Environments
Zincorinmanite-(Zn) is a new mineral, renamed from rinmanite-(Zn) in 2024, and to date (October 2025) reported
only from the type locality.
Localities
The type locality is the Zincovelesite-6N6S type locality, Nežilovo, Čaška Municipality, North Macedonia. The
sulphide-free metasomatic rocks with chalcophile (having a strong affinity for sulphur) metals from the Nežilovo
ore field belong to a rare kind of ore. A characteristic feature of Nežilovo-type ores is a wide variety of
accessory oxide minerals containing chalcophile elements (Zn, Pb, Sb, Cu and As). The
nolanite supergroup mineral zincorinmanite-(Zn) was
discovered in the Nežilovo ore. The associated minerals are quartz,
baryte, gahnite and
zinc-bearing phlogopite, together
with accessory hematite,
almeidaite, a Pb-analogue of
hydroxycalcioroméite and an insufficiently studied Sb-rich
högbomite supergroup mineral.
Zincorinmanite-(Zn) forms lamellar to tabular subhedral single-crystal grains up to 0.5 mm across and up to
40 μm thick. In reflected light, zincorinmanite-(Zn) is light grey
(MM 89.3.347-356).
