The thallium-rich ore bodies extend over an area of about 1.5 square km. They contain lorΓ‘ndite as the major ore mineral. Major geogenic pollution affecting human health has been documented.
The deposit was formed by bio-metallogenesis (involving the enrichment of Tl in micro-paleo-animals in rocks and ores, bio-fossil casts in Tl-rich ores, the involvement of bio-sulfur in minerogenesis and the enrichment of bio-genetic organic carbon in Tl ores) and subsequent hydrothermal reworking (Zhang et al., 2007).
The deposit was originally formed in the Late Permian. Subsequently, hydrothermal reworking took place during the Middle Triassic (Zhang & Zhang, 2000).
