Abstract
A listwaenite-hosted Ni-As-Sb-S assemblage occurs in the Stan Terg Zn-Pb(Ag) district within the Vardar Zone structure and is closely related to a Neogene calc-alkaline and volcanic-intrusive complex. In this paper, results of gersdorffite chemical analyses performed using electron microprobe analysis from Vllahi, Melenica and Mazhiq is presented. Small irregular inclusions of gersdorffite from Vllahi are enclosed in galena and shows enrichment in Co (up to 3 wt.%) in comparison to Co-free Melenica and Mazhiq samples. In Melenica the initial Ni association is replaced by gersdorffite and later by Sb-bearing gersdorffite. Mazhiq samples are dominated by oscillatory zoned crystals of gersdorffite and Sb-rich gersdorffite rimming arsenopyrite cores or irregular masses filling free spaces between euhedral crystals of arsenopyrite. Zoning is related to variable As (up to 42 wt.%), Sb (up to 15 wt.%) and Fe (up to 9 wt.%) indicating fluctuations of arsenic and antimony fugacity in hydrothermal fluids. Melenica and Mazhiq gersdorffite performs strong replacement trend of a mixture of Co and Ni by Fe. In addition, extensive substitution of As by Sb led to deposition of intermediate member of gersdorffite-ullmannite series, maximum content of Sb reaches 0.47 apfu.
