Paragenetic and General Notes

Philipsburgite was identified from Tsumeb on two old, first oxidation zone specimens (Krahn, 2010). At the time of Krahn's description only two specimens were known. On one of these, minute (0.25 mm) sub-spherical aggregates of philipsburgite rest on 'chrysocolla', apparently pseudomorphous after rosasite; on the other, the philipsburgite is associated with quartz and hemimorphite.
