At first sight it wasnatural to suppose that the Elsworth Rock formed the base of theUpware Corallian, and that the marl and white rubbly limestoneabove it represented the lowest part of the oolite. The ElsworthE,ock comes to the surface a short distance south of the well, whilethe higher beds of oolite and the E,ag in the Southern Quarry risetowards the south, the last-named being lost at the surface some50 yards from the southern end of the quarry. With the slightdip there apparent a considerable thickness of oolite might havecropped out, bringing its basement-bed to the surface in the neigh-bourhood of the field-section and the well. Indeed, but for thewhite limestone and its fauna in this field
