WebMay 21, 2015 · Absence of lateral-accretion bedding (inclined-heterolithic stratification; Thomas et al., 1987) indicates the existence of stable tidal gullies. In these cases, muddy-intertidal deposits are essentially horizontally bedded and channel-fill sequences are not important volumetrically (cf. Alexander et al., 1991).
