Lanterdan Quarry

Lanterdan Quarry

The Lanterdan and West quarries above Vean Hole and Hole Beach at Trebarwith Strand were once some of the biggest in North Cornwall. In Lanterdan quarry there is a tall, distinctive, pinnacle of rock. This was left behind as the slate in the pinnacle was not of a sufficiently good quality; shorter pinnacles were left in West Quarry for the same reason. These chunks of inferior-quality slate were known locally as "scullocks".

The quarry workings never reached the shoreline as there is a fault along the base of the quarry, known as the Trambley Cove Formation. This is made of volcanic lava which was no good to the quarrymen. Lanterdan Quarry is now owned by the National Trust and is a site of geological interest for two reasons. The first is that it contains brachiopod (shellfish) fossils. Second, a rare mineral called monazite is present which contains rare-earth (lanthanide) metals.
