...Yanjuan Wang; Rujun Chen; Xiangping Gu; Fabrizio Nestola; Zengqian Hou; Zhusen Yang; Guochen Dong; Hu Guo; Kai Qu Abstract Tetrahedrite-(Ni) (IMA2021-031), ideally Cu 6 (Cu 4 Ni 2 )Sb 4 S 13 , is the first natural Ni-member of tetrahedrite group mineral found in Luobusa chromite deposit, Tibet...

... group. Mercury is hosted at the tetrahedrally coordinated M (1) site, along with minor Zn and Fe. The occurrence of Hg at this position agrees both with the relatively large M (1)–S(1) bond distance (2.393 Å) and the refined site scattering. Previous occurrences of Hg-rich tetrahedrite and tetrahedrite...
