Summary

Compressed file SedPbZn_Results_gdb.zip contains the analytical results of a geospatial analysis for identifying areas in Alaska that may have potential for sediment-hosted Pb-Zn (lead-zinc) deposits. The spatial analysis is based on queries of statewide source datasets Alaska Geochemical Database (AGDB3), Alaska Resource Data File (ARDF), and Alaska Geologic Map (SIM3340) within areas defined by 12-digit HUCs (subwatersheds) from the National Watershed Boundary dataset. An ArcMap mxd file, layer file, and geodatabase with cartographic layers is provided for users to view the analytical results in ArcMap. Additional files include FGDC metadata, a pdf showing the query parameters for the analysis, and a README file. Compressed file [...]

Purpose

The purpose of this spatial analysis is to examine and understand the distribution of sediment-hosted Pb-Zn deposits in Alaska. This GIS-based analysis uses published datasets of geochemistry, mineral resource data, and geology to identify areas that may be prospective for this type of mineral deposit. The analysis also identifies areas with limited data, which could be used to highlight areas needing additional studies. A full description of the analysis process and results is published in Kelley and others, 2020.
