The study of the detrital sediments in the Ebro river terraces near Zaragoza has demonstrated that in this area karst is not only an active phenomenon at present but also during the Pleistocene. The Ebro River system had mainly braided features related to a general high water availability and was affected by the development of dolines. The analysis of dolines fillings shows synsedimentary deformation linked to dissolution processes but probably also to tectonics. The preliminary mineralogical study reveals the existence of some diffrences depending on the terrace age and also its own potential in palaeoenvironmental and source area studies.
