| Lithology description: "massive, medium-grained sandstones and calcareous nodule conglomerates"; latter described as pedogenic | |
| Environment: | "floodplain" |
| Geology comments: "probably deposited either (1) in a low energy fluvial system that was characterized by vast floodplains that were the common sites of sediment accumulation rather than the relatively higher energy fluvial channels; or (2) relatively higher energy river systems with smaller floodplains where mud was not only settling out from suspension, but was transported as sand- and silt sized aggregates in the bed load of the channels" | |
