| Lithological Description: |
Red fine-grained, well cemented sandstone and siltstone, either massive or with well developed bedding (cross bedding and parallel lamination). Overlying and underlying units are both red-brown silty mudstone. Unit includes harder silty mudstone lithologies indistinguishable in field. |
| Definition of Lower Boundary: |
Imprecise owing to harder mudstone lithologies; sandstone probably no more than c. 0.6m (proved in a borehole), but the magnitude of the feature suggests the horizon forming it is at least 2m thick. |
| Definition of Upper Boundary: |
See lower boundary. |
| Thickness: |
2 - 3 metres (not exposed). |
| Geographical Limits: |
Not defined. |
| Parent Unit: |
