Objective Thallium has been used as an indicator element in geochemical exploration of searching for hydrothermal gold deposits. However, the T1 minerals and mineralization are rare in nature. Lorandite TlAsS_2, a relatively uncommon mineral, has been dominantly discovered in some Carlin gold deposits, and minor SbHg, U and Pb-Zn-Ag deposits. It is of hydrothermal origin and was typically formed at relatively low temperatures. These relationships between these deposits containing lorandite and intrusions remain a highly
