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

February 20, 2022

Garnet Lu-Hf ages of the schist of Moores Station Formation (112.8 plus or minus 6.9 Ma) and a cross-cutting garnetiferous felsic dike (99.3 plus or minus 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.
