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...

The legacy thin section collection represents petrographic thin sections collected by DGGS geologists for field projects involving geologic mapping in areas of Alaska with a focus to study the potential and controls of mineral and energy resources. As part of the mapping process, rocks were collected for petrographic work to provide information for discriminating between various rock types and to write unit descriptions of the final rock types or units represented on geologic maps resulting from the field work. The collection represents 27 years or more of work and over 15,000 outcrop thin sections from all over Alaska and a wide variety of field geologists. Samples are housed in various locations within the DGGS...
