    Davidof volcano samples and analyses

    Metadata Updated: November 3, 2023

    Davidof volcano samples and analyses, Raw Data File 2023-22, provides calculations and analytical results from samples collected in the western Aleutian Islands in 2021 by Alaska Volcano Observatory (AVO) geologists Hannah Dietterich and Matt Loewen. The primary target of this sampling was Davidof volcano, a partially submerged 5 km-diameter caldera located in the Rat Islands. Subaerial exposures include Davidof, Khvostof, Lopy, and Pyramid islands. The only prior published work on Davidof volcano was part of the U.S. Geological Survey's post World War II geologic reconnaissance of the Aleutian Islands (Nelson and others, 1959). Nelson and others (1959) only indicate two samples from Davidof volcano that were analyzed petrographically, but prior to this data release no quantitative data for Davidof volcano have been available. This report also includes samples collected during 2021 from the western shore of Little Sitkin Volcano, as well as new electron microprobe analyses from samples previously collected in 2005 and 2015 from Little Sitkin Volcano and 2015 from Segula Volcano. Data associated with this report are archived in the Geologic Database of Information on Volcanoes in Alaska (GeoDIVA; Cameron and others, 2022, doi.org/10.14509/geodiva. This report is released as a Raw Data File with an open end-user license. The data are available from the DGGS website: http://doi.org/10.14509/31084.
