System:IsometricColour:Olive-green, ...
Hardness:3 - 4
Member of:Roméite Group > Pyrochlore Supergroup
Name:Named for the chemical relation to roméite.
Originally named for August F.W. Partz, who first recognized the mineral as a silver ore.


Originally named partzite.

Generally found as a olive-greenish, fine-grained weathering product of Sb-bearing fahlore.

Note, however, that such weathering products can also be X-ray amorphous.
