Gneissose foliation in Chase End Quarry
Geological Overview
The quarry lies within a fault-bounded inlier (an area of older rocks surrounded by younger rocks) composed of the rocks of the Malverns Complex. This inlier forms the southernmost extent of the Malvern Hills and, as such, the quarry is the most southerly exposure of the Malverns Complex. The rocks in the quarry are metamorphic rocks of the Malverns Complex. The rocks were originally diorites; medium to coarse grained intrusive igneous rocks, containing plagioclase, amphibole or biotite, estimated to be around 680 – 670 million years old.
