U-Pb and 40Ar/39Ar Geochronologic Data for Selected Rocks from the Western Alaska Range, Alaska
February 22, 2022
This dataset includes four tables with isotopic data and ages for selected igneous bedrock samples collected in 2001 through 2003 from the Western Alaska Range, southcentral Alaska: (1) the concentration of uranium (U) and thorium (Th), ratios of multiple isotopes of lead (Pb) and U, and the age of multiple analytical aliquots, or fractions, of zircon for each sample; (2) the 40Ar/39Ar analytical data and interpreted ages for each rock sample; (3) the sample location, rock characteristics, and interpreted ages for each sample; (4) a data dictionary table, provided as a reference guide for the user.

Cretaceous to Oligocene magmatic and tectonic evolution of the western Alaska Range: Insights from U-Pb and 40Ar/39Ar geochronology
New U-Pb and 40Ar/39Ar ages integrated with geologic mapping and observations across the western Alaska Range constrain the distribution and tectonic setting of Cretaceous to Oligocene magmatism along an evolving accretionary plate margin in south-central Alaska. These rocks were emplaced across basement domains that include Neoproterozoic to Jurassic carbonate and siliciclastic strata of the Fare
