You will see on occassion Conichalcite like this specimen offered as "barthite". Barthite, however, is an obsolete name as research has shown that barthites are crystallized in discrete phases and not necessarily as a complete solid solution. Further, reports indicate that colorless Austinite is crystallized first and nearly pure Conichalcite is crystallized last. (MR V34, no. 5 pg 62). You would have to check with EDS all specimens to accurately nail down the chemistry and you would have to segregate the zones. We had Cannon check another specimen just like this one and the EDS showed Ca, Zn, Cu. This specimen may also be cuprian Austine.
