    • Appendices for GIS-Based Identification of Areas that have Resource Potential for Sediment-hosted Pb-Zn Deposits in Alaska

    Metadata Updated: December 10, 2025

    Compressed file sedPbZn_Appendices.zip contains the appendix files 2, 3, and 4 associated with U.S. Geological Survey (USGS) publication Open-File Report 2020-1147. Appendix 2 provides the scoring criteria of the Alaska Resource Data File (ARDF), listing keywords for different ARDF fields and the weighting factor for each word. Appendix 3 lists the ARDF sites with the resulting scores of the keyword searches. Appendix 4 charts out the queries used on the Geologic Map of Alaska to create different lithology datasets. The appendices are each provided as XLSX and CSV files. Also included is a CSV with the results of the scoring analysis showing for each subwatershed (HUC12) the score for each source data layer, total score, and potential and certainty classification.
