Publication_Date: 1998 Title: Interpretive geologic bedrock map of the Tanana A-1 and A-2 quadrangles, central Alaska Geospatial_Data_Presentation_Form: geodatabase Series_Information: Series_Name: Public Data File Issue_Identification: PDF 98-37B v. 1.1 Publication_Information: Publication_Place: Fairbanks, Alaska, United States Publisher: Alaska Division of Geological & Geophysical Surveys Other_Citation_Details: 17 p., 1 sheet, scale 1:63,360 Online_Linkage: https://doi.org/10.14509/1864 Description: Abstract: Public Data File 98-37B v. 1.1, Interpretive geologic bedrock map of the Tanana A-1 and A-2 quadrangles, central Alaska, provides detailed (1:63,360-scale) geologic mapping of portions of U.S. Geological Survey Tanana A-1 and A-2 quadrangles. The map area is part of the Yukon-Tanana Upland physiographic province, the Manley Hot Springs-Tofty mining districts, and adjacent to the Rampart mining district to the south. This geologic map data release includes detailed geologic, structural, stratigraphic, and geochronologic information. The complete report, geodatabase, and ESRI fonts and style files are available from the DGGS website: http://doi.org/10.14509/1864. Purpose: The Tanana A-1 and A-2 Quadrangles lie between the villages of Rampart, on the Yukon River, and Manley Hot Springs, at the terminus of the Elliott Highway. At the time the report was published, the area towns were not part of any municipal or local governmental jurisdiction. The investigation of gold, tin, and other mineral occurrences in conjunction with comprehensive geologic mapping and recently-acquired geophysical data provide a scientific basis for expanded mineral exploration and development that can lead to the economic growth and the creation of new jobs needed by the Rampart-Manley-Tofty region's inhabitants and the State of Alaska. These objectives are consistent with the statewide goals and priorities articulated for the Department of Natural Resources by Alaska's Governor in his Executive Budget Summary for Fiscal Year 1997.

Attribute fields within each feature class are populated using 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. To record the originating authors' degree of confidence in the location of features, the data include descriptive fields within each feature class and accompanying orientation and location confidence lookup tables. When location accuracy values are unavailable, users must infer positional accuracy based on standard geologic mapping practices of the investigation era. Field stations were located using hand-held GPS units, however for fieldwork conducted before 2000, Selective Availability limited location accuracy of the coordinates to roughly 100 meters. Certainty in feature boundaries or location varies throughout the map. Lineage: Source_Information: Source_Citation: Citation_Information: Originator: Burns, L.E. Originator: Graham, G.R.C.

Geologists observed details about the variations in texture, lithology, and orientation of the map units, collected rock samples, noted outcrop descriptions, and conducted structural measurements. Bedrock mappers recorded observations on 1:50,000 and 1:63,360-scale topographic base maps and field stations were located using hand held GPS units. Field observations were integrated with existing literature and geophysical survey data.

Source_Used_Citation_Abbreviation: Liss, S.A. and others, 1998 Process_Date: 1998 Process_Step: Process_Description: Geologic map compilation - The geologic data were digitized from a mylar compilation of geologic field maps produced on USGS topo bases of the area. Contacts and other geologic features were determined visually using topographic maps at scales of 1:63,360 and 1:25,000, field station notes, and GPS location data. Geologic features were visually hand-plotted onto stable mylar bases from the field maps and then digitally compiled and plotted using ArcInfo software. The map and report received technical review and editing by several scientists familiar with the subject matter. The authors incorporated the reviewers' suggestions into the final draft when deemed appropriate. Process_Date: 1998 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 then 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.
