Abstract
The rare lead zinc arsenate arsendescloizite occurs as pale green crusts associated with calcium-rich mimetite at Sandbed Mine in the Caldbeck Fells, Cumbria. Quantitative chemical analyses show significant substitution of calcium for lead and of copper for zinc. They produce a chemical formula that can be written: (Na0.07,Pb0.71,Ca0.22)(Zn0.73,Cu0.27)[(AsO4)0.94,(PO4)0.04,(VO4)0.01)](OH)0.97, which is remarkably close to the ideal adelite-descloizite group formula. This is the first report of arsendescloizite in the British Isles.
