| 摘 要： | Argentian mercurian gold,golden-yellow in colour,is a variety of native gold containing Ag and Hg,coccurring as hexagonal and tetragonal crystals in hairy,milk-droplet or irregular forms.Its microhardness Hv=91kg/mm^2,equivalent to 3.04on Mons‘scale,and the reflectance is 70.35%(589nm).Chemical analysis gave:Au 56.05-67.33,Ag18.29-31.06 and Hg 10-14.82%,as well as minor Cu.In a few samples Bi or Fe was also detected.The simplified formula is (Au0.52Ag0.36Hg0.09Cu0.02)0.99.X-ray analysis suggests the mineral is of isometric system,with space group=Oh^5-Fm3m,a0=0.40803nm,V=0.06739nm^3,and Z=4.Argentian mercurian gold occurs in a Ag-multimetal deposit at Xiacun,Baiyu County,Sichuan Province,As observed in the mining district,the mineral is distributed along the fissures of the main metallic minerals pyrite,tetrahedrite,chalcopyrite,arsenopyrite,galena,sphalerite,etc.,or in the sulfide veinlets developed in the.fissures of these minerals.Also found in the mineral deposit are native gold,argentite,sulvanite,bournonite,boulangrite,etc.

| Abstract: | Argentian mercurian gold, golden-yellow in colour, is a variety of native gold containing Ag and Hg, occurring as hexagonal
and tetragonal crystals in hairy, milk-droplet or irregular forms. Its microhardness Hv=91kg/mm2, equivalent to 3.04 on Mons’ scale, and the reflectance is 70. 35% (589nm). Chemical analysis gave: Au 56.05-67.33, Ag 18.29-31.06
and Hg 10–14.82%, as well as minor Cu. In a few samples Bi or Fe was also detected. The simplified formula is (Au0.52 Ag0.36Hg0.09Cu0.02)0.99. X-ray analysis suggests the mineral is of isometric system, with space group =O
