Carboniferous sandstones found in North Worcestershire from Highley to Abberley. Generally greenish to buff, the stone is commonly micaceous and cross-bedded and marked out by the frequent occurrence of small nodules of iron which appear as dark spheres or irregular patches which tend to protrude from the surface. Orange goethite iron staining, particularly on joint surfaces is common.
A couple of local variations occur: Highley Sandstone was quarried in Highley, Shropshire, at Stanley Quarry which in medieval times was owned by Worcester Diocese and forms an important source of stone for the early Cathedral. There are also documentary sources of its use in various bridges along the Severn including Worcester and Bewdley. The Thick Sandstone is the local name given to the formation in the Mamble and Abberley areas as seen, for example, in Abberley Old Church.
