross beds infilling large erosive channels, which are tidal in origin. 2) The size and length of the cross-bedding defined by couplets of different grain size; here interpreted as originated by flow unsteadiness in relation to changing tides. And 3) an unusual association of ironstones, wrinkle structures and vertebrate tracks with microbial mats and penecontemporaneous iron encrusting allowing track preservation in the sedimentary record.Keywords: continental-coastal facies, large-scale channels, ferruginous crusts, wrinkle marks, vertebrate tracks, Cenomanian. ResumenLa Formación Utrillas está compuesta por una serie de cuñas clásticas que se depositaron en las áreas continentales y costeras de la Cuenca Ibérica durante el ascenso eustático global del Cretácico Superior. En el afloramiento de Tamajón las cuñas del Cenomaniense Superior de la Formación Utrillas están compuestas por 4 asociaciones de facies (FA1 a FA4), que se disponen discordantes sobre materiales triásicos. Los sedimentos basales (FA1) se interpretan como depósitos de sistemas fluviales de tipo braided, de alta energía, caracterizados por facies de grano grueso (conglomerados y areniscas); que pasan hacia techo a facies estuarinas con influencia mareal (areniscas y lutitas con estratificación heterolítica inclinada, FA2), y estas a areniscas tabulares y canalizadas costeras de alta energía que presentan diferentes características mareales (FA3); y, finalmente la sucesión da paso a una asociación marina somera (FA4), de grano fino y baja energía (lutitas con areniscas bioturbadas subordinadas). La arquitectura deposicional se basa en la presencia y jerarquía de varios rangos de superficies erosivas y la tendencia granodecreciente general de la sucesión, que caracteriza la tendencia retrogradacional general de esas asociaciones de facies. Los materiales estudiados presentan una serie de características se...
