    • Beryllium-10 concentrations in depth profiles and surface clasts from terrace surfaces near Littlerock Creek, California

    Metadata Updated: July 6, 2024

    This report summarizes the age-dating results from four terrace surfaces of the Littlerock Creek (map units T3g, T3c, T2, and T1c) that record cumulative strike-slip displacements ranging from 470 to 1080 meters along the Mojave section of the San Andreas Fault. 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 is for fourteen samples. Thirteen samples were collected by Adrien Moulin in 2016 with support from Emery Anderson-Merritt. One sample was collected by Katherine M. Scharer in 2018. Sample preparation and measurements of beryllium ratios by accelerator mass spectrometry (AMS) were completed at the Lawrence Livermore National Laboratory, Livermore, CA, following standard methods.
