Lithology and environment
| Primary lithology: | sandy siltstone |
| Secondary lithology: | claystone |
| Includes fossils? | Y |
| Lithology description: the lower 200 m of the section consists of "Interbedded fine-grained sand and silt horizons showing extensive soft-sediment deformation and containing abundant mammal, gastropod and plant macrofossils are interpreted as marshy bog or overbank deposits within a low-gradient fluvial setting" and the middle 250 m of "an upward coarsening succession of lacustrine progradational parasequences" with "profundal lacustrine claystones and deltaic and wave-worked sediments, including evidence of occasional desiccation"; I assume most fossils are from the overbank facies | |
