This data release contains the analytical results and the evaluated source data files 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. The packages of files available for download are: 1. The results in geodatabase format are in SedPbZn_Results_gdb.zip. The analytical results for sediment-hosted Pb-Zn deposits are in a polygon feature class which contains the points scored for each source data layer query, the accumulative score, and a designation for high, medium, or low potential and high, medium, or low certainty for sediment-hosted Pb-Zn deposits for each HUC. The data is described by FGDC metadata. An mxd file, layer file, and cartographic feature classes are provided for display of the results in ArcMap. Files sedPbZn_scoring_tables.pdf (list of the scoring parameters for the analysis) and sedPbZn_Results_gdb_README.txt (description of the files in this download package) are included. 2. The results in shapefile format are in SedPbZn_Results_shape.zip. The analytical results for sediment-hosted Pb-Zn deposits are in a polygon feature class which contains the points scored for each source data layer query, the accumulative score, and designation for high, medium, or low potential and high, medium, or low certainty for sediment-hosted Pb-Zn deposits for each HUC. The results are also provided as a CSV file. The data is described by FGDC metadata. Files sedPbZn_scoring_tables.pdf (list of the scoring parameters for the analysis) and sedPbZn_Results_shape_README.txt (description of the files in this download package) are included. 3. The source data in geodatabase format are in SedPbZn_SourceData_gdb.zip. Data layers include AGDB3, ARDF, lithology from SIM3340, and HUC subwatersheds, with FGDC metadata. An mxd file and cartographic feature classes are provided for display of the source data in ArcMap. Also included are two python scripts 1) to score the ARDF records based on the presence of certain keywords, and 2) to evaluate the ARDF, AGDB3, and lithology layers for the potential for sediment-hosted Pb-Zn deposits within subwatershed polygons. Users may modify the scripts to design their own analyses. Files sedPbZn_scoring_table.pdf (list of the scoring parameters for the analysis) and sedPbZn_sourcedata_gdb_README.txt (description of the files in this download package) are included. 4. The source data in shapefile and CSV format are in SedPbZn_SourceData_shape.zip. Data layers include ARDF and lithology from SIM3340, and HUC subwatersheds, with FGDC metadata. The ARDF keyword tables available in the geodatabase package are presented here as CSV files. All data files are described with the FGDC metadata. Files sedPb_Zn_scoring_table.pdf (list of the scoring parameters for the analysis) and sedPbZn_sourcedata_shapefile_README.txt (description of the files in this download package) are included. 5. Appendices 2, 3 and 4, which are cited by the larger work OFR2020-1147. Files are presented in XLSX and CSV formats.
