General Notes
Connellite was first recognised at Tsumeb in the early 1980s and reported by Keller and Innes (1986), who considered it to be part of the "linarite paragenesis" (of Keller 1984). It occurs as light- to deep-blue spherical aggregates resembling cyanotrichite.
Connellite is readily confused with munakataite and both minerals are extremely rare. Munakataite may be distinguishable by its association with other selenium minerals, notably plumboselite (Flynn et al. 2016).
