Lorandite
Lorandite is a rare thallium arsenic sulfide. It forms carmine red, transparent to translucent, monoclinic crystals that are sometimes dark lead-gray on the surface. It was named in 1894 for Professor Lorand Eotvos, physicist, mathematician and politician from Budapest. Lorandite forms in low-temperature hydrothermal veins with realgar, orpiment, and barite at the type locality: Crven Dol mine, Allchar, Roszdan, Republic of Macedonia. Other notable localities include the Lengenbach quarry, Imfeld, Valais, Switzerland; Zareh Shuran mine, Takab, West Azarbaijan Province, Iran; Lanmuchang Tl-Hg deposit, Xingren Co., Guizhou Province, Qianxi'nan Autonomous Prefecture, China; and in the USA at the Mercur mine, Mercur district, Tooele Co., Utah; the Getchell mine, Potosi district, Humboldt Co., and the Carlin mine, Lynn district, Eureka Co., Nevada, USA.
