Source Data for GIS-based Identification of Areas that
have Resource Potential for Sediment-hosted Pb-Zn Deposits
in Alaska
Description
Compressed file sedPbZn_SourceData_gdb.zip contains the GIS
datasets and Python scripts used to calculate the estimated
potential and certainty that sediment-hosted Pb-Zn (lead-zinc)
deposits might be present in an area in Alaska. The statewide
datasets include: Alaska Geochemical Database (AGDB3), Alaska
Resource Data File (ARDF), lithology layers created from Alaska
Geologic Map (SIM3340), and 12-digit HUCs, subwatersheds from the
National Watershed Boundary dataset. FGDC metadata for all datasets
are included. In addition, files are included for the user to
modify the parameters of the analysis. These include two Python
scripts, 1) used to score ARDF sites for sediment-hosted Pb-Zn
potential, and 2) to evaluate each 12-digit HUC for sediment-hosted
Pb-Zn potential and certainty based on queries on AGDB3, ARDF, and
lithology. An mxd file and cartography layers are included for
viewing the data selections in ArcGIS. Other supporting documents
are included.
Compressed file sedPbZn_SourceData_shape.zip contains shapefiles
versions of all the geodatabase feature classes which are derivatives
of published datasets ARDF and SIM3340, and CSV files of the ARDF
keyword files. Other supporting documents included are: FGDC metadata
for each data source, a pdf showing the query parameters for the analysis,
and a README file.
