    dct:description "This data release contains 54 (U-Th)/He dates acquired from detrital magnetite in stream sediments adjacent to the Taurus Porphyry Cu-Mo(-Au) deposit in eastern interior Alaska's Yukon-Tanana Upland. Measured parameters include Helium-4, Uranium-238, Thorium-232, measured grain geometry factors, and all associated analytical uncertainties. Final (U-Th)/He dates along with uncertainties related to alpha ejection correction are provided." ;
