Zircon U-Pb data for volcanic ash beds in the Barstow Formation, California probe data 2022
Description
Zircon grains separated from altered ash beds were analyzed to better understand the ages of beds. Isotopic analyses for U-Pb geochronology and trace element geochemistry were performed simultaneously by secondary ion mass spectrometry using the Stanford-USGS SHRIMP-RG ion microprobe housed at Stanford University, USA. Analyses followed the analytical protocol and data acquisition conditions described by Watts et al. (2016). These data are reported in this Release.
