General Notes
Parkinsonite from Tsumeb was described by Belendorff (2006) from a single specimen labelled as "cuprite" acquired from an old German collection. The parkinsonite occurs as indistinct, orange-red crystals or rounded, translucent aggregates of crystals (to 1 mm), on cerussite with surface alteration to hydrocerussite. Associated minerals are brucite, calcite (two generations), dolomite, and wulfenite.
Belendorff (2006) proposed the following paragenetic sequence:
cerussite (w. hydrocerussite) >> wulfenite >> dolomite >> parkinsonite >> calcite(rhombohedral) >> brucite >> sepiolite >> calcite(scalenohedral).
