A semiquantitative study of trace elements in pyrite by spark source mass spectrography
1, 2

The trace element assemblages and the relative concentrations of some trace elements have been determined in samples of pyrite by means of spark source mass spectrographic analysis. The samples were from hydrothermal and magmatic, marine, fresh water and metamorphic environments. It is considered, in the case of the samples studied, that hydrothermal and magmatic pyrites can be distinguished from authigenic marine pyrites on the basis of their Ti, V, Mn, Mo, Sn, Ag, and Te contents. Marine pyrites have a higher content of Ti, V, Cr, Co, Ni, Cu, Zn, and Se than fresh water pyrites. It is concluded that pyrite may only be used as an indicator of marine or fresh water environments within the same geochemical province. Metamorphism has little effect upon the trace element content of pyrite.
