The new mineral tennantite-(Ni), Cu 6 (Cu 4 Ni 2 )As 4 S 13 , has been discovered from the Luobusa Chromitite, Tibet, southwestern China. Tennantite-(Ni) occurs as anhedral grains ranging from 2 to 20 μm in size. In reflected light microscopy, tennantite-(Ni) is isotropic and appears yellow-greenish grey. The reflectance data for the four COM wavelengths 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
