Stratigraphy
Lithology and environment
| Primary lithology: | lenticular,bioturbation,medium,coarse,red sandstone |
| Includes fossils? | Y |
| Lithology description: "reddish fluvial sandstones." "stacked, massive, medium-to-coarse-grained sandstone bodies with locally occurring extraformational particles, pebbles and cobbles. Sandstone bodies are typically sheet-shaped, but lenticular bodies occurlocally. Sediments are almost uniformly red in color, but some gray to yellow sandstones also occur. Sandstones are heavily bioturbated with localized occurrences of decimeter-scale, “lumpy” to vertically oriented calcareous concretions that preferentially cement Planolites burrow-fills, and a variety of more complex burrow/dwelling structures of unknown origin." | |
| Environment: | fluvial indet. |
