Domitrovicite is a new mineral, approved in 2023 and to date (June 2026) reported only from the type locality.
Since the discovery of the first glycolate mineral, lazaraskeite, from the western end of Pusch Ridge in the Santa Catalina Mountains, Tucson, Arizona, USA, at least eight other glycolate minerals have been identified from the same locality, namely domitrovicite, fuchunite, glecklerite, jimkrieghite, lianbinite, puschridgeite, rasmussenite and stanevansite.

Localities

At the type locality, Western end, Pusch Ridge, Pima County, Arizona, USA, both domitrovicite and puschridgeite were discovered in cracks or fractures in a heavily fractured leucogranite, one to two metres below the rock surface. Minerals associated with domitrovicite include stanevansite, chrysocolla, rasmussenite and quartz. Domitrovicite occurs as bladed or prismatic crystals up to 0.40 3 0.05 3 0.02 mm (CJMP 64.275-294).
Domitrovicite has been found with rasmussenite, lazaraskeite and muscovite (Mindat photo).
