Garnet Lu-Hf Ages and Isotope Data for the Stibnite, Idaho Area

Garnet Lu-Hf ages of the schist of Moores Station Formation (112.8 ± 6.9 Ma) and a cross-cutting garnetiferous felsic dike (99.3 ± 2.0 Ma) are the main contributions of this dataset. Ages are determined with lower-intercept isochron plots from multiple garnet and whole rock fractions, and garnet model age plots show distribution of garnet fractions with excluded points grayed out. Elemental concentrations of Lu and Hf, isotopic ratios, and epsilon Hf (initial and today) values are also included for each sample in table form. Samples are from 2 miles north-northwest of the abandoned townsite of Stibnite, Idaho.
