Summary

The second occurrence of pyrobelonite, MnPb(VO4)(OH), first recorded at långban, Sweden, is reported. It was found with other manganese and iron minerals at the site of an abandoned 19th-century manganese mine at Tŷ Coch near South Cornelly, Mid Glamorgan, Wales. Reflectance values for pyrobelonite from Tŷ Coch, topotype material from Långban, and for two of the minerals associated with pyrobelonite at Tŷ Coch, vanadinite and hausmannite, are given. Electron-probe analyses of pyrobelonite from both localities give results that are in good agreement with its theoretical composition but disagree with the only previous published analysis.
