Notes on the occurrence of Dundasite in Derbyshire and Co. Galway

Published online by Cambridge University Press:  14 March 2018

Extract

An occurrence of the rare mineral dundasite (hydrous carbonate of lead and aluminium) at the Welsh Foxdale mine, Trefriw, Carnarvonshire, was described by Dr. G. T. Prior in 1906. Since then the mineral has been found by the writer at two additional localities in the United Kingdom. Certain specimens collected in 1910 at the well-known Mill Close mine, Wensley, Derbyshire, show a mineral which examination has proved to be dundasite. It occurs here as minute white or yellow spheres, not exceeding ¾ mm. in diameter, the exterior smooth and waxy, the interior radiating and silky.
