Paulišite is a new mineral, approved in 2023 and to date (March 2025) has been reported only from the type locality.

Localities

At the type locality, the Staročeské Lode, Kutná Hora, Kutná Hora District, Central Bohemian Region, Czech Republic, paulišite was discovered in the underground workings at the abandoned mine adit of the first level of the Lode, associated with hydrozincite and aragonite (holotype sample) or calcite, aragonite, hydrozincite and monohydrocalcite (other samples). The paulišite occurs as crusts, up to 1 cm thick, formed by parallel or radial aggregates of acicular crystals up to 5 mm long. Paulišite is colourless to white, with a white streak, and transparent with a vitreous lustre.
Along with minrecordite, skorpionite and znucalite, paulišite is the fourth mineral containing Ca, Zn, and (CO₃) groups as species-defining elements. Its origin is related to the supergene alteration of ore deposits following the mining activity, probably at low temperature and basic pH conditions (AM 110.3.480-488).
