This map was prepared principally by the interpretation of 1:63,360-scale, false-color, infrared aerial photographs taken in 1979 and 1981 and is locally verified by ground observations during field work in 2007. 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/10.14509/22642. Purpose: The purpose of this map is to show the distribution of unconsolidated geologic deposits and related features in the northern Fairbanks mining district.

Partial funding for the geologic mapping was also provided by the U.S. Geological Survey, National Cooperative Geologic Mapping Program, under STATEMAP award number 07HQAG0076, and the State's General Fund. Richard D. Reger and Trent D. Hubbard provided very helpful suggestions that improved this map. The geologic map database was converted to GeMS, quality controlled, and then finalized by DGGS staff Wes Buchanan and Mike Hendricks. Geologic map conversion to the GeMS standard was funded by the USGS National Cooperative Geologic Mapping Program under STATEMAP award number G21AC10706, 2022, and the State of Alaska General Fund.

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 the AK GeMS geologic mapping schema specifications. Completeness_Report: This publication is part of a DGGS Report of Investigations (RI). An RI is the completed product of original research and analysis, and RIs use professional cartography and undergo rigorous peer review, editing, and revision. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Certainty in feature boundaries or location varies throughout the map. Data fields within each feature class and the accompanying orientation and location confidence lookup tables record the authors' degree of confidence in the location of applicable features.

Field notes and sediment samples were collected throughout the area for surficial investigations. Surficial mapping involved using Chapin and others (2006), Kreig and Reger (1982), Mason and Beget (1991), Rawlinson and Hickmott (1987), and Weber and Hamilton (1984) on a regular basis for checking glacial geology and general units. Observations were recorded on co-registered acetate overlays on 1:65,000-scale (nominal) color-infrared aerial photographs, and directly on 1:63,360-scale topographic base maps. Stations were located using air photos, topographic maps, and handheld GPS devices with location precision varying from approximately 3 to 15 meters. Surficial-geologic information was interpreted using 1:65,000-scale (nominal) air-photo stereopairs, and compiled using a permanent ink pen onto co-registered clear acetate overlays. Digital files of the air photos were orthorectified using OrthoMapper photogrammetric software. The co-registered acetate overlays of geologic mapping were then orthorectified using the same equations applied to the air photos. Resultant orthorectified map data were then imported into ArcGIS and heads-up digitized into a personal geodatabase with validated topology. A comprehensive bibliography is included in the accompanying report. Process_Date: 2011 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.
