Hauerite is a low-temperature mineral commonly associated with volcanic waters, in clay
deposits rich in sulphur, and from decomposed extrusive rocks. Associated minerals include
sulphur, realgar,
gypsum and calcite
(HOM, Webmin).
Localities
The type locality is Kalinka, Vígľašská Huta - Kalinka, Detva District, Banská Bystrica Region, Slovakia.
At the Destricella Mine, Raddusa, Metropolitan City of Catania, Sicily, Italy, hauerite crystals to 4 cm and larger were found
embedded in a layer of clay at 50 metres depth under layers of
gypsum, sulphur and
limestone. The mine is now totally inaccessible
(Minrec 43.2.188-190).
In Texas, USA, hauerite is found in salt domes
(Dana).
