Doyleite, a triclinic polymorph of nordstrandite, beyerite
and gibbsite, was described as a new species jointly from Mont Saint-Hilaire [type locality 1] and from the Francon quarry [type locality 2] (Chao et al.
Bismuthcontaining minerals found include native bismuth, bismite, bismutite, bismuthinite, and beyerite (Jahns and Wright, 1951).
Sinkankas (1997) also reports the presence of bismuth-containing minerals including clinobisvanite, namibite, and beyerite.
It is commonly associated with other bismuth minerals including native bismuth, bismuthinite, bismutite, bismite, beyerite, eulytite, pucherite, schumacherite and clinobisvanite.
Namibite associated with native bismuth, bismutite, beyerite and eulytite has been identified from the Evans-Lou pegmatite near Poltimore, Quebec (Grice et al.
1994) report an occurrence of namibite from the Elias mine, Jachymov, Krusne hory, Czech Republic, where it is found in fragments of quartz gangue with eulytite, beyerite, bismutite and pucherite.
Associations include bismutite, beyerite, hechtsbergite, eulytite and mixite.
It is found in quartz cavities associated with native bismuth, beyerite, bismite, bismutite, clinobisvanite pseudomorphs after pucherite, and other oxidized Cu minerals.
At this locality, namibite occurs in small pod-like masses in quartz-rich "pocket-pegmatite" zones as fine-grained, emerald-green masses intergrown with tan clinobisvanite and beyerite.
