Depósitos cuaternarios en el Bajo Ebro: características estratigráficas y deposicíonales

Abstract

In the Bajo Ebro quaternary deposits different lithostratigraphic units are distinguished. Fluvial facies with tabular character: Ford Gravels, Colada Sandstones and Aldover Poligenic Gravels all with siliceous elastics. Alluvial facies with calcareous elastics: the Aldover Monogenic Gravels. These units are attributed to the lower and middle Quaternary. Other units that constitutes fluvial terraces, whith calcareous monogenic elastics are differenciated by their textural character: Xerta Blocks, Llop Gravels and the Assud Sands; these units are attributed to the Thyrrhenian. The fluvial river basin is filled with the Ebro Muds attributed to Holocene
