Name:
Named in 2012 by Dan Topa, Emil Makoviky, Gheorghe Ilinca and Herbert Dittrich as a portmanteau of "cupromakovickyite" and "cupropavonite", chemically and structurally related minerals of which it is ideally a 1:1 interstratification. Pavonite is named for Martin Alfred Peacock; pavo = peacock in Latin.
