Scully Grove Quarry Wikipedia
The quarry is in the north of the Forest of Dean near Mitcheldean, and is important for its unique features. The basal rock exposed is Crease Limestone which has been replaced as dolomite. It represents a shallow water high energy deposit on a carbonate tamp. There is Whitehead Limestone (Chadian/Arundian) of up to 25 m depth above the Crease Limestone. This shows a peritidal phase of deposition, and includes algal laminates, oncoid beds, thin soils and other features of a significant quality for research purposes. Above this is a small amount of fluvial deposits of the Drybrook Sandstone.
Natural England reported in March 2009 that scrub control was necessary to protect this site of geological interest.Natural England SSSI information on the citation
