Hydrogenetic Fe-Mn deposit (crust) of Rehkämper et al. (2002), Pacific, 4830 m water depth; 80.1 ppm Tl, 32.8 % Mn and 16.9 % Fe. Hydrogenetic crusts, precipitated directly from seawater, have the heaviest ε205Tl (+10.4 to +14.3), unrelated to basin, depth or lead isotopes: constant fractionation of about +21 ε relative to seawater (α = 1.0021). Coordinates from Table 1.
