Deep-water diagenetic Fe-Mn deposit (crust) of Rehkämper et al. (2002), Indian Ocean, 2100 m water depth; 35.1 ppm Tl, 28.0 % Mn and 12.0 % Fe. Deep-water diagenetic nodules and crusts (0 to +9) are lighter than hydrogenetic crusts, the more so as their Mn/Fe is high (r = 0.97): closed-system adsorption of pore-water Tl, nearly quantitative for the lowest values. Coordinates from Table 1.
