Environments
Chenite is a rare mineral occurrring occasionally in the oxidised portions of some
lead-copper sulphide deposits,
associated with
caledonite, linarite,
leadhillite, susannite,
elyite, lanarkite,
galena and chalcopyrite
(HOM).
The type locality is the Susanna Mine, Leadhills, South Lanarkshire, Scotland, UK, where chenite was found with
caledonite, linarite,
leadhillite and susannite on
oxidised galena and chalcopyrite
(AM 72.222, Dana).
