...W. S. Wise Abstract Parnauite and goudeyite were found with other secondary copper minerals in the middle adit level of the Majuba Hill Mine, Pershing County, Nevada. Parnauite occurs as pale-blue fans and rosettes of lath-like crystals up to 1 mm in length, as green scales and crusts, and drusy...

... that there are also pseudomorphs of cornwallite after euchroite or complex pseudomorphs of cornwallite + cornubite + olivenite after euchroite. Euchroite at the site studied is younger than chalcophyllite and strashimirite; the temporal relationship to parnauite is more complex, as euchroite can be older or younger...

.... Similar disorder is known for parnauite, and is deduced for other members of the cyanotrichite group (cyanotrichite, carbonatecyanotrichite and khaidarkanite). Group members all share the Cu–Al ribbon module but have interlayer rods of different compositions and topologies; thus, they form a merotypic...

... on Moh's scale. Forêtite is found in direct association with bariopharmacoalumite, cyanotrichite, parnauite, chalcophyllite and mansfieldite in an Al-rich assemblage which is presumed to have formed under acidic conditions. It is biaxial; the average refractive index measured in white light on aggregates...

... assignments for the chemically related copper arsenate–sulfate parnauite ( Frost et al. , 2009 ), bands ranging between 745 and 866 cm −1 could be attributed to the stretching of (AsO 4 ) 3− groups. In particular, the bands at 866 and 826 cm −1 could be related to the ν 1 (AsO 4 ) 3− symmetric...
