It could be either just based on the photograph and general location. If it is on a waste dump from a copper smelter then slag. There is pillow lava in the area. www.alamy.com/stock-photo/pillow-lava-anglesey.html?sortBy=relevant .

Yes, John, I know that there is pillow lava on the area. We sat and ate our lunch on one of those outcrops in the photos.

closer to 40cm I'd say, but they weren't big.
