“…The massive sand of the Sm lithofacies implies a rapid deposition from a highly sediment-saturated flow (Mulder and Alexander, 2001;Baas et al, 2016). The association of depositional processes points to an alternation of channelized traction current and surge-type flows, unconfined subaerial gravity flows and overbank calm deposition of mud, implying a depositional environment of a proximal braided river with a small catchment prone to significant yearly discharge variability (Miall, 2006;Fielding et al, 2018;Paseban et al, 2018) (Table 2). Lithofacies codes are explained in Table 1.…”
