Composite samples of three profiles studied by Voegelin et al. (2015) for Tl speciation (illite, jarosite, Tl(III)), analysed for their isotopes; ε205Tl from +5.3 to +12.6, wider than in profiles M and F; the heaviest values (+12.6 and +12.5) belong to a topsoil where all Tl is in illite and a subsoil with half of its Tl as Tl(III). Erzmatt soils (Buus, Swiss Jura), formed on Triassic dolomite with a weathered hydrothermal Tl-As-Fe mineralisation, very rich in geogenic Tl. In both profiles, ε205Tl rises from the C horizons (+2.6 and +0.8) and the bedrock (+1.56) to +8.7 in the Bw horizons, then falls to about +2.5 in the O horizons: according to the authors, repeated redox cycles (oxidative sorption on Mn oxides, weathering of Tl(III) phases, remobilisation of heavy Tl(I) then fixed by illite) and, at the surface, uptake of light Tl by plants; exchangeable Tl of the B horizons is lighter than total Tl (+3.18 to +4.86 in the Bw horizons, Table S6) (Vaněk et al., 2020). Indicative coordinates: those of the M and F pits of Vaněk et al. (2020), location of profiles P1 to P3 not published.
