Triazolite is a copper mineral that forms when chilean guano comes in contact with chalcopyrite-bearing gabbro, a dark, coarse-grained rock with crystalline texture that forms deep below the Earth’s surfaceThe first specimens containing triazolite were collected in 2008

The path to formal acceptance of triazolite as a mineral began in 2008 when German mineral dealer Gunnar Färber first collected specimens containing triazolite and chanabayaite (the product of natural alteration of triazolite) in a guano deposit situated on the lower part of the steep northern slope of Pabellón de Pica Mountain, 1.5 km south of Chanabaya village, Iquique Province, Tarapacá Region, Chile. The Guanay cormorant (Phalacrocorax bougainvillei) is the most likely producer of this Chilean guano. This guano deposit is unique because it is in contact with chalcopyrite-bearing gabbro, a dark, coarse-grained rock with crystalline texture that forms deep below the Earth’s surface. Such contact allows numerous organic minerals of copper to form, and provides a suitable substrate upon which crystals of triazolite can grow.

Abellaite is a lead carbonate mineral discovered in the Eureka uranium mine in northern Spain in July 2010. [2]

The mineral was verified by the IMA/CNMNC in December 2015 and named in honor of its founder, Catalan gemmologist Joan Abella i Creus.
