Publication_Date: 1994 Title: Progress report on the geology and mineral resources of the Nome mining district, Alaska Geospatial_Data_Presentation_Form: geodatabase Series_Information: Series_Name: Public Data File Issue_Identification: PDF 94-39 Publication_Information: Publication_Place: Fairbanks, Alaska, United States Publisher: Alaska Division of Geological & Geophysical Surveys Other_Citation_Details: 21 p., 2 sheets, scale 1:63,360 Online_Linkage: https://doi.org/10.14509/1665 Description: Abstract: Public Data File 94-39, Progress report on the geology and mineral resources of the Nome mining district, Alaska, presents 1:63,360-scale reconnaissance bedrock and surficial geologic mapping of about 1,900 square kilometers (590 square miles) in the Nome mining district of western Alaska. The Nome mining district is an area of intensely metamorphosed schists. Four types of metallic mineral resources were identified in the study area: (1) gold-polymetallic- quartz-carbonate veins cutting pelitic and mafic schists and carbonates believed to have formed as a result of regional metamorphism; (2) stratiform, massive sulfide-barite deposits associated with felsic metavolcanic schist and metafelsite centers; (3) massive sulfide-iron deposits hosted in carbonate-dominated terranes and of uncertain origin; and (4) heavy mineral placer deposits that have accounted for almost all of the metallic mineral production in the study area. The dataset contains geologic, structural, stratigraphic, and geochronologic data organized according to the GeMS and AK GeMS mapping schemas. The complete report, geodatabase, and ESRI fonts and style files are available from the DGGS website: http://doi.org/10.14509/1665. Purpose: The Nome mining district geologic mapping project was undertaken as a result of a Capital Improvements Project appropriation passed by the 1993 Alaska Legislature to begin detailed geological and mineral resource investigations of Alaskan mining districts using airborne, multispectral geophysical surveys, and 1:63,360-scale geological mapping. Supplemental_Information: This geodatabase is organized according to the AK GeMS mapping schema Hendricks, M.D., Ekberg, P.G., Athey, J.E., Wyatt, W.C., Willingham, A.L., and Naibert, T.J., 2021, AK GeMS data dictionary: A description of the Alaska geologic mapping schema: Alaska Division of Geological & Geophysical Surveys Miscellaneous Publication 170, 10 p. https://doi.org/10.14509/30669.

Data_Set_Credit: The map authors thank Chuck Hawley and Ms. Cindy Buxton of Kennecott Exploration Inc. for sharing their extensive knowledge of the geology of the Gold Hill and Aurora Creek areas. Allison Till (U.S. Geological Survey) spent two days with the mapping crew during the 1993 field season and demonstrated a defendable, metamorphic lithostratigraphy for the Nome Group in the western Solomon Quadrangle. Tom Sparks of Bering Straits Native Corporation and Irene Anderson of Sitnausuk Corporation helped secure and provide logistical services during our studies. Joe Fisher kindly allowed access to Alaska Gold Company lands in the Nome district. This map was converted to GeMS or digitized into GeMS by Lars Arneson of Kinney Engineering, LCC., quality controlled, and then finalized by DGGS staff (Chris Wyatt and Mike Hendricks). Geologic map conversion to the GeMS standard was funded by the USGS National Geological and Geophysical Data Preservation Program under award number G21AP10329 and the State of Alaska General Fund. The views and conclusions contained in this document are those of the authors and should not be interpreted as necessarily representing the official policies, either expressed or implied, of the U.S. Government. Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Attribute fields within each feature class are populated using the map symbology and corresponding applicable values from the GeMS and AK GeMS specifications. When known, certainty in attribute interpretation is indicated in the relevant fields. Attribute accuracy varies throughout the map and is scale-dependent. Logical_Consistency_Report: All polygon features were topologically validated according to specifications of the AK GeMS geologic mapping schema. Completeness_Report: This publication is a DGGS Public Data File (PDF). The objective of the PDF series, published from 1983 through 1999, was to make project and field data available to the public as soon as possible. PDFs were not reviewed or edited. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: This data release provides legacy geospatial data converted to the GeMS and AK GeMS specifications. The data compilers used map symbology to determine positional accuracy. The data pairs descriptive fields within each feature class with location confidence lookup tables to record the originating authors' degree of confidence in the location of features. When location accuracy values are unavailable, users must infer positional accuracy based on standard geologic mapping practices of the investigation era. Certainty in feature boundaries or location varies throughout the map. Lineage: Source_Information: Source_Citation: Citation_Information: Originator: Ekberg, P.G.

Field notes, orientation measurements, and rock samples were compiled and collected throughout the map area. Mappers recorded observations on 1:50,000- and 1:63,360-scale airphotos and topographic base maps. Map interpretation relies on outcrop, subcrop, and float observations, major oxide, sulfur isotope, and trace element analyses. The conceptual framework for the regional geology incorporates key ideas from preexisting literature with new data and interpretations developed from field mapping and analytical findings. The accompanying map or report provides a comprehensive bibliographic reference list of prior work used to identify and delineate rock units and structural elements. Process_Date: 1994 Process_Step: Process_Description: GIS analysis and digital cartography - This data distribution package's geologic and geographic features were organized and attributed according to the AK GeMS geologic mapping schema. The data were programmatically transformed to provide download options in three formats: (1) an AK GeMS data package that includes the complete AK GeMS database and associated files, (2) a GeMS data package that is a conversion of the AK GeMS database into the base GeMS standard published by the USGS, and (3) a shapefile data package that includes two simple shapefile representations of the data.
