Summary

This report summarizes the age-dating results from two alluvial fan surfaces (map units Qyf2 and Qyf3) that are broken by strands of the Cucamonga Fault, in southern California, at Day Canyon and Etiwanda Canyon. Within this report are detailed the methodology used to collect samples of rock and sediment, determine concentrations of cosmogenic beryllium-10 in purified quartz isolated from the samples, and use those nuclide concentrations to calculate surface exposure ages. This report should be used as the supplementary materials for any publication(s) that uses the nuclide concentrations and/or ages reported herein. This version supersedes all previous age estimates and reports.

Purpose

This report is for twelve samples from the alluvial fans at Day Canyon and Etiwanda Canyon in Rancho Cucamonga, California. Samples were collected by Devin McPhillips in 2017 with support from Katherine Scharer and Katherine Kendrick. Sample preparation and measurements of beryllium ratios by accelerator mass spectrometry (AMS) were completed at the Purdue Rare Isotope Measurement (PRIME) lab in West Lafayette, IN, following standard methods.
