Résumé du livre
Geologists from the Alaska Division of Geological & Geophysical Surveys spent 10 days between June 19 and June 28 doing preliminary geologic reconnaissance of the Tok River area in preparation for a proposed 2016 mapping project. During the course of this reconnaissance, the field crew collected additional geologic observations and geochemical data for several mineral occurrences and one inactive placer mine. This report summarizes these observations and will be used to update the Alaska Resource Data File (ARDF) records for the project area. The ARDF is a mineral occurrence database maintained by the U.S. Geological Survey; it is available online at: http://ardf.wr.usgs.gov/.
