...Shi-Ji Zheng; Xiang-Ping Gu; Zhong-Jie Bai; Zhong-Kun Zhang Abstract Zhonghongite (IMA2023-046), ideally Cu 29 (As,Sb) 12 S 33 , is a new mineral discovered in the high-sulfidation vein of the Jiama deposit (E 91°45′, N 29°42′), southern Tibet, China. It forms complex intergrowths with watanabeite...

Reflected-light photomicrograph (a) and backscattered electron (BSE) images (b–d) for zhonghongite. (a) Light green zhonghongite has similar reflecting color to watanabeite. (b–d) Zhonghongite occurs between watanabeite and tetrahedrite and their boundaries are clear. Enr = enargite; Wa = watanabeite; Zhh = zhonghongite; Td = tedrahedrite; Au-Ag-Tel = Au-Ag tellurides.
