Stratigraphy
| Geological group: | Chatham | Formation: | Lithofacies Association II | ||
| Stratigraphic resolution: | group of beds | ||||

| Lithology description: "The main quarry exposes about 60 m of red, purple, and grey, fissile to bioturbated massive mudstones interbedded with gray, brown, and red arkosic sandstones. The upper half of the sequence consists of fissile red to gray-green fissile mudstones interbedded with bioturbated massive mudstone and arkosic sandstones arranged in a pattern reminiscent of cyclical lacustrine sequences in other Newark Supergroup basins. At the scale of the outcrop, at least, each fissile mudstone bed is laterally persistent with little lithological change. The lowest fissile mudstone is particularly fine-grained and well laminated and contains a rich invertebrate assemblage. The lower half of the exposed sequence consists of red to purple bioturbated massive mudstone with lenticular arkosic sandstones and several caliche-bearing horizons with occasional articulated to fragmentary reptile skeletons." | |||
| Environment: | fluvial-lacustrine indet. | Tectonic setting: | rift |
| Geology comments: Quarry contains deposits interpreted as lacustrine and fluvial (including channel and crevasse splay). Stegomus and Rutiodon from sandstone levels, all other fossils from lake beds. | |||
