Livingstonite, mercury antimony sulfide, was originally described by Mariano Barcena in 1874 and named for David Livingstone, the Scottish missionary and African explorer. Livingstonite is monoclinic and occurs as radial prismatic (elongate ) aggregates of bright lead-gray, metallic crystals, often intergrown with stibnite. Livingstonite occurs in low temperature hydrothermal veins at the type locality: Huitzuco de los Figueroa (Huitzuco), Mun. de Huitzuco, Guerrero, Mexico. Other notable localities include: Pedrosa del Rey, Leon, Spain; Khaidarkan, Kyrgyzstan; and Matsuo mine, Iwate Pref., Japan.
