Description

Area, 5.6 ha. 13.8 ac. Description Rogerley Quarry exhibits a long section in the basal Namurian sandstones, lying just above the great Limestone. The outstanding exposure displays a sequence of sediments now rock formed in a river channel; the quarry face lies at right angles to the channel axis, thus allowing one to view the marked lateral changes which take place across the channel. Structures displayed include a series of large scale, fluvial channel, lateral accretion surfaces essentially the tops of migrating bodies of sand, which are important as the best examples of this kind of structure in the country. This is a key site for sedimentological studies. Other Information This is a new site identified as of national importance in the Geological Conservation Review.
