The geology of strata exposed in Roade railway cutting, Northamptonshire : engineering phases Priority 1 and 2

This report describes the geology of the bedrock strata exposed by engineering works between
2005 and 2006 and made available to BGS at the Roade railway cutting, near Northampton. The
strata, totalling about 8.5 m in thickness, belong entirely to the Blisworth Limestone Formation
of the Great Oolite Group, which is of Middle Jurassic age, but the base and top of the formation
are not exposed. The report includes text and graphic sections of the localities examined, a plan
of the cutting showing locations and the distribution of the strata, close-up photographs of the
bedrock exposed, and photographic panoramas of the cutting sides.
