Supplemental Table 1. Radiocarbon Data

Noriega, et al. Stream Channel Offset and Late Holocene Slip Rate of the San Andreas Fault at the Van Matre Ranch Site, Carrizo Plain, California


Notes:
  • Radiocarbon concentrations are given as fractions of the Modern standard, D14C, conventional radiocarbon age and DEL14C, following the conventions of Stuiver and Polach (Radiocarbon, v. 19, p.355, 1977).
  • Sample preparation backgrounds have been subtracted, based on measurements of 14C-free coal (organics), calcite (carbonate) and Whale bone (bone - UCIG# 3778).
  • AMS - d13C values were measured on prepared graphite using the AMS spectrometer. These can differ slightly (typically by 1-3 per mil) from those of the original material, if fractionation occurred during sample graphitization.
  • *Excluded dates. USS: undisturbed surface snail
  • **Bone sample. Excluded.
