The mineral was found in heavy mineral concentrates obtained from a weathered chromitite pod included in limonite close to the surface (?floating chromitite?) of a Ni-laterite from the central part of the Loma Caribe peridotite, located within the Cordillera Central of the Dominican Republic (Proenza et al., 2007; Aiglsperger et al., 2015, 2017a, 2017b). Larger grains of PROENZAITE form due to agglutination processes of nanoparticles under supergene conditions (neoformation) at late stages of lateritization. PROENZAITE grains form via agglutination processes of nanoparticles and occur as (i) single grains (up to 100 µm) of rounded shapes (Fig. 1A-D) and/or as (ii) overgrowths around secondary minerals such as ruthenian hexaferrum (replacing it over time) (see Aiglsperger et al. 2017a for details).
