Caption: Limestone from Cults Quarry and Mine, Cupar, Fifeshire.
Description: A specimen of black crystalline limestone from Cults Quarry and Mine four miles south-south-west of Cupar, Fifeshire. The Charlestown Main Limestone crops out, on a hill-slope facing north, from Cults westwards to Coaltown of Burnturk, a distance of about 2 miles. The rocks dip south at 5 degrees. British Geological Survey Petrology Collection sample number MC 7544. The limestone has been quarried along practically the whole outcrop, and mining was resorted to when the overburden became too thick for opencast work. The workings at Cults have now extended nearly 4 miles south from the outcrop, but reserves are still available. On the east the limestone is eventually cut off by a dolerite sill, and westwards also it is seen in close contact with dolerite at Bowden Hill. The limestone in the present Cults working is 12 to 13 feet in overall thickness. It is overlain by a thick bed of shale and rests on a black fireclay 4 feet thick. The top 3 feet. bed of the limestone is left to support the roof in the main levels, but elsewhere the whole thickness of limestone is worked. About 80 per cent of the limestone is extracted, leaving pillars 10 to 12 feet square.
