Borough Green Sand Quarry
|Stone Museum of Geology|
The area of Borough Green is noted for the number of quarries that have been in operation with seven producing limestone (known locally as "Kentish Ragstone") for use in road building and five producing brickearth, clay and sand for use in the construction industry. Borough Green Sandpit is one of the few quarries that is still operating in the area.
As a working quarry it is not open to the public but can nevertheless be viewed from a public footpath that overlooks the site.
The strata here are mainly from the early Cretaceous dating from 126 million years to 100 million years ago and comprise the Folkstone Beds (Sand), Sandgate Beds (Sand) and Gault (Clay). They are then overlaid by Brickearth deposits dating from the Pleistocene. As this area is part of the uplifted Weald Dome Anticline, all of the strata from both the Upper Cretaceous and Tertiary are missing having been eroded away.
The sands quarried here alternate from golden to brown with some ironstone nodules and thin bands with grain sizes varying from coarse to medium to fine. All are of freshwater, rather than marine, origin.
Borough Green & Wrotham Station is on the London Victoria to Ashford and Ramsgate Line. Pay and display parking is available in the centre of Borough Green at Western Road. Buses serving Borough Green are 70, 222, 306, 308 and T13.

Walk north from the centre of Borough Green about a 1/2 mile along the A227 towards Wrotham. Just past the Borough Green village sign on the right hand side of the road you will find a gated public footpath.
Take the path down through the gate and follow the footpath that runs diagonally across the field and you will come to a stile. Go over the stile and follow the path between the trees. After about 200 yards you will come out in the south west corner of another field. Turn right and follow the fence for about 300 yards and you will see the quarry workings on your right hand side.
