Bornite, chalcopyrite, idaite, covellite, yarrowite, spionkopite, anilite, digenite, djurleite, and chalcocite have been identified in quartz veins from the Vielsalm area. Stavelot Massif, Belgium. The identification of these copper sulfides is confirmed by electron-microprobe analyses. The association of primary sulfides indicates that the bornite-bearing quartz veins crystallized above 300-350 degrees C, whereas the chalcocite-bearing quartz veins crystallized below 200 degrees C. Relations among sulfides indicate the occurrence of two sequences of transformation, responsible of the formation of secondary sulfides: chalcocite-H double right arrow chalcocite-M double right arrow djurleite double right arrow low digenite or (anilite + djurleite) double right arrow yarrowite + spionkopite double right arrow covellite + oxidation minerals, and bornite double right arrow idaite + chalcopyrite double right arrow covellite + oxidation minerals. The crystallization of chalcocite-M, djurleite, and low digenite or (anilite + djurleite) took place between 103.5 and 72 degrees C. The associations idaite + chalcopyrite, yarrowite + spionkopite, and covellite + oxidation minerals, were produced under meteoric conditions. The source of Cu and of the other elements present in the quartz veins must be sought in the host chloritoid-bearing schists. [less ▲]

A sample from the Kibingo granitic pegmatite, Rwanda, shows a striking assemblage of an alluaudite-group mineral with heterosite. The core of alluaudite s.l. is strongly pleochroic in blue green to pinkish grey hues, and is rimmed by an irregular border, weakly pleochroic in yellow brown to greenish yellow tints. The pleochroic core is very rich in Na (up to 9.35% Na2O), whereas the yellowish green border is depleted in Na (3.75% Na2O) and more oxidized. The decrease of the Na contents is not accompanied by significant variations of the ratio Fe-tot/(Fe-tot + Mn). This mechanism represents the progressive transition of hagendorfite to alluaudite sensu stricto, and results from an oxidation, Na+ + Fe2+ --> rectangle + Fe3+. Heterosite exhibits cracks that are parallel to one of the cleavage directions, and that are favorable to the development of a product of alteration, identified as cyrilovite. Heterosite shows a chemical composition close to the idealized formula (Fe0.853+Mn0.153+)PO4, with a Mg content constant and quite low, i.e., 0.023 Mg apfu. The Kibingo heterosite seems to be the Fe-richest member known so far. The heterosite corresponds to an oxidized Fe-rich member of the triphylite - lithiophilite series, a member that was initially in equilibrium with the primary hagendorfite. The ratio Fe-tot/(Fe-tot + Mn) of the two minerals of this assemblage is different: the value is about 0.70 ire hagendorfite, and 0.85 in the former triphylite. The temperature of formation of hagendorfite is estimated at about 600degreesC. Contrary to the information in the literature, the Kibingo pegmatitic body differs from the amblygonite pegmatite of Mwaka and could be a poorly evolved neighboring pegmatitic lens. [less ▲]
