Summary:Enrichment of Au and Ag in massive ore of the Langsele volcanogenic sulphide deposit, northern Sweden, is associated with an intrusive metadolerite vein which can be traced across the ore. It mobilized the Au and Ag, galena and Pb-Sb sulphosalts into fractures and low-P zones. High Hg (average 250 ppm) has given Ag amalgam with native silver Ag and rare AuSb2, aurostibite. Microprobe analyses of amalgam cluster around Au0.45Ag0.45Hg0.10. The composition of ternary amalgam is discussed in connection with the synthetic Au-Ag-Hg system. Native gold, found myrmekitically intergrown with stibnite, has been interpreted as a breakdown product of aurostibite at low-T. [L.G.L.]
