Paragenetic and General Notes
Segnitite occurs as brown irridescent crystals, to 5 mm, and is visually indistinguishable from beudantite; analysis is therefore required for verification.
It was first identified at Tsumeb on material from the collection of John Innes, associated with spherules of acicular olivenite and emerald-green crystals of duftite. This characteristic paragenesis is helpful in distinguishing it from beudantite.
