Sedimentological studies of ancient fluvial systems commonly do not consider in detail palaeosols floodplain deposits. This is the case upper Paleocene Esplugafreda Formation (Pyrenees, Spain), a 100–340 m thick alluvial succession, which represent more than 80% its thickness. unit closely predates climate crisis Paleocene/Eocene transition, PETM (Paleocene/Eocene Thermal Maximum).
