Leach Green Quarry

Exposed Units: Lickey Quartzite

At the disused Leach Green Quarry, the Lickey Quartzite varies from fine grained and white, to coarse, grey and pebbly. It forms massive beds up to about 1m thick, which were lithified and fractured early in the unit’s history. The Lickey Quartzite was exposed at the surface during the Llandovery period of geological time (444-428 million years ago) and represented the floor of a shallow sea at this time. The fractures in the quartzite have been filled up by sandy material deposited in this Llandovery-age sea.
