The gold-copper deposit at Waschgang (Southern Goldberg mountains, Upper Carinthia) belongs to a type of stratiform, dominantly pyritic deposit, which is hosted by greenschists (“Alpine Kieslager”;Friedrich, 1936). The ores occur as impregnations (ore type 1) and as massive ores (ore type 2) in prasinitic rocks of the Obere Schieferhulle of the Penninic unit. A N−S trending fault zone cuts the ore deposit to the W (Lettenkluft); the position of the displaced part is unknown. The mineralogical composition of type 1 ores is rather monotonous. Pyrite is the most important ore, minor components are chalcopyrite, bornite, sphalerite and magnetite. No visible native gold has been observed in this type of ore. Type 2 ores are dominated by chalcopyrite and are characterized by large amounts of visible native gold. The majority of these ores occur in the vicinity of the Lettenkluft. Type 2 ores carry a great variety of cogenetic mineral inclusions, of which several have been studied with the electron microprobe and investigated by X-ray methods. These include: tetradymite, Bi2Te1.81Se0.13S; hessite, Ag2Te; matildite, AgBiS2; gladite, Cu1.09Pb1.14Bi5.28S9; krupkaite, CuPbBiS6; pekoite, Cu1.09Pb0.97Bi12.56S18; (?) benjaminite, (Ag2.72Cu0.42)3.14 (Bi6.88Pb0.12)7(S11.08Se0.92)12; pavonite, (Ag0.74Cu0.45)1.19(Bi2.86Pb0.27)3.13 (S4.96Se0.04)5; (?) cupropavonite, (Cu0.73Ag0.4)1.13(Bi2.59Pb0.83)3.42S5; and siegenite, (Ni1.07Co1.76Cu0.19)3.02S4. Other components have been determined by qualitative and quantitative microscopy and include: bornite, idaite, mawsonite, sphalerite, millerite, magnetite, hematite, ilmenite, rutile and a variety of silicates. While the layered ore impregnations (type 1 ores) can be considered as being syngenetic with the associated volcanics of Jurassic age, a syn- to postkinematic (Alpidic) crystallization can be postulated for the type 2 ores. These ores are considered as remobilized and reconcentrated parts of the type 1 ores formed in tectonic stress zones. The crystallization of chalcopyrite and included ore minerals occurred during the cooling history of Alpidic metamorphism, for which in this region a maximum temperature of 500°C and pressures between 4–6 kb have been deduced from the mineral assemblage of the surrounding prasinites, consisting of albite with rims of oligoclase, epidote, chlorite, sphene and amphibole (Hock, 1980). Based onSpringer's limit of 300°C as approximately representing the maximum temperature at which natural members of the bismuthinite-aikinite mineral series have been formed, krupkaite and gladite with the intergrown pavonite type phases might have been deposited directly from solutions at or below 300°C. Unmixing of pekoite from gladite probably occurred at or below the same temperature.
