Chenevixite is a relatively rare secondary arsenate
in oxidised zones of
some hydrothermal, polymetallic ore deposits, commonly associated with
olivenite, quartz
and scorodite.
(Mindat)
At the New Cobar Deposit, New South Wales, Australia, chenevixite is often associated with
hematite and segnitite,
and occasionally seen as coatings on goethite. Chenevixite
is one of the first minerals to form in the assemblage, often coated with other arsenates, and invariably
found as a direct alteration product of arsenopyrite.

At the Bali Lo prospect, Ashburton Downs, Western Australia, chenevixite is one of the major components
of the gossan, generally intergrown with olivenite and
sometimes containing irregular quartz fragments.
(AJM 13.1.35)
At Naco, Sonora, Mexico, chenevixite is associated with
malachite, bystromite and ordoñezite.
(HOM)
At the type locality, Wheal Gorland, Cornwall, England, chenevixite is associated with
quartz.

At Mahuba Hill, Nevada, USA, chenevixite is associated with
olivenite and
scorodite.
(HOM)
At the American Eagle mine, Tintic District, Utah, USA, chenevixite is associated with
olivenite and quartz.
