The principal carriers of platinum-group elements (PGE) in metal-rich black shales: new data from Mo-Ni-PGE black shales (Zunyi region, Guizhou province, south China)
Original language description
We studied Lower Cambrian marine Mo-Ni sulfidic black shales from the Huangjiawan mine in Guizhou Province, south China in which anomalous PGE values (of up to ~1 ppm) were reported. For identification of principal PGE carriers, we used heavy mineral separates which were produced by innovative hydroseparation (HS) technique. A detailed electron microprobe study did not result in identification of discrete platinum-group minerals (PGM). The most abundant sulfides (grainy/not framboidal pyrite, milleriteand gersdorffite) were analyzed for PGE and Re. Grainy pyrite contains up to 490 ppm Pt, 390 ppm Pd and 220 ppm Rh. Millerite contains up to 530 ppm Pt, 320 ppm Pd and 190 ppm Rh. Gersdorffite contains up to 410 ppm Pt, 320 ppm Pd with no Rh detected. Rhenium concentration (up to 610 ppm) was detected only in grainy pyrite. Despite anomalous PGE concentrations the Mo-Ni black shale doesn´t contain any discrete PGE phases. PGE are bound to pyrite and Ni-sulfides (millerite and gersdorffit
