RT Journal Article T1 Características mineralógicas de los sedimentos aluviales holocenos del Barranco Grande (Bardenas Reales de Navarra) T1 Mineralogical characteristics ofHolocene alluvial sediments from the Barranco Grande(Bardenas Reales ofNavarra) A1 Bastida, Joaquín A1 Osácar, María Cinta A1 Muñoz Jiménez, Arsenio A1 Sancho, Carlos AB Mineralogical composition of Holocene alluvial deposits from Bardenas Reales of Navarra is studied and compared with the Miocene mudrock substratum. An Early Holocene muddy-silty unit and another Middle-Upper Holocene sandy unit can be differentiated. Mineralogy semiquantitative results are compatible with weak weathering processes affecting the parent materials under humid conditions prior to Holocene. Besides, differences between alluvial units can be explained in terms of bedrock weathering, sedimentary features, recyclingofsediments and pedogenetic processes YR 2010 FD 2010 LK http://hdl.handle.net/10272/7836 UL http://hdl.handle.net/10272/7836 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
