Bedload facies related to sandy hyperpycnal flows. a Clast- to matrix-supported conglomerates, with large clay clasts (facies B1s); b Low angle asymptotic cross bedding with abundant clay clasts (facies B2s); c, d General view (c) and close up (d) of sandy hyperpycnal flow deposits. Note that massive sandstones with clay clasts (facies B3s) transitionally overlie massive sandstones (facies S1) and levee deposits (facies S1L and L), suggesting a gradual flow expansion. Deep-water marine deposits, Lower Cretaceous Achimov Formation, West Siberia, Russia; e Massive sandstones with aligned clay clasts (facies B3s). Pliocene deep-water deposits from Mayaro Formation, Trinidad; f Medium-grained sandstones with aligned clay clasts (facies B3). a, b, f Offshore deposits from the Lower Jurassic Los Molles Formation, Neuquen Basin, Argentina
