Stratigraphy
Geological group: | Ancholme | Formation: | Oxford Clay | ||
Stratigraphic resolution: | group of beds | ||||
Stratigraphy comments: "In the railway cutting at Kcnnington this sand, fully exposed, is varied with beds and large nodules of sandstone slightly calcareous, while, for a considerable space towards Littlemore, lie widely-interrupted parts of the next rock above, viz. coralline oolite. The oolite lies in separated patches on the same plane, which were probably connected; the intervals between them are occupied by sand which may be supposed to have been left after the decomposition of the oolite. The upper parts of the oolite are absent for a large tract hereabout; and it may be supposed that the large waste of them was caused by long exposure to atmospheric agency in very ancient times (pre-glacial or earlier). This process of surface waste has affected a great part of the area of coralline oolite in Oxfordshire, Berkshire, and Wilts, and seems to explain the patchy and irregular distribution often observable in this rock; though, as far as relates to the purely oolitic and not shelly part of the rock, the original circumstances of deposit must be taken into account." |
Lithology and environment
Primary lithology: | fine,shelly/skeletal poorly lithified sandstone |
Includes fossils? | Y |
Lithology description: "This deposit has been penetrated, by a boring for water at St. Clement's, to a depth of 400 feet. (Add 70 for the higher beds up to the calcareous grit.) The lower parts, which are seen but rarely in the Oxford district, yield Ammonites Duncani; the upper parts, Ammonites vertebralis. Gryphaea dilatata appears in the upper half; and bones of Plesiosaurus occur both in the upper and the lower parts." | |
Environment: | marine indet. |
