Collection of geochemical data from Alaska (AVO) 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 Most of the data is from published papers, and some of it is unpublished data from AVO.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/ Categories: Physical Item; Types: Collection, Map Service, OGC WFS Layer, OGC WMS Layer, OGC WMS Service; Tags: Chemistry, Geochemical Data, Geochemistry, Geological Collection, Tephra, All tags... Volcanic, Volcanic Rocks, Volcanoes, Volcanology, Fewer tags Collection of samples from Alaska (AVO) This collection is composed of hand samples, thin sections, geochemical pulps and crushed splits of rock collected by the Alaska Volcano Observatory (AVO), a joint program of the United States Geological Survey (USGS), the Geophysical Institute of the University of Alaska Fairbanks (UAFGI), and the Alaska Division of Geological and Geophysical Surveys (ADGGS). It includes rocks from AVO field projects as well as samples collected by AVO-supported graduate students as part of our efforts to better understand eruptive processes and mitigate eruption hazards. It is estimated that there are about 30,000 samples in this collection. The Alaska Division of Geological and Geophysical Surveys division of AVO has no direct...
