About Oathill Cotswold Limestone Quarry
Oathill Quarry, located just outside the picturesque village of Temple Guiting in Gloucestershire, is considered by many to be the original Cotswold Limestone Quarry. Renown for its high quality masonry block stone, for several centuries the quarry was known as Guiting Quarry but in recent years the quarry has become known as Oathill Quarry.
Acquired by the Johnston Quarry Group in the summer of 2008, the 60 acre freehold property now has over 1.5 million tonnes of consented reserved and is once again producing the finest quality Cotswold block, walling stone, aggregates and agricultural lime.
The quarry is actually split into two by a small valley through the bottom of the quarry. The historic geological feature may well contribute to the distinct coloration of the block on either side - on the eastern side of the quarry are the progressively worked Cotswold Cream block beds and on the western side is the unique Guiting Gold block beds. As the quarrying process develops under the increase investment made by Johnston Quarry Group block yields and availability are expected to increase substantially.
The limestone strata exposed and underlying the quarry site belongs to the Inferior Oolite Group of the Middle Jurrasic. The sequence lies entirely within the Birdlip formation and the principle building stones (White, Yellow and Gold Guiting) lie within the Cleeve Coud Member of that formation which is approximately 38m thick.
