SKU: SEDROK043 Category:

This unusual & rare blue-grey & purple banded mudstone is from below Moughton Fell in Crummackdale, West Yorkshire, known locally as the Moughton Whetstone. It is Silurian in Age but the origins are uncertain. The concentric bands are thought to be Liesegang rings. The mudstone is very hard & fine grained which has made it an ideal honing stone. Traditionally it was used in the Sheffield razor manufacturing industry. Specimens are supplied in various sizes each in a labelled card tray.
