摘要
铁钌矿产于我国西藏北部某超基性岩含铂铬矿中,作者对其产状,物理性质,化学成分及X射线分析结果进行了全面的叙述,提供了更详细有价值的矿物学资料。
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. VHN_5 = 609.6 kg/mm^2, 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; a_0 =10.9166 A, C_0 =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.
