For this church:
Triassic Mercia mudstone, a hard fine-grained sandstone known as skerry, has been used in the chancel and tower. It was widely used for rubble wall material and is very common in the Trent Valley. It is very hard and not amenable to working, and suffers little erosion.
Triassic Sherwood sandstone being softer can be more easily shaped into blocks and has the characteristic erosion by soft clay clasts found in fluvial sandstones. It has been used in the ashlar work of the building.
