Age-progressive, linear seamount chains in the northeast Pacific appear to have formed as the Pacific plate passed over a set of stationary hotspots; however, some anomalously... -
(Table 1) Sr-Nd-Pb isotopic compositions of samples from ODP Hole 183-1137
Basalts forming the floor of the Indian Ocean are geochemically distinct from those of the Atlantic and Pacific Oceans. These differences have been attributed to a deeply... -
Sr, Nd and Pb isotopic ratios of igneous rocks from DSDP holes (Table 1)
Igneous rocks from the Philippine tectonic plate recovered on Deep Sea Drilling Project Legs 31, 58 and 59 have been analyzed for Sr, Nd and Pb isotope ratios. Samples include... -

Ages are calendar years before present (1950) on the layer-counted timescale (Meese et al., 1997, file countage.dat). Data on possible dust source regions are given in file... -
Neodymium and lead isotopes from manganese crust G9632-47 (ROM32)
The ages are calculated for the respective mean depths. Depending on the different growth rates of the crusts, samples correspond to different age intervals. -
Lead and neodymium isotope time-series for manganese crust D27_2-1
Ages were calculated using growth rates derived by 10Be/9Be ratios and constant Co-flux model. For compatibility all ratios were normalized to the NIST SRM981 values of Galer...
