Common lead isotopic measurements in silicate glasses and minerals by laser ablation double-focusing SC-ICPMS (2017) This dataset is related to a 2017 journal article by A. J. Pietruszka and L. A. Neymark titled "Evaluation of laser ablation double-focusing SC-ICPMS for “common” lead isotopic measurements in silicate glasses and minerals" that is published in the Journal of Analytical Atomic Spectrometry (doi:10.1039/c7ja00005g).

Fractionation factor and ratio data in between NIST glass and natural scheelite as well as isotope dilution Sm-Nd scheelite data are also included. Scheelite is from two ore deposits within the Stibnite-Yellow Pine mining area, and analyses yielded bimodal U-Pb ages with major growth of scheelite in the range of 61.3 ± 4.1 to 55.1 ± 3.8 Ma and a second growth event involving both scheelite and stibnite at 45.8 ± 2.6...
