| Abstract: | Aurostibite 1s reported for the first time in China from the Yangshanzhu-ang gold deposit, Pingjiang, Hunan Province. Associated minerals are nativegold, stibnite, antimony, arsenopyrite, pyrite, bournonite, etc. It occurs asvery fine grains measuring 0.02-0.05mm in diamter. Aurostibite is greyish-black in colour, with dull lustre, opaque, no clea-vage, Hv=211-246kgmm~2(20g). In reflected light it is white and isotropic.Reflectivity: 63. 29 (405nm), 63. 04 (480nm), 63. 00 (546nm), 62. 57 (589nm), 61. 86(656nm). |
