RT Journal Article T1 Desarrollo de estructuras agradacionales generadas por oleaje en lagos someros carbonatados. Un ejemplo del Oligoceno superior de la Cuenca del Ebro T1 Climbing sructures generated by surges in carbonated shallow lakes. An example from the upper Oligocene of the Ebro Basin A1 Luzón, Aránzazu A1 Soria, Ana Rosa AB During the upper Oligocene a carbonated shallow lacustrine system developed in the central sector of the Ebro Basin. The lacustrine system was closely related to alluvial systems spreading from the margins to the centre of the basin. The periods with important surge dynamics in the lacustrine area caused the reworking of the materials deposited in the lake and the creation of sand bars basically formed by climbing structures of different types and scales PB Sociedad Geológica de España YR 1997 FD 1997 LK http://hdl.handle.net/10272/10281 UL http://hdl.handle.net/10272/10281 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
