The area is part of the 100-year old Fortymile mining district and is located in eastern Alaska near the Alaska-Yukon border. This geologic map was produced by merging a bedrock geologic map and a surficial geologic map of the Eagle A-2 Quadrangle and based upon results from field investigations by DGGS in 1999 and 2000, which were part of a three-year mapping program to provide geologic ground truth for airborne geophysical surveys flown by DGGS in the Fortymile mining district during 1998. Purpose: This project, resulting map, geospatial data are intended to provide a geologic map and a geologic interpretation of the Fortymile mining district at 1:63,360 scale. Previous published 1:63,360 scale geologic maps of this area have been reconnaissance-level maps or only covered portions of the quadrangle. Mapping at 1:63,360 scale (or more detailed) is needed to identify critical geologic features that may relate to more regional structures or geologic units. These detailed observations are also critical to test or use in tectonic models. This map also provides a geologic base in which to interpret geochemical results from the concurrent DGGS rock sampling program. Supplemental_Information: The layers listed below are present as ArcGIS shape files. Attribute information for the following layers (entities) is included in this metadata file under the "Entity_and_Attribute_Information" section. Each layer is listed and described in detail under its own heading starting "Entity_Type_Label." Basic unit information is also included in the unit code set file "PIR2001-3_codeset.pdf." Layers include: >fmarpoints locations of Ar/Ar analyses samples >fmcompcont geologic bedrock contacts under surficial geology >fmcompdikes dike locations (arc) >fmcompfolds fold axis (anticline or syncline) traces >fmcompgeo comprehensive geologic units >fmdikepoints dike locations (point) >fmfaults_arc fault contacts (arc) >fmfaults_point fault symbols (point) >fmfoldsym symbols for folds, anticlines, synclines, and bedding features >fmkyanitepts locations where the mineral kyanite was found >fmpingos pingo locations >fmstrike lineaments and bedding planes Time_Period_of_Content: Time_Period_Information: Range_of_Dates/Times: Beginning_Date: 1999 Ending_Date: 2001 Currentness_Reference: publication date Status: Progress: Complete Maintenance_and_Update_Frequency: none planned Spatial_Domain: Bounding_Coordinates: West_Bounding_Coordinate: -142.00902346 East_Bounding_Coordinate: -141.49552824 North_Bounding_Coordinate: 64.25256429 South_Bounding_Coordinate: 63.9974188 Keywords: Theme: Theme_Keyword_Thesaurus: ISO 19115 Topic Category Theme_Keyword: geoscientificInformation Theme: Theme_Keyword_Thesaurus: none Theme_Keyword: Augen Gneiss Theme_Keyword: Geology Theme_Keyword: Mining Theme_Keyword: Plutons Theme_Keyword: STATEMAP Project Theme_Keyword: Terrace Place: Place_Keyword_Thesaurus: none Place_Keyword: Alaska, State of Place_Keyword: Fortymile Mining District Place_Keyword: Eagle Quadrangle Place_Keyword: Chicken Stratum: Stratum_Keyword_Thesaurus: none Stratum_Keyword: Chicken Metamorphic Complex Stratum_Keyword: Chicken Pluton Stratum_Keyword: Fortymile River Assemblage Stratum_Keyword: Napoleon Creek Pluton Stratum_Keyword: Taylor Mountain Batholith Stratum_Keyword: Walker Fork Pluton Temporal: Temporal_Keyword_Thesaurus: none Temporal_Keyword: Holocene Temporal_Keyword: Pleistocene Temporal_Keyword: Quaternary Temporal_Keyword: Tertiary Temporal_Keyword: Cenozoic Temporal_Keyword: Cretaceous Temporal_Keyword: Mesozoic Temporal_Keyword: Jurassic Temporal_Keyword: Triassic Temporal_Keyword: Paleozoic Temporal_Keyword: Permian Temporal_Keyword: Pennsylvanian Temporal_Keyword: Mississippian Temporal_Keyword: Devonian Temporal_Keyword: Precambrian Access_Constraints: This report, map, and/or dataset are available directly from the State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys (see contact information below).

This compilation for the surficial-geologic information was done on a paper map of the USGS topographic base for each of the 1:63,360 scale USGS topographic bases included in the map area. Bedrock geologic information was compiled on stable mylar with abundant control points at 1:50,000 scale that was scanned and co-registered in ArcView GIS Version 3.1? to a 1:63,360-scale USGS topographic base. Geologic data included in the compilation are the field maps and notes from this project as well as data from other sources as noted in the "Sources Cited" section. Logical_Consistency_Report: Polygon topology present. Polygon topology present on appropriate data; others are line, point, or annotation data and do not require topologic relationships. Completeness_Report: This data set includes geospatial information about geologic units, age and field sample locations, structural features, structural measurements, pingo and dike locations. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Surficial mappers recorded observations on 1:50,000 scale (nominal) color-infrared aerial photographs and 1:63,360 scale topographic base maps. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 15 Horizontal_Positional_Accuracy_Explanation: Stations located using air photos and hand held GPS devices with location precision varying from +/-3 to 15 meters. This error results from items such as error in satellite positions, mathematical error introduced by the formulas used by the GPS unit for calculating position, and errors caused by narrow satellite alignments. Estimated position error is a value determined by the GPS manufacturer for the calculation and geometric error as a whole. "Selective availability," a deliberate degradation of GPS data managed by the U.S. government that induces an additional error of approximately 100 meters to a GPS location, was not in effect during this project's 2000 and 2001 field work.

Source_Used_Citation_Abbreviation: Yeend, 1996 Process_Date: 2000 Process_Step: Process_Description: Laboratory data compilation- Laboratory analyses were performed on rock samples collected during the fieldwork process step from July 1999 intermittently through April 2001. Published geochemical and age results are found in Szumigala and others (2000) and Werdon and others (2000). Unpublished laboratory results include petrographic work on thin sections and modal analysis of rock slabs stained for plagioclase and potassium feldspar. Results from major oxide and trace element geochemistry of igneous and metamorphic rocks were used to calculate CIPW Norms for use in classifying rocks according to established petrologic nomenclature. Thin sections produced by this study are currently stored at the DGGS office in Fairbanks, Alaska. Rock samples, including geochemical sample pulps and rock hand samples from most field stations, are currently stored at the DGGS office in Fairbanks. Final storage for most rock samples generated by this study will be at the DGGS Geologic Materials Center (GMC) in Eagle River, Alaska.

Process_Date: 2000 Process_Step: Process_Description: Geologic map compilation- Bedrock geologic map was compiled using field notes from fieldwork process step (above), analytical results from laboratory data compilation process step (above), and all known geologic data from previous work in quadrangle. The main sources of existing data include Foster (1969), Newberry and others (1988), DGGS and others (1999), Szumigala and others (2000), and Werdon and others (2000). Data was compiled on multiple layers of stable mylar at 1:50,000 scale, with some information plotted at 1:24,000 scale for more detail and later transferred to 1:50,000 scale mylar layers. Relevant information from all mylar layers was compiled onto one stable mylar sheet with abundant control points. The compilation mylar was scanned by a large-format scanner and saved as a TIFF image. The TIFF image was imported into ArcView GIS Version 3.1? distributed by ESRI, Inc., then co-registered to a georeferenced 1:63,360-scale USGS topographic base. Geologic contacts and unit polygons were digitized on-screen in ArcView.Station-specific information such as structural measurements, location of age samples, and location of dikes too small to be mappable features were imported into ArcView from a Microsoft Access database using GPS locations. Surficial geology was plotted on mylar-covered air photos and transferred to stable mylar with a 1:63,360 scale USGS topographic base. Surficial geology was digitized and imported into Arc/Info version 7.0.4 for coding of shapes and lines. Bedrock and surficial geology sets were merged and "windows" were made within surficial units to allow exposure of outcrop and "rubcrop" areas on comprehensive geologic map.
