Stratigraphy
| Geological group: | Sherwood Sandstone | Formation: | Otter Sandstone | ||
| Stratigraphic resolution: | formation | ||||
| Stratigraphy comments: "The unit is dated as Anisian on the basis of faunal comparisons and matching with palynologically dated units in the English Midlands... This has since been confirmed by magnetostratigraphy (Hounslow and McIntosh 2003), who found that the lower parts of the Otter Sandstone Formation correspond to the early and mid Anisian, and the upper parts, which contain the majority of the macrofossils correlate with late Anisian and latest Anisian magnetozones on the marine standard." | |||||
Lithology and environment
| Primary lithology: | not reported |
| Environment: | fluvial-lacustrine indet. |
| Geology comments: "The middle and upper parts of the formation are of fluvial origin; sandstones were deposited by ephemeral braided streams flowing from the south and south-west. The comparatively thin mudstones are interpreted as the deposits of temporary lakes on the floodplain. The calcretes indicate subaerial soil and subsurface calcrete formation in semi-arid conditions. The climate was semi-arid, with long periods when river beds dried out, and seasonal or occasional rains leading to violent river action and flash floods." | |
