| Lithology description: "Light-brown, fine-grained micaceous sandstone which is moderately sorted and relatively coarse bedded. The sandstone fines upward to siltstone and even to mudstone. Pyrite concretions occur sporadically. Scour-and-fill structures are developed at the base of the cyclic units, whereas disiccation cracks and slump structures are more common in the upper portions" | |
