.Earth and Planetary Science Letters 155 1998 15–28 Secular variation of Nd and Pb isotopes in ferromanganese crusts from the Atlantic, Indian and Pacific Oceans
Two ferromanganese crusts from the Indian Ocean and one from the Atlantic Ocean have been analysed for 10Ber 9Be, 143Ndr 144Nd and 208,207,206Pbr 204Pb ratios as a function of depth beneath their growth surfaces. 10Ber 9Be ratios provide growth rate estimates for these crusts between 1.55 and 2.82 m...
