Terra Nova, 23, 76–84, 2011 Abstract The Triassic Buntsandstein facies in the north‐eastern Iberian Chain (central eastern Spain), previously considered to be fluvial in origin, is shown to contain an evolving erg system. The preserved erg accumulation comprises a succession that represents the transition from a wadi belt via inner erg‐margin to a central‐erg system. This study supports Early Triassic (Olenekian) palaeoclimate models for Western Europe, which predict (extremely) arid conditions for Iberia. The two main easterly and southerly palaeowind directions are in accordance with data from other Triassic dune fields in Europe and corroborate the influence of monsoonal circulation, which affected precipitation in the Variscan Massif to the south and west.

“…Subsidence is considered as the determining factor in the low channel/flood plain ratio. The domain of a high accommodation space and well-developed aggradation systems implies a period with a high subsidence rate (Martinsen et al, 1999;Rygel and Gibling, 2006;López-Gómez et al, 2010). The high contribution of sediments and frequency of f loods in the basin produced channel incision and allowed the onset of progradation of the system.…”

ABSTRACT. The Candeleros Formation is represented by a succession of deposits that represent terminal fans starting to fill a foreland basin (back-arc) during the Albian. The different sub-environments of the terminal fan suggest low gradients during the onset of deposition of the Río Limay Subgroup (Neuquén Group). The terminal fan system is represented by distributary zone (TF-DZ), distributary zone-base zone (TF-DZBZ) and base zone deposits (TF-BZ). Its most notable feature is the presence of bitumen in "pockets" and scattered in the sandstone channel fill and crevasse splays deposit. In this system the feeder zone of the terminal fan system has not been identified, however, the distribution of architectural elements and paleocurrent data allow us to infer that the catchment area of the backbone would have been located to the NNW/NW. Distributary zone deposits are characterized by thick deposits of low sinuosity channel, with a high degree of connectivity and strong vertical aggradation of channel belts. Deposits of distributary zone-base zone are characterized by a higher density of channel deposits/distributary plain, but with belt channel less thick, longer laterally, greater width/thickness ratio and connectivity in the braided deposits. The distal parts of the terminal fan are well represented and vary only in the channelized deposits and mantle/floodplain ratio, which is abruptly reduced towards the flood basin connection. The importance of Candeleros Formation deposits is that they are remnants of accommodation that preserved the original architecture and represent exhumed reservoirs. RESUMEN. Estratigrafía y sedimentología del abanico terminal de la Formación Candeleros (Grupo Neuquén), Cretácico Inferior, Cuenca Neuquina, provincias de Neuquén y Mendoza, Argentina. La Formación Candeleros se encuentra representada por una sucesión de depósitos de megabanicos terminales que representan el inicio del relleno de la cuenca de antepaís (retroarco) durante el Albiano. La identificación de los distintos subambientes del abanico terminal permite inferir bajos gradientes regionales topográficos durante el inicio de la depositación del Subgrupo Río Limay (Grupo Neuquén). El sistema de abanico terminal está representado por depósitos de la zona distributaria (TF-DZ), zona distibutaria-zona base (TF-DZBZ) y zona base (TF-BZ). Su rasgo más destacable es la presencia de bitumen en "bolsones" y de manera dispersa en las areniscas del relleno de canal y en los depósitos de abanicos de desborde. En este sistema no se ha identificado un sistema de alimentación del abanico terminal, sin embargo, la distribución de los elementos arquitecturales y datos de paleocorrientes permiten inferir que el área de captación de la red troncal se habría ubicado al NNW/NW. Los depósitos de la zona distributaria están caracterizados por potentes depósitos de canales de baja sinuosidad, con escasa participación de canales sinuosos, con un alto grado de conexión y fuerte agradación vertical de los cinturones de canal. Los depósitos de la...
