Lanmuchang (Guizhou), Hg-Tl deposit where Tl forms its own minerals (lorandite), mined for Hg for over 350 years then for lorandite alone in the 1990s until 2000; poorly developed soils (Oxisols) derived from weathering of mineralised outcrops, rich in Fe2O3 (100 to 200 g/kg). Sediment with natural Tl (30 mg/kg), of the same composition as the nearby arable soil (Kersten et al., 2014). Indicative coordinates of the deposit.
