Minerals / Baryte, Bryntail. (CWO)

Baryte, Barium sulphate, BaSO4. Bryntail mine, Central Wales Orefield. A solid mass of intergrown bladed crystals. Centrally, the crystals are larger, while those in the lower part are quite small, suggesting that there were different episodes of growth. The Bryntail mine is one of the few mines in central Wales which produced commercial amounts of baryte.
