142Nd/144Nd variations in terrestrial samples ranging from Proterozoic to present
This dataset contains neodymium isotope data for MORBs, OIBs and samples of the Baltic Shield in Norway. It lists dynamically obtained 142Nd/144Nd values using the method of the publication below, and dynamic 143Nd/144Nd values which were obtained separately. 142Nd/144Nd data for JNdi, the standard used as the terrestrial reference point, as well as NdA, the Harvard house standard, and Nd-β, the Caltech standard, are also included. All data were collected on the IsoprobeT thermal ionization mass spectrometer (TIMS) at Harvard University, Cambridge, MA. The purpose of the study was to constrain 142Nd/144Nd variability in terrestrial samples, throughout the Proterozoic to modern-day.
