Minor iron admixture is also present.[2] It is also one of a few currently known minerals containing ammine groups, including also ammineite, joanneumite and shilovite.[4][5][6] All the minerals are rare and were found in a single guano deposit in Chile, called Pabellón de Pica.[7] A similar natural phase, formula NaCu2Cl3[N3C2H2]2[NH3]2·4H2O, likely a precursor of chanabayaite, is described by Zubkova et al. 2016.[8] Crystal structureThe main features of the crystal structure of chanabayaite are:[2]
AssociationChanabayaite coexists with halite, joanneumite, nitratine, salammoniac and paragenetically-unrelated chalcopyrite. Chalcopyrite is present in an amphibole- and plagioclase-bearing gabbro, that conctacts the guano deposit.[2] FormationThree suggested processes account for the formation of chanabayaite:[2]
