General Notes
Zincobriartite (IMA 2015-094) is the zinc analogue of briartite, first described from Kipushi in the Democratic Republic of Congo (McDonald et al. 2016). Subsequent quantitative and semi-quantitative analyses have indicated that a high proportion of Tsumeb “briartites” are in fact zincobriartite (Frank Keutsch, pers. comm. to M. Southwood 2025). At least semi-quantitative analysis is required for certain identification.
