EDS confirmed galloplumbogummite spheres (pictures 1-5; picture no. can be seen by mouse overlay on the pictures below) in germanite renierite ore, accompanied by otjisumeite needles (pictures 8-10), unknown bright phase (lead phospate without Cl, picture 9), and stolzite (picture 11).
This sample shows, that only the chemical environment determines whether it is plumbogummite or galloplumbogummite. Several similar looking spheres in a germanite/renierite matrix, where other Ge/Ga minerals are absent, were "only" plumbogummite.
Older material with confirmed galloplumbogummite had a different crystal habit (pictures 6-7) and was accompanied by tsumcorite in flat cracks in germanite ore.
