Selected fervanite specimens, however, may exhibit radiating clusters to 0.
Associated minerals commonly include opal, tyuyamunite, kazakhstanite, fervanite and minor barite.
Fervanite, minor schubnelite, hewettite and tyuyamunite are commonly associated.
The mineral is not particularly common, but occurs, in general, on most specimens of kazakhstanite, fervanite and tyuyamunite.
Tyuyamunite has also been found as relatively abundant, pale yellow dustings coating Kazakhstanite and fervanite on brecciated jasperoid fragments from the 5,425 bench at location 2.
