Two ferromanganese crusts from the Indian Ocean and one from the Atlantic Ocean have been analysed for 10Be/:9Be, 143Nd/144Nd and 208,207,206Pb 204Pb ratios as a function of depth beneath their growth surfaces. 10Be/9Be ratios provide growth rate estimates for these crusts between 1.55 and 2.82 mm M...
