A sill is a tabular sheet intrusion that was intruded between older rocks, often in layered sedimentary rocks. Quartz-dolerite is an intrusive rock, a variety of dolerite that contains small amounts of quartz. These sills are very common in central Scotland and have been widely quarried for roadstone.


Craigton Hill Quarry lies 2 kilometres north-west of Winchburgh, and the nearest public road is in Craigton. Please note that the site cannot be visited as the quarry is located in a private estate.
