Pegmatites

Parascholzite is a secondary mineral produced by alteration of primary phosphates in complex granite pegmatites (HOM).

Localities

At the type locality, the Hagendorf South Pegmatite, Hagendorf, Waidhaus, Neustadt an der Waldnaab District, Upper Palatinate, Bavaria, Germany, parascholzite was discovered on pegmatite specimens, where it occurs as well-developed crystals less than 1.0 mm in size associated with vivianite, phosphophyllite and strengite.
Parascholzite was first identified on a specimen in the Smithsonian collection. Subsequently it appeared that parascholzite also occurs, in some form, at all known scholzite locations (AM 66.843-851). Associated minerals include scholzite, vivianite, phosphophyllite and strengite (HOM).
