Deep-water diagenetic Fe-Mn deposit (nodule) of Rehkämper et al. (2002), Pacific, 5160 m water depth; 103 ppm Tl. 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.
