Fig. 12From: Sedimentary architecture of shallow-water fan-delta front in a lacustrine basin: Sangyuan section of Lower Cretaceous Xiguayuan Formation, Luanping Basin, northeast ChinaVertical grain-size trend of mouth bar accretions varies with grain size. Accretions involving coarse-grained sediments (median grain size is > 1000 μm) display fining-upward trends, whereas those with fine-grained sediments (< 1000 μm) are characterized by inverse gradingBack to article page
