Data and analysis for GIS-based identification of areas that have resource potential for sediment-hosted Pb-Zn deposits in Alaska
This data release contains the analytical results of a spatial analyses for the resource potential of sediment-hosted Pb-Zn (lead-zinc) deposits in the state of Alaska. Sediment-hosted Pb-Zn deposits in Alaska include those contained in carbonate rock and in clastic-dominated sequences. The geographic information system (GIS) analysis queried three publicly available statewide datasets in areas defined by 12-digit HUCs (subwatershed) boundaries from the National Watershed Boundary dataset. The source data layers evaluated are Alaska Geochemical Database, Alaska Resource Data File, and Geologic Map of Alaska. The results and analyzed datasets are provided in geodatabase and shapefile formats and each data layer is described with FGDC-style metadata. Also provided are files for displaying the data and results in ArcMap, python scripts that may be edited for modifying the analysis parameters, and supplementary files. The digital files are organized in three groups, Results, Source Data, and Appendices. The approach and explanation of results are presented in Kelley, K.D., Graham, G.E., Labay, K.A., and Shew, N.B., 2020, GIS-based identification of areas that have resource potential for sediment-hosted Pb-Zn deposits in Alaska: U.S. Geological Survey Open-File Report 2020-1147.

GIS-based identification of areas that have resource potential for sediment-hosted Pb-Zn deposits in Alaska
A state-wide Geographic Information System analysis was conducted to assess prospectivity for lead (Pb) and zinc (Zn) in sediment-hosted deposits in Alaska. The datasets that were utilized include publicly available geospatial datasets of lithologic, geochemical, and mineral occurrence data. Key characteristics of Pb-Zn deposits were identified in available datasets and scored with respect to relaAuthorsKaren D. Kelley, Garth E. Graham, Keith A. Labay, Nora B. Shew - Connect
