Calcite U-Pb analytical results documenting the evolution of Miocene normal and dextral faulting in the lower Colorado River region near Blythe, California, USA

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2023-06-12T00:00:00Z
Faults in the study area are commonly coated with synkinematic calcite, and we use laser ablation inductively-coupled mass spectrometry (LA-ICP-MS) U-Pb geochronology to determine the timing of this mineralization. This dataset presents the results of those analyses and age determinations of different samples and sample subsets. These datasets are associated with a manuscript accepted for publication: Mavor, S.P., Bennett, S.E.K., Crow, R.S., Singleton, J.S., Langenheim, V., Stockli, D., Stelten, M., Brickey, T.A., Sr., Umhoefer, P.J., and Beard, L.S., 2023, Evolution of Miocene normal and dextral faulting in the lower Colorado River region near Blythe, California, USA: Geosphere, v. 19, https://doi.org/10.1130/GES02608.1.
