(Table 1, page 765) D/L Ratios of Amino Acids in Bone Nuclei of Manganese Nodules from the North Pacific Ocean, supplement to: Kvenvolden, Keith A; Blunt, David J (1979): Amino Acid Dating of Bone Nuclei in Manganese Nodules from the North Pacific Ocean. In: Bischoff J.L., Piper D.Z. (eds) Marine Geology and Oceanography of the Pacific Manganese Nodule Province, Springer, Boston, MS, ISBN 978-1-4684-3518-4, Marine Sciences, 9, 763-774


The extent of racemization of isoleucine and aspartic acid has been measured on cetacean ear bones from the center of 8 manganese nodules in order to estimate the ages of the nuclei of the nodules and the rates of accretion of ferromanganese oxide layers. Age estimates obtained range from about 0.4 to 6 m.y., and rates of growth from <1 to about 10 mm/m.y. These rates are consistent with those obtained by other nucleus dating methods (K-Ar and fission track) and by layer dating methods (230Th, 231Pd, 10Be and 26Al).
