...John F. Riley Abstract Examination of a mineral sample from Chibuluma (one of the Rhodesian Selection Trust Group mines on the Northern Rhodesian Copperbelt) proved it to be a high cobalt-bearing pyrite, approximately midway between the two end members of the binary system FeS 2 (pyrite) — CoS 2...

... transition metals, and pyrite (FeS 2 ), cattierite (CoS 2 ), vaesite (NiS 2 ), and hauerite (MnS 2 ) crystallize in the pyrite-type structure. However, there are few studies on the sulfur isotope fractionation in these disulfides. So studying the isotope fractionation between them provides the opportunity...

... with an atomic ratio (Fe + Co + Ni)/(As + S) of 1:2 and a S:As ratio of 3:1. Two isothermal sections were investigated, 500° and 650°C. The 500°C experiments resulted in the formation of arsenopyrite, cobaltite, cattierite, gersdorffite, linnaeite, monosulfide solid-solution, pyrite, siegenite and vaesite...

American Mineralogist (1945) 30 (7-8): 483–497.
.... At the Shinkolobwe mine in the Belgian Congo, CoS 2 having a pyrite structure is now known. To this mineral is assigned the name cattierite. Material approaching NiS 2 is composition and having a pyrite type of lattice has been found in the Kasompi mine of the Belgian Congo. This mineral is tentatively called...

...J. R. Craig; D. J. Vaughan Abstract Cattierite (CoS 2 ) specimens from the type locality contain disulfides deposited in the sequence pyrite (<0.9 percent Co) → cobaltiferous pyrite (15-20 percent Co) → cattierite (3.5-6 percent Fe and 2-8 percent Ni). Cattierite formation was accompanied...

... is native silver-chalcocite-bornite-galena-linnaeite-sphalerite-cattierite-pyrite. Native copper appears prior to chalcocite at a pH above 6.6 if the initial copper concentrations in the waters are 800 ppm or at a pH above 7.2 if copper concentrations are 100 ppm. Linnaeite does not precipitate at pH values...

...% in the Co ore zone ( Fig. 2C ) and 28% in the Co-Cu ore zone ( Fig. 2D ). The ores also contain up to 2% of a 10–100 μm sulfide mineral in the Ni-Co cattierite-vaesite solid solution series, associated with pyrite and iron oxides ( Fig. 2B ). The matrix is quartz (1%–70%), Fe- (Mn-) oxides (up to 26...

... is extended on cooling, reaching a maximum (CuCo 2 S 4 ) at approximately 500 degrees C. Below 507 degrees C covellite is stable and coexists in the sulfur-rich portion of the system with copper-bearing cattierite. Below 500 degrees C the major changes involve a change in stable assemblages (at approximately...

..., such as a pyritic shale, or mixed with a euxinic (H 2 S-rich) fluid. These processes, however, would lead to either monomineralic Co sulfide deposition or a paragenesis opposite to that commonly observed, e.g., linnaeite followed by cattierite (see Fig. 7 d). Although processes like sulfidation (replacement of Fe...

... ). The earliest ore minerals to deposit were Cu-bearing framboidal pyrite and slightly later Co-Ni–bearing pyrite. Cattierite deposited contemporaneously with the Co-Ni–bearing pyrite ( Cailteux et al., 2005 ). This preceded deposition of chalcopyrite, followed by bornite + carrolite and, finally, chalcocite ( El...
