Anglesite. (w. Galena and Mimetite-M)

Chemistry: PbSO4

A large crystal of yellow anglesite, attached to a stalactite-like, cylindrical aggregate of galena and mimetite (XRD verified).

This specimen is of particular interest because the mimetite crystals belong to the monoclinic polytype mimetite-M (formerly afforded species status as clinomimetite).  

Mimetite-M from this specimen has been verified by both XRD and Raman analysis.
