In the summers of 1982 through 1985, the U.S. Geological Survey conducted geologic studies Bureau of Land Management Wilderness Study Areas on the Kern Plateau as well as the U.S. Forest Service South Sierra Wilderness and South Sierra Roadless Area. These study areas are underlain mostly by granitic rocks of the Sierra Nevada batholith. In support of geologic mapping and mineral-resource assessment, 74 samples were analyzed for major-element oxides (SiO2, Al2O3, Fe Total, MgO, CaO, Na2O, K2O, TiO2, P2O5, and MnO) by X-ray fluorescence (XRF). This table gives the results of those analyses.
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
