Description
Summary:Integrated X-ray powder diffraction, scanning electron microscopy, electron probe, and transmission electron microscopy studies have identified the rare contact assemblage calaverite-sylvanite-hessite in a sample of gold ore from the Golden Mile deposit, Kalgoorlie, Australia. The presence of coexisting calaverite-hessite at Kalgoorlie is a non-equilibrium assemblage whereby the stable hessite-bearing assemblage is hessite-sylvanite, which formed from the breakdown of the gamma-phase or chi-phase below 120 degrees C, stutzite+gamma-phase, or sylvanite+stutzite+gamma-phase, as predicted by Cabri (1965).
