Summary

Select samples were collected from boreholes in Arctic Alaska to determine the U-Pb ages of zircon to determine a maximum depositional age of the geologic units and/or provenance of the zircon in the samples. Samples were collected from the Department of Natural Resources-Alaska Geologic Materials Center in Anchorage Alaska and sent to U.S. Geological Survey-Geology, Geophysics and Geochemistry Science Center, Denver, CO for mineral separation and laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) U-Pb geochronology analyses. The information is this report includes LA-ICPMS analyses conducted between 2016 and 2018 of at least 120 zircon grains or more (if recovered from sample) from twenty samples of rift, Ellesmerian, [...]

Purpose

U-Pb zircon geochronology is an important laboratory technique used in tectonic studies. Detrital zircon geochronology is used here to help identify the source or provenance of the sampled rocks, better resolve the timing and evolution of rifting and tectonic events, test regional paleogeographic reconstructions, understand sedimentary dispersal systems, and resolve age relationships of important hydrocarbon reservoir rocks in federally managed areas of Alaska.
