However vertical leakage between the two aquifer units may occur via fault systems. The Great Oolite and Inferior Oolite are generally regarded as two distinct aquifers with different water tables separated by the low permeability Fullers Earth Clay. Spring lines are well-developed at the boundary of geological contacts and provide significant baseflow to rivers. Spring discharge in the Cotswolds is considerable and is estimated to exceed artificial abstraction. Being heavily fractured and faulted transmissivity values are high and the resultant combination of low storativity and high transmissivity gives rise to a highly responsive aquifer with large seasonal variations. The control of faulting on aquifer drainage routes is well observed in the Cotswolds with rivers following local fault systems. Disponible tanto para licencias RF como para las licencias RM. Consequently matrix porosities are low and primary aquifer storage is limited.Īquifer storage is further constrained where the saturated thickness of the unconfined limestones in the higher Cotswolds is dissected by heavily incised river valleys and extensive faulting.

A redescription of Megalosaurus hesperis (Dinosauria, Theropoda) from the Inferior Oolite (Bajocian, Middle Jurassic) of Dorset, United Kingdom Benson. The Oolitic limestones are well-cemented and have a low intergranular permeability. The purpose of our study is to identify the stone used in historic buildings while exploring the County and enjoying ourselves immensely The purpose of the website is to add to the sum of knowledge about historic buildings. The fauna consists mainly of belemnites, with occasional small.
The shallow marine depositional environment of the Great and Inferior Oolite Group gives rise to an alternating sequence of limestones and clays the limestone beds themselves being thinly bedded and laterally non-persistent. The principle Jurassic aquifers are the Inferior Oolite and Great Oolite limestones, which overlie the Lias Group and have an outcrop area of approximately 600 km 2 in the Upper Cotswolds.
