This collection is composed of whole-rock and EPMA tephra glass averages geochemical analyses of rocks from Alaskan volcanoes. Most of the data is from published papers, and some of it is unpublished data from AVO. It is contain analyses for approximately 13,000 samples. Nearly all of the collection is stored in a relational database; the collection is published and searchable at https://avo.alaska.edu/geochem/
