HISTORIC SCOTLAND TAN 12 QUARRIES OF SCOTLAND
(iv) Corsehill Sandstone
Early Triassic rocks crop out in the Annan Basin in the Annan and Gretna district and form part of the sequence of strata extending southwards into the Carlisle Basin and Vale of Eden. Around Annan they are represented by unfossiliferous water-laid, finegrained, sandstones. Stone from this sequence has been worked at Corsehill Quany (Figures 2 and 3) for many
Corsehill Quarry, Annan (C3609), 1937 A view of the working face of the quany illustrates the very different characteristics of the strata compared with the Permian desert sandstones. Beds are generally thinner, but are laterally continuous. Internal cross-bedding within some beds is discernable but is much smaller in scale and less prominent than in the desert sandstones. Drill holes are clearly seen. Tool marks on some beds may indicate that the stone was squared up while still in the face. The overburden of till is up to 5 m thick.

years and currently the Dunhouse Quany Company Ltd continues to supply stone (Appendix 2) for both the home and overseas market. The depth of the quarry in the early 1900s was of the order of 30 m. Being fineto very fine-grained and capable of carrying a sharp arris the stone has traditionally been used for all kinds of inside and ornamental work and carving, and is noted for its use not only as a construction stone but also for monuments, panels, quoins and plinths.
