Tabular uranium-lead and trace-element compositional data of zircons and whole-rock geochemistry of plutonic rocks in the Sierra Nevada, California
This dataset consists of zircon uranium-lead (U-Pb) isotopic compositions, ages, and trace-element compositions in addition to whole-rock chemical compositions from plutons within the Sierra Nevada, California. These samples primarily collected from 2015 to 2023, although some legacy data are included. Zircon crystals were analyzed using the Sensitive High-Resolution Ion Micro-Probe Reverse Geometry (SHRIMP-RG) managed jointly by the U.S. Geological Survey and Stanford University. Uranium-lead (U-Pb) zircon geochronologic and trace element compositions were obtained for 35 samples of Triassic to Cretaceous age. Whole-rock geochemistry using contract chemistry was obtained for 93 samples. The dataset consists of three tables in csv (comma separated values) format: (1) sample localities and lithology; (2) SHRIMP-RG (Sensitive High-Resolution Ion Microprobe-Reverse Geometry) U-Pb zircon geochronologic and trace element compositional data; (and (3) whole-rock geochemical data determined by ICP-AES-MS (Inductively Coupled Plasma Atomic Emission Spectroscopy-Mass Spectrometry) and WDXRF (Wavelength Dispersive X-ray Fluorescence).
