Luminescence Data for: The Parguera fault: Possible Quaternary reactivation of a bedrock fault in southwest Puerto Rico

July 21, 2026

The following report summarizes the dating results from sedimentary deposits discovered during paleoseismic investigations of Puerto Rico. 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.
