Environments:
Fülöppite is a rare mineral of hydrothermal origin,
(Webmin, HOM)
associated with zinkenite, semseyite,
fizélyite, andorite,
freieslebenite, geocronite,
boulangerite, jamesonite,
cinnabar, sphalerite,
marcasite, quartz and
dolomite
(HOM).
At Baia Mare, Maramures, Roumania, fülöppite has been found with
sphalerite,
quartz, dolomite,
sulphur and zinkenite
(AM 15.201-202).
At Wet Swine Gill, Coombe Height, Caldbeck, Allerdale, Cumbria, England, UK, the quartz-antimony vein contains an early antimony-iron-arsenic
primary assemblage comprising
stibnite, berthierite and
arsenopyrite, and a later
antimony-lead assemblage including
zinkenite, fülöppite and
semseyite, in massive white quartz
(JRS 7.1:36).
