Abstract
Arsenogoyazite occurs as opaque white pseudo-cubic crystals in cavities in quartz veinstone collected from the dumps at Wheal Cock, St Just, Cornwall. The crystals show complex chemical substitutions. They are fluoride, sulphate and phosphate-rich and contain significant calcium and barium. This is the first report of arsenogoyazite in the British Isles.
