Massive-bedded oolitic limestone is the characteristic lithology of the Burrington Oolite, which is up to c. 230 m thick in the Wells area, and typically 180–210 m thick over the rest of the Mendip district. Ooliths, of which the limestone is predominantly comprised, are small rounded grains with a concentrically layered cross-section.Texture of Oolite is Clastic or Non-Clastic whereas that of Limestone is Clastic or Non-Clastic.
