The area is part of the Circle mining district and adjacent to the Fairbanks mining district. This report includes detailed geologic, structural, stratigraphic, and geochronologic data. Based on the resulting geologic maps, field investigations, and laboratory materials analyses, the project has also generated derivative maps of geologic construction materials and geologic hazards. Purpose: The investigation of gold, and other mineral occurrences in conjunction with comprehensive geologic mapping and recently acquired geophysical data will provide a scientific basis for continued mineral exploitation that will economically benefit the region's inhabitants and the State of Alaska.

Publication_Date: 1993 Title: Interim geologic map of the Circle mining district Geospatial_Data_Presentation_Form: map Series_Information: Series_Name: Public Data File Issue_Identification: PDF 93-86 Publication_Information: Publication_Place: Fairbanks, Alaska Publisher: Alaska Division of Geological & Geophysical Surveys Other_Citation_Details: 1 sheet, scale 1:63,360 Online_Linkage: http://dx.doi.org/10.14509/1625 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Geologic data were digitized from a mylar geologic compilation.This compilation was done on a one to one scale, stable mylar of the USGS topographic base for each of the 1:63,360 scale USGS topographic bases included in the map area.Geologic data included in the compilation are the field maps and notes from this project. Surficial geological information was interpreted from false color infrared aerial photography and transferred to the basemap using a zoom transfer scope. The resulting compilation was then digitized with an average RMS error of .003 or less. The geologic interpretations presented in this report have undergone two technical reviews by geologists familiar with the subject of the report or geology of the map area. Reviewers' suggestions were incorporated into the final draft when deemed appropriate by the author. Logical_Consistency_Report: The logical consistency of the polygon, point and line files has been visually checked but not systematically verified. Some topology errors are known to exist in the polygon files. Completeness_Report: This dataset includes geospatial information about geologic units, sample locations for radiometric age dates, structural features and structural measurements. Many of the lithologic and anaylitical samples collected for this project are housed at the Alaska Geologic Materials Center (GMC). Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Location data were determined visually using topographic maps at scales of 1:63,360 and larger. Altimeters were also used. GPS technology was not used to determine locations. Instead, geologic contacts, sample, and station locations were visually hand-plotted onto stable mylar bases from the field maps. The coordinates of sample and station locations were determined with a digitizing tablet. All samples plotted on the maps are included in the various tables. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 100 Horizontal_Positional_Accuracy_Explanation: The estimated horizontal error of this dataset is +/- 100 meters. Considering the errors inherent in the USGS topographic maps, locating oneself in the field, and the digitizing method, all localities, stations, and samples are located to an accuracy of between 10 and 100 meters. Lineage: Process_Step: Process_Description: The geologic data included in this project were digitized from a mylar compilation of geologic field maps produced on USGS topo bases of the area. Map unit (polygon) locations and attributes were checked by two reviewers broadly familiar with the dominant geologic rock types in the Fairbanks area. Locations were determined visually using topographic maps at scales of 1:63,360 and 1:25,000.Geologic contacts, sample, and station locations were visually hand-plotted onto stable mylar bases from the field maps. Process_Date: 1995 Process_Step: Process_Description: This project was included in a legacy data rescue effort. The metadata and distribution files were compiled long after project completion. The original ARC coverages for this dataset were damaged and subsequently reconstructed by the GIS manager. Lineage information and attribute value information not documented in this file is unavailable. Process_Date: 2008 Process_Step: Process_Description: The layer 'realtstunion2_polygon' was added to the metadata and distribution dataset.
