This dataset contains geochemical, geochronologic, and isotopic data collected for rocks and zircons from Mountain Pass, California, USA. See accompanying Economic Geology publication described in the "Larger Work" section of this metadata file for a detailed description of this dataset.

This dataset contains geologic mapping coordinates, and geochemical, geochronologic, and isotopic data collected for shonkinite dikes and zircons from Bobcat Hills, California, USA. See accompanying G-Cubed publication described in the "Larger Work" section of this metadata file for a detailed description of this dataset.

This dataset provides geochronologic, geochemical, and isotopic data for selected igneous rock samples collected in the Lane Mountain area about 20 kilometers northeast of Barstow, California, between the years 2014 and 2021. Uranium-lead (U-Pb) zircon geochronologic and whole-rock geochemical data were obtained for 62 samples of which 28 are from Permian to Triassic plutonic rocks and dikes, 24 from Late Jurassic plutonic rocks, 6 from Late Cretaceous plutonic rocks and dikes, and 4 from Miocene volcanic rocks. Rubidium-strontium (Rb-Sr) isotopic data were obtained for 8 Permian to Triassic samples, 9 Late Jurassic samples, and 4 Late Cretaceous samples. Oxygen isotope data were obtained for 2 Permian to Triassic samples, 6 Late Jurassic samples, and 2 Late Cretaceous samples. The dataset consists of six 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 data; (3) sample ages derived from the geochronologic data; (4) whole-rock geochemical data determined by ICP-AES-MS (Inductively Coupled Plasma Atomic Emission Spectroscopy-Mass Spectrometry) and WDXRF (Wavelength Dispersive X-ray Fluorescence); (5) whole-rock Rb-Sr isotopic data measured on a solid source mass spectrometer, along with calculations of the original 87Sr/86Sr isotopic ratios based on the measured data; and (6) whole-rock oxygen isotope determinations of delta 18O.

This U.S. Geological Survey (USGS) data release provides zircon U-Pb geochronology and whole rock isotope geochemistry for drill core samples from Montana, Nebraska, Nevada and Wyoming. The drill core samples were obtained from the USGS Core Research Center in Denver, Colorado. The samples were in order to constrain the age, provenance, metamorphic history, and geochemical character of basement terranes in the United States.

This U.S. Geological Survey (USGS) data release provides whole rock major, minor, and trace element geochemical data and zircon U-Pb geochronology and trace element concentrations for samples from pre-ignimbrite volcanoes within the San Juan locus of the mid-Cenozoic Southern Rocky Mountain volcanic field, Colorado. Samples were collected in order to constrain the evolution of the pre-ignimbrite magmatic system.
