... with the composition Cu 5 FeS 6 ( Frenzel & Otteman, 1967 ; Clark, 1970 ). Rice et al. (1979) named this mineral nukundamite, after its occurrence in the Undu mine, Nukundamu, Fiji Islands. Synthetic idaite was prepared by Ugarte & Burkin (1977) by leaching bornite with ferric sulphate solution...

... Fracture System--a compo- nent of the New Hebrides-Tonga transform dislocation. The best-known deposit is at Nukundamu (Undu Mine) where Zn-Cu-Pb ores occur in a sequence of bedded pumice breccias of early Pliocene age. Pods of massive, mixed- sulphide ore occur in an intensely argillized pipe-like channel...

..., this phase was distinguished from idaite and named nukundamite after the type locality in Nukundamu, Fiji ( Rice et al., 1979 ). The name "idaite" is now reserved for Cu 3 FeS 4 . The reader is referred to Clark (1970) , Rice et al. (1979) , and Seal et al. (2001) for summaries of debates on idaite...

... growth rates of pyrite crystals cause irregular features as observed in natural framboidal pyrite from the Kuroko-type volcanogenic massive sulfide deposit of Nukundamu, Fiji ( Butler and Rickard 2000 ). Such conditions are commonly achieved in laboratory experiments by the addition of S 0 , O 2...
