Whole Rock Major and Trace Element Chemistry for Igneous, Sedimentary and Metamorphic Rocks from Southcentral Alaska
This dataset consists of one table containing whole-rock geochemistry data for 748 rocks from southcentral Alaska. All materials in the present study were analyzed by ALS Global between 2014 and 2022 using a range of different techniques, so multiple unique entries for a given element relate to different analytical methods or preparations, as detailed in accompanying metadata, and summarized in a supporting Data Dictionary tabular data file. Most samples analyzed in the present study were collected by U.S. Geological Society researchers between 2014 and 2017. The data set also includes new analyses of legacy samples collected by the U.S. Geological Society, many of which were previously analyzed using a range of different analytical methods, often at lower detection limits and using partial digestion methods. The original geochemical data and analytical method information for those analyses are compiled in Granitto et al. (2024). Sample location coordinates are given in decimal degrees relative to the World Geodetic System (WGS) 1984.
