【Abstract】 Since 1976 several grains of tieliaoite have been discovered in chromium ores in ultrabasic rocks of North Tibet. After a series of preliminary study, tieliaoite is confirmed as a new mineral. Chemical composition （electron probe analyses） （%）: Ru 37.9-70.1, Os 0.5-13.2, Ir 0.3-7.5, Rh 0-4.1, Fe 20.3-46.9, Co 0-2.7, Ni 0-1.0. VHN₅ = 609.6 kg/mm², Reflectivities （%）: 480 nm, 53.2-41.5; 546nm, 58-44.1; 589nm, 58-44.2; 656nm, 62-46. Hexagonal system. Strong X-ray diffracting lines:3.3936（5）, 2,0464 （10） , 1.1340 （5） , 0.8752 （8） , 0.8127 （5） . Lattice parameters; a₀ =10.9166 A, C₀ =8.6713A. It is named as tieliaoite according to the main components iron and ruthenium in Chinese. The mineral sample is preserved in the Institute of Complex Utilization of Mineral Resources.更多还原
