Paragenetic and General Notes
Initially described as gallium-rich plumbogummite (Mills et al., 2009). Visually, indistingushable from the un-named gallium analogue of arsenocrandallite. Interestingly a Ge-rich plumbogummite has recently been identified in vugs containing fleischerite and bartelkeite (Joy Desor, private communication to M.Southwood, 2014).
