Triazolite. Guano deposits are the source of several recently discovered new minerals. A bird, the guanay cormorant, Phalacrocorax bougainvillii, is the most likely source of the guano that produced the newly discovered–and exquisitely beautiful–mineral triazolite. Crystals of triazolite overgrow surfaces of hard rock (gabbro) or occur in cavities in aggregates of salammoniac, a rare mineral composed of ammonium chloride. Triazolite is chemically and structurally related to chanabayaite, for which it is a precursor phase. Mineral collectors first found triazolite in the Tarapacá region of Chile. d. Type material is deposited in the collections of the Fersman Mineralogical Museum, Russian Academy of Sciences, Moscow, Russia, registration number 5037/1.
