The stable neodymium isotopic composition of the silicate Earth and chondrites (NERC grant NE/N003926/1)
Neodymium (Nd) concentrations, Nd radiogenic isotopes (143Nd/144Nd) and Nd stable isotopes (d146/144Nd) for chondritic meteorites, terrestrial basalts and mantle rocks, and rock reference materials.

Data Quality
Neodymium isotope measurements were performed using a Thermo-Fisher TritonPlus thermal ionisation mass spectrometer at Durham University. Neodymium was measured as a metal ion in static collection mode using eight faraday cups. Stable Nd isotope ratios are expressed as δ146Nd which is the per mil deviation in the measured 146Nd/144Nd relative to the widely measured Nd reference standard JNdi-1. Long-term reproducibility of the JNdi-1 standard throughout the period of analysis was δ146Nd = 0.003 ± 0.017‰ and 143Nd/144Nd = 0.512100 ± 8 (±2σ; n = 39). See A.J. McCoy-Wes et al., The neodymium stable isotope composition of the silicate Earth and chondrites, Earth Planet. Sci. Letts. 480, 121-132 (2017).
