Lithology and environment
| Primary lithology: | fine poorly lithified sandstone |
| Includes fossils? | Y |
| Lithology description: "Sand partly consolidated into sandstone is the basis of this deposit through all the low escarpment of the tract which looks northwards on the upper vale of Thames. It is rarely exposed except in road-cuttings, and at the base of the 'coral rag,' where that is quarried for the roads and walls. This occurs on the road to Shotover, at Cowley and Bullingdon, and in the country near Besselsleigh and Marcham. It is in these cases usually a fine sand, with occasional shells" | |
