Luminescence Data for Earthquake History of the Needles Fault, Arizona

The following report summarizes the dating results from sedimentary deposits sampled by the USGS Geologic Harzards Team and analyzed at the USGS Luminescence Geochronology Laboratory. Within this report, we detail the methodology used by the USGS Luminescence Geochronology Laboratory to obtain ages including sample preparation methods, luminescence measurement, equivalent dose determination, and dating-related calculations. We recommend that this report be included as the supplementary material for any publication(s) that use the ages within this report. This version supersedes all previous age estimates and reports.
