英文摘要	The new mineral tennantite-(Ni), Cu-6(Cu4Ni2)As4S13, has been discovered from the Luobusa Chromitite, Tibet, southwestern China. Tennantite-(Ni) occurs as anhedral grains ranging from 2 to 20 mu m in size. In reflected light microscopy, tennantite-(Ni) is isotropic and appears yellow-greenish grey. Reflectance data for Commission on Ore Mineralogy wavelengths in air for tennantite-(Ni) are: 31.0 (470 nm), 29.6 (546 nm), 29.6 (589 nm) and 29.3 (650 nm). Electron microprobe analysis for holotype material gave the empirical formula (on basis of total cations = 16 apfu): Cu-M(2)(6) (M(1))[Cu-4.00(Ni0.97Cu0.53Fe0.50)Sigma(2.00)vertical bar Sigma(X(3))(6.00)(As2.94Sb1.06)Sigma S-4(12.77). Tennantite-(Ni) is cubic, with space group I (4) over bar 3m (#217), a =10.2957(9) angstrom, V = 1091.4(3) angstrom(3) and Z = 2. By using single-crystal X-ray diffraction, the crystal structure has been determined and refined to a final R-1 = 0.0423 on the basis of 163 independent reflections [F-o > 4 sigma (F-o)]. The calculated seven strongest powder X-ray diffraction lines [d in angstrom (I) (hkl)] are: 2.972 (100) (222), 1.820 (83) (440), 2.574 (28) (400), 1.552 (18) (622), 3.640 (10) (220), 1.880 (10) (521) and 1.287 (7) (800). Tennantite-(Ni) is isostructural with other tetrahedrite-group minerals, and nickel is hosted at the tetrahedrally coordinated M(1) site, along with Cu and minor Fe. The mineral and its name have been approved by the Commission on New Minerals, Nomenclature and Classification of the International Mineralogical Association (IMA2021-018).
