Summary

This dataset contains digital data that were used for the creation of a geologic map shown in Figure 3 in USGS SIR 2017-5150; Postglacial Eruptive History and Geochemistry of Semisopochnoi Volcano, Western Aleutian Islands, Alaska by Coombs, M.L. and others. The map shows the generalized geology of the island and the locations of stations occupied during field work conducted in the summer of 2005. The data are based on mapping completed during the field work, high-resolution digital imagery, and geochemical and radiometric analyses of rock and soil samples.

Purpose

This dataset contains digital data that were used for the creation of a geologic map shown in Figure 3 in USGS SIR 2017-5150. The data model the geology of Semisopochnoi Island, Alaska as of 2005. The map was used in the publication to provide context for a discussion of the geologic setting, geologic history, and volcanic hazard of the area. The data are being released pursuant to the USGS Public Access Plan, titled Public Access to Results of Federally Funded Research at the U.S. Geological Survey: Scholarly Publications and Digital Data (https://www2.usgs.gov/quality_integrity/open_access/downloads/USGS-PublicAccessPlan-APPROVED-v1.03.pdf).
