USGS Geochron is a database of geochronological and thermochronological dates and data. The data set contains published ages, dates, analytical information, sample metadata including location, and source citations. The following analytical techniques are represented in the data set: 40Ar/39Ar, K-Ar, U-Th-Pb, Sm-Nd, Rb-Sr, Lu-Hf, fission track, luminescence, U-series in situ, (U-Th)/He, and Re-Os. This data set incorporates data previously hosted in the National Geochronological Database (Sloan and others, 2003), as well as data from published journal articles and ScienceBase data releases. These data are primarily from the United States, but data from other parts of the world are also included. First posted January...

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...
