Abstract
En el valle del río Ebrón (sector central de la Cordillera Ibérica), cerca de
Castielfabib (provincia de Valencia), se diferencian dos unidades tobáceas
encajadas. La antigua, de 77 m de espesor, tiene una edad de 180-100 ka
obtenida mediante Racemización de Aminoácidos, y se correlaciona con los
MIS 6 y 5. Los 25 m superiores de la unidad moderna presentan una edad
de radiocarbono comprendida entre 6 y 2 ka (MIS 1). La sedimentación tiene
lugar en un sistema de barrera y represamiento cuya nucleación parece controlada
por un aumento en el gradiente del perfil del río
Two fluvial tufa units forming a nested fill terrace system were differentiated near Castielfabib (Valencia province) in the River Ebrón valley (central sector of the Iberian Ranges). The older unit (measured ≈ 77 m thick) was correlated to MIS 6 and 5 (180-100 ka) based on Aminoacid Racemization ages. The younger one (minimum measured ≈ 25 m thick) was correlated to MIS 1 (6-2 ka) according to the obtained Radiocarbon dates. Tufa sedimentation was mainly produced in a high gradient, stepped fluvial stretch displaying both barrage-cascade and dammed water areas
