Description
Source compositions of large tephra-production eruptions in Alaska, Raw Data File 2023-26, provides new in situ geochemical analyses from previously collected samples originally utilized/interpreted in the Geochemistry, Geophysics, Geosystems publication "Probabilistic source classification of large tephra producing eruptions using supervised machine learning: An example from the Alaska-Aleutian arc" (Lubbers, Loewen, and others, 2023). The samples and analyses comprise 31 eruptions from 16 Alaska volcanoes. All samples have been archived in the Geologic Database of Information on Volcanoes in Alaska (GeoDIVA; Cameron and others, 2022, doi.org/10.14509/geodiva). They are available from the DGGS website: http://doi.org/10.14509/31091.
