General Notes
Philipsburgite was identified from Tsumeb on two old, first oxidation zone specimens by Krahn (2010). On one of these, minute (250 µm) sub-spherical aggregates of philipsburgite rest on 'chrysocolla', apparently pseudomorphous after rosasite; on the other, the philipsburgite is associated with quartz and hemimorphite.
Associated Minerals
chrysocolla; hemimorphite; quartz; rosasite
