About NukundamiteHide

Empirical formulae are:
Cu3.37Fe0.66S3.97 (type material); Cu3.39Fe0.61S4 (synthetic material).
Crystal System:
Nukundamite is stable within a highly limited range of a(Fe2+)/a(H+) activity ratio, S2 and O2 fugacities, at temperatures between 501° and 224°C at very high sulfidation states (Seal et al., 2001; Esra Inan and Einaudi, 2002).
It may be replaced by chalcopyrite and bornite.

One of the Cu-Fe sulfides that has been referred to as the grandfathered but inadequately described idaite; type locality nukundamite was first called "idaite" (cf. Rice et al., 1979).

Classification of NukundamiteHide


2 : SULFIDES and SULFOSALTS (sulfides, selenides, tellurides; arsenides, antimonides, bismuthides; sulfarsenites, sulfantimonites, sulfbismuthites, etc.)
C : Metal Sulfides, M: S = 1: 1 (and similar)
A : With Cu

9 : AmBnXp, with (m+n):p = 1:1

3 : Sulphides, Selenides, Tellurides, Arsenides and Bismuthides (except the arsenides, antimonides and bismuthides of Cu, Ag and Au, which are included in Section 1)
