Geochemistry and mineralogy of the Josephine Peridotite of California and Oregon Geochemistry and mineralogy of the Josephine Peridotite of California and Oregon
This data release includes whole rock geochemical data from 33 samples and mineralogical data from 12 samples of the Josephine Peridotite in California and Oregon. Rock samples were collected in 2024 by Naomi Becker and Katie Tognotti. Whole rock geochemistry data were analyzed by contract lab through the U.S. Geological Survey's Mineral Resources Program at the Geology, Geophysics, and
Geochemical data, thin section images, and modal mineralogy of selected bedrock samples from the Halifax County complex, North Carolina Geochemical data, thin section images, and modal mineralogy of selected bedrock samples from the Halifax County complex, North Carolina
This data release contains geochemical data, thin section images, and modal mineralogy from bedrock samples of the Halifax County complex in North Carolina. The geochemical data comprise whole-rock major oxide and trace element abundances in 11 samples. Modal mineralogy was obtained by powder X-ray diffraction and the Rietveld method of the same 11 samples. Pairs of thin section images...
Visible and Near Infrared (VNIR) and Short Wavelength Infrared (SWIR) Spectra of Select Altered Mafic and Ultramafic Rock Samples from the Josephine Peridotite in CA and OR, the Yukon-Tanana region in Alaska, and from the Southern Appalachians in VA, NC, Visible and Near Infrared (VNIR) and Short Wavelength Infrared (SWIR) Spectra of Select Altered Mafic and Ultramafic Rock Samples from the Josephine Peridotite in CA and OR, the Yukon-Tanana region in Alaska, and from the Southern Appalachians in VA, NC,
These data are laboratory reflectance measurements conducted on a suite of altered mafic and ultramafic rocks. Visible-Near InfraRed (VNIR) and Short-Wave InfraRed (SWIR) reflectance measurements were made (~0.4 – 2.5 microns) using an artificial light source connected to an Analytical Spectral Devices (ASD) spectrometer. Spectra from a total of 91 samples were measured and analyzed...
Geochemistry of mafic and ultramafic rocks in the Eastern Blue Ridge of Virginia and North Carolina (ver. 2.0, September 2025) Geochemistry of mafic and ultramafic rocks in the Eastern Blue Ridge of Virginia and North Carolina (ver. 2.0, September 2025)
This data release includes whole rock (WR) geochemical data for 92 samples. Whole rock geochemistry data were analyzed at Actlabs in Ancaster, Ontario, Canada. Rock samples were collected from 2020 to 2024 by Naomi Becker, Arthur Merschat, Mark Carter, and Kadie Steup. The whole rock geochemistry data characterize the composition of mafic and ultramafic (MUM) rocks in the Eastern Blue...
