Mineralpedia Details for Partzite

Currently called cuproroméite on mindat.org which claims it is “probably cuproroméite” but the actual type material has not been analyzed by electron-microprobe for its chemical and structural properties, Partzite is named for August F.W. Partz who was the first to discover Partzite as a silver ore. Partzite occurs as a product of the alteration of antimony-rich sulfide deposits and can be found in the United States, Germany, Austria, and Australia, among just a few others.
