Apatite and zircon fission track data from the western Brooks Range of Arctic Alaska

The attached data are apatite and zircon fission track measurements from rock samples collected across the western Brooks Range. Table 1 contains descriptive information on each sample. Tables 2a, 2b, 2c, 2d and 2e contain single grain, apatite fission track age data for samples from each of five datasets that comprise the overall apatite fission track age dataset. Tables 3a, 3b, 3c, and 3d contain apatite fission track length data for samples from four of the five datasets that comprise the overall apatite fission track length dataset. The oldest of the five datasets has no accompanying track length data. Table 4 contains summary information for each of the apatite fission track age samples. Table 5 contains summary information for each of the apatite fission track length samples. Tables 6a and 6b contain single grain, zircon fission track age data for samples from each of two datasets that comprise the overall zircon fission track dataset. Table 7 contains summary information for the zircon fission track age data.
