Other hydrothermalSb-As-Tl
- Type
- Low-temperature hydrothermal
A unique Sb-As-Tl deposit whose main minerals are pyrite, stibnite, orpiment and realgar. The Crven Dol mine worked the Sb-poor, As- and Tl-rich part of the deposit. Thallium is carried by lorandite (TlAsS2), and 45 rare thallium minerals have been identified there.
