The aim of this one-day course is to study part descr i pt i on of cl ast composi t i on and of the sedimentary record of the Andean palaeocurrent trends from primary directional Foreland Basin at Potrerillos, a small town located structures (e.g. clast imbrication, cross40 km to the west of the city of Mendoza (Fig. 1). stratification) in order to infer the provenance of the sediments. Based on collected data and The main facies and facies associations and s edi ment ol ogi cal i nt er pret at i ons , t he the geometry of the sedimentary bodies will be participants will finally be able to establish specially analysed by means of detailed relationships between sedimentation and sedimentological logging and mapping of allocyclic controls, such as tectonic activity architectural elements to define the main across the Andean fold and thrust belt and processes of deposition and the sedimentary climate. environments of accumulation. The activity will also focus on the detailed
