More model informationFluvial megafan deposits, Oligo-Miocene Ebro Foreland Basin, Aragón. Erosional surfaces are present. These can be overlain either by mudstones or sandstones. The lateral fining in sandstone towards the erosional surfaces, thick mud-infills directly above them, and absence of lag deposits, all suggest little post erosion-modification. The thickest sandstone beds, represent the infill of the deepest and elongate portions of the erosional topography (conduits or channels) which took place during ephemeral flood episodes. Trace fossils (ant-nests) and reddened mudstone laminae in sandstones record dry periods.
