Abstract
Analyses by electron microprobe and secondary-ion mass spectrometry provide information on the relation of Se and Te to other trace elements in arsenian pyrite from Carlin-type and low-sulfidation type epithermal deposits. Correlations between abundances of Se and Te and the other trace elements probably reflect similar behavior in hydrothermal solution and possibly the presence of as yet unknown complexes. Strongest correlations are seen between Te and both Au and Ag in Carlintype deposits and between Te and Ag in epithermal-type deposits; correlations of Au and Ag with Se are uniformly poor. Although correlations with Te are strong, crossplots indicate low Te:Au and Te:Ag ratios of ~0.1 or less, suggesting that Te was not sufficiently abundant to complex either Au or Ag. These results suggest that Se complexes are not present and that Te complexes, though present, are of secondary importance as an agent of metal transport.
