Fig. 8From: Spatial and temporal variations in depositional systems in the Kazusa Group: insights into the origins of deep-water massive sandstones in a Pleistocene forearc basin on the Boso Peninsula, JapanDownflow changes in thickness, lithofacies types, and grain sizes of a sandstone bed developed just above the U2 tephra key bed in the Umegase Formation. The inset map shows the locations of the measured sections. Black filled circles in grain-size diagrams denote volume percentages of muddy grains less than 20 μm.
