Abstract

The sulphur isotope compositions of sulphide ore minerals from the Drau Range varies considerably, both on a regional and local scale; delta (super 34) S values from +2 and -250/00 with a mean around -170/00, are probably related to both local bacteriogenic and thermal reduction of late Triassic marine sulphate. There is a strong depletion of (super 34) S in botryoidal sphalerite, ranging between -24 and -320/00, apparently correlated with the crystal mode (wurtzite-sphalerite fibres) and the enrichment of the trace elements Fe, As, Tl and Ge. Sphalerite generations of specific CL, colour and closely related trace element contents are correlated district wide. Enrichment of Cu as a trace element in orange-luminescing sphalerite is negatively correlated with Fe, As, Tl and Ge, and therefore suggests leaching of Cu from late Permian to early Triassic continental red beds. Some S may also have been transported with a metal-rich brine.
