Volborthite from
Dean Quarry, St Keverne, Cornwall, England, UK


Locality type:Quarry
Classification
Species:Volborthite
Formula:Cu3(V2O7)(OH)2 · 2H2O
Comments:A mineral which is almost certainly volborthite occurs as minute yellow to yellow green spherules (up to about 0.3 mm across) in fractures in the rock. Insufficient material was available for analysis by XRD, but EDS produced a trace which is typical of volborthite. Identification can only be tentative without a confirmatory analysis by XRD, but the data is included in the hope that a detailed examination of further specimens will reveal sufficient material.
Confirmation
Validity:Unconfirmed/Questioned
