Abstract:
These three datasets contain the analytical results of clay mineralogy and 87Sr/86Sr, 143Nd/144Nd, 176Hf/177Hf and D/H (2H/1H) isotope measurements performed on last glacial dust recovered from the NGRIP ice core and fine fractions (<5 and <2 micron) of potential source area samples (modern/last glacial) collected around the Northern Hemisphere. The datasets include Monte Carlo simulation results to calculate squared Mahalanobis distances and mixing calculations between two and three end-members in the Sr-Nd-Hf-dD isotopic space. The fourth dataset contains Zr, Hf concentration and Nd-Hf isotope data of the bulk and various grain size fractions of aeolian loess, paleosol and red clay samples from Europe and SE Asia (China).
