The report describes the geologic setting, structural geology, earthquake potential, economic geology and the description of bedrock units. This project and resulting report, map and geospatial data are intended to provide an updated surficial and bedrock geologic map of the Fairbanks Mining District at 1:63,360 scale that depicts construction material availability, geologic hazards, mineral potential, and new geologic information. The Fairbanks mining district was originally mapped 15 years ago by Metz (1982), Robinson (1982), and Bundtzen (1982). The final map product was not published until 1990 (Robinson and others, 1990). The earlier work did not include surficial coverage and due to extensive cover the bedrock geology was based on only a few percent rock exposure. 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 geologic unit code set file "PDF1996-16_codeset.pdf". Layers include: >fbxcline_arc anticline and syncline traces of axial planes >fbxflt_arc fault location traces and types >fbxgeo_arc geologic units (arc) >fbxgeo_polygon geologic units (polygon) >fbxgeou_arc subsurface data extrapolated from geophysics data >fbxsamp_point points of sample localities (Sheet 2) >fbxstrdip_point point attribute table that displays strike and dip information >fbxstsym_point points for the strike, dip, and plunge of bedding planes, foliation, and various lineaments >pingos_point points of pingo localities >skpnts_point points of skarn localities 199507 199607 publication date complete none planned -148.442995 -146.828401 65.208488 64.744542 64.75 -148.42 64.75 -147.62 64.98 -147.00 65.13 -146.83 65.21 -146.83 65.21 -147.22 65.00 -147.94 64.98 -148.06 64.97 -148.42 64.75 -148.42 ISO 19115 Topic Category geoscientificInformation none Alluvial Deposits Colluvial Deposits Eolian Geology Mining STATEMAP Project none Alaska, State of Fairbanks Fairbanks Creek Fairbanks Mining District none Birch Creek Schist Birch Hill Sequence Chatanika Terrane Chena River Sequence Fairbanks Schist Musk Ox Sequence none Cenozoic Cretaceous Devonian Holocene Late Devonian Mesozoic Middle Devonian Paleozoic Permian Pleistocene Proterozoic Quaternary Tertiary This report, map, and/or data set are available directly from the State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys (see contact information below).

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 as well as data from other sources as noted in the "Sources Cited" section. Polygon topology present and clean on appropriate data. Other data are line, point, or annotation data and do not require topologic relationships. Chain-node topology present. This dataset includes geospatial information about geologic units, sample locations, structural features, structural measurements, pingo locations, and skarn locations. 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. 100 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. Thommen TM altimeters were frequently used and calibrated daily. 6 The estimated horizontal error of this dataset is +/- 6 meters, based upon the inherent instrument errors of the Thommen TM altimeter.

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. 1996 Universal Transverse Mercator 6 0.999600 -147.000 0.0 500000 0 coordinate pair 0.000128 0.000128 meters fbxgeo_arc Universal Transverse Mercator 6 0.999600 -147.000 0.0 500000 0 coordinate pair 0.000128 0.000128 meters fbxgeo_polygon Universal Transverse Mercator 6 0.999600 -147.000 0.0 500000 0 coordinate pair 0.000016 0.000016 meters fbxgeou_arc Universal Transverse Mercator 6 0.999600 -147.000 0.0 500000 0 coordinate pair 0.000128 0.000128 meters fbxflt_arc Universal Transverse Mercator 6 0.999600 -147.000 0.0 500000 0 coordinate pair 0.000128 0.000128 meters fbxcline_arc Universal Transverse Mercator 6 0.999600 -147.000 0.0 500000 0 coordinate pair 0.000128 0.000128 meters fbxstsym_arc Universal Transverse Mercator 6 0.999600 -147.000 0.0 500000 0 coordinate pair 0.000128 0.000128 meters fbxstrdip_point Universal Transverse Mercator 6 0.999600 -147.000 0.0 500000 0 coordinate pair 0.000064 0.000064 meters pingos_point Universal Transverse Mercator 6 0.999600 -147.000 0.0 500000 0 coordinate pair 0.000032 0.000032 meters skpnts_point Universal Transverse Mercator 6 0.999600 -147.000 0.0 500000 0 coordinate pair 0.000128 0.000128 meters fbxsamp_point D_Clarke_1866 Clarke 1866 6378206.4 294.978698 fbxgeo_arc.shp Object type is vector, there are 3989 rows associated with this entity, and the entity values refer to geologic map unit contacts.
