Abstract
Nine pelagic ferromanganese nodules from the South-Eastern Pacific hav e been analyzed by the alpha-radiography technique using the nitrate c ellulose detector LR-1 15 (type 1). The obtained distributions of the total alpha-radioactivity characterize the growth processes in the rec ent time. The surface rinds of the nodules accumulated at 1-15 mm/Ma, a value which is in the normal range . for deep-sea nodules from this region. Some nodules have been analyzed along two different radial dir ections which have rather different rates of accretion.
