  Ludlow Shales

  Olive-blue-grey calcareous siltstones, silty mudstones and mudstones. From a building-stone perspective a classification for the Silurian strata based on rock type is most appropriate, not least because the best building stone yielded by this ‘series’ – the Aymestry Limestone – is diachronous and, in the north-west part of Herefordshire, tends to be variable in its […]

  Old Red Sandstone

  The Old Red Sandstone is a large group of rocks of late Silurian and Devonian age.

  Thinly bedded yellow-brown or buff micaceous fine-grained sandstone with interbedded brown-grey siltstone and mudstone. The narrow bedding make the sandstone bands an excellent tilestone and, where the beds are thickest, freestone. In the Mortimer Forest and other areas west of Ludlow, the Downton Castle Sandstone was an important dimension stone for lintels or more important […]
