Field photos and litho-columns showing the lithology, sedimentary structure, and stratal successions of major environmental facies, from which sandstones samples were collected in this study. a Littoral-lakeplain facies showing a high-angle beach accretionary set; b Deltaic facies showing coarsening-upward successions from shale to sandstone; c Fluvial facies showing a fining-upward succession from channel-fill conglomerate to cross-bedded bar sandstone.
