VII.—Some Clay Beds by the Ouse
Published online by Cambridge University Press: 01 May 2009
Extract
In the maps of the Geological Survey, Quarter-sheet No. 52, S.W. (Bedford), published in 1863, Upper Lias Clay is shown as bordering the Ouse Valley between Stoke Goldington and Olney, directly overlaid by the Great Oolite, that is to say, the maps indicate an entire absence of the Inferior Oolite (Northampton Sand).
