About Cuproroméite
Formula:
Cu2Sb2(O,OH)7
Colour:
Olive-green, yellowish-green, blackish-green, tarnishes black
Hardness:
3 - 4
Specific Gravity:
2.98 - 3.96
Crystal System:
Isometric
Member of:
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.
Partzite discredited in IMA proposal: 16-B. Found to be a very fined grained mixture of a plumboroméite-like oxide phase and a chrysocolla-like amorphous Cu silicate.
