Hauyne is common in small quantities as phenocrysts in phonolite and monchiquite (Loughlin and Koschmann, 1935; Birmingham, 1987).
The sodalite family is composed of the minerals sodalite, nosean, hauyne and lazurite; cubic aluminosilicate species with the formula [(Na,Ca).
Three of the four members of the sodalite group - sodalite, hauyne and lazurite - are known to occur at Monte Somma/Vesuvius, while unconfirmed tests suggest that the fourth member, nosean, is also present.
Typical associated minerals include a sodalite-group mineral (sodalite, lazurite, hauyne or nosean), nepheline, diopside, sanidine, pargasite, phlogopite-biotite and calcite.
