Solie, D.N. Werdon, M.B. 2014 report and digital data Raw Data File RDF 2014-23 Fairbanks, Alaska, United States Alaska Division of Geological & Geophysical Surveys 4 p. http://dx.doi.org/10.14509/29141 In 2006-2007, Alaska Division of Geological & Geophysical Surveys (DGGS) geologists traversed and collected rock samples from ridges on the north side of Granite Mountain in the Mount Hayes D-3 Quadrangle to supplement existing literature with additional details about the variations in texture, lithology and orientation of the 'Granite of Granite Mountain' (map unit grgm) described by Nokleberg and others (1992). The digital data files for this report provide station locations and observations recorded in the geologists' field notes. Outcrop observations describe fine- to medium-grained granodiorite and medium- to coarse-grained tonalite units which appear to be in contact with each other on the ridges north of Granite Mountain. Mafic enclaves are common; mafic and felsic dikes transect the plutonic rocks. Slices of quartzite are either in faulted or intrusive contact within the pluton. DGGS conducted a multi-year project (from 2006 through 2010) studying the geology and geologic hazards along the Alaska Highway corridor. As part of the bedrock geologic mapping, traverses were conducted in the corridor on the north side of Granite Mountain. DGGS is publishing bedrock geologic maps of the Alaska Highway corridor farther east, from the Little Gerstle River area to the Canada border as three separate maps (Werdon and others, in press, Little Gerstle River to Dot Lake; Werdon and others, in press, Dot Lake to Tetlin Junction; Solie and others, in press, Tetlin Junction to Canada border). This report covers bedrock geologic observations between Delta Junction and Little Gerstle River, for an area not included in the map areas described above. The DGGS metadata standard extends the FGDC standard to include elements that are required to facilitate our internal data management. These elements, referred to as "layers," group and describe files that have intrinsic logical or topological relationships and correspond to subdirectories within the data distribution package. The metadata layer provides an FGDC metadata file and may include other documentation files. Attribute information for each data layer is described in this metadata file under the "Entity_and_Attribute_Information" section. Data layer contents: >border: A polygon that encompasses the geographic extent of the data observations. >Stations: A point file that provides location information, observations, symbology, and other data specific to each field observation station. >OrientationPoints: A point file that provides field station locations, symbology, and associated structure data (bedding attitudes, foliation attitudes, slip vectors measured at a point, etc.) for a subset of the records presented in the related Stations table. 2006 2007 2014 ground condition complete None planned -145.386054 -145.350872 63.847921 63.758541 ISO 19115 Topic Category geoscientificInformation Alaska Division of Geological & Geophysical Surveys Geology Granite Sample Location Structural Geology Structure Alaska Division of Geological & Geophysical Surveys Granite Mountain This report, map, and/or dataset is available directly from the State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys (see contact information below).

Field observations used in this report were made by Melanie Werdon of DGGS and visiting Nevada Bureau of Mines and Geology geologist James E. Faulds. This data release provides uninterpreted field data. The report and files were lightly reviewed by an additional geologist familiar with the subject matter. We incorporated the reviewer's suggestions into the final draft. Not applicable DGGS does not anticipate conducting additional work pertaining to the Granite Mountain study area. The horizontal position error of sample locations in this report is in the range of 6 meters. Nokleberg, W.J. Aleinikoff, J.N. Lange, I.M. Silva, S.R. Miyaoka, R.T. Schwab, C.E.

Throughout the study area geologists collected rock samples, noted outcrop descriptions, and conducted structural measurements. Nokleberg, W.J. and others, 1992 2007 Hand sample rock classification - Selected rock slab samples were stained and classified according to the estimated relative amounts of quartz, plagioclase, and alkali-feldspar. 2007 Data organization - Field observations and rock sample descriptions were compiled into a spreadsheet and imported into a ArcGIS shapefiles. To facilitate potential integration with other DGGS GIS data, the observation records were organized and attributed according to the NCGMP09 geodatabase standard. To facilitate use by the widest array of software, the files were subsequently exported from shapefile to CSV (comma delimited) format. 2014 point Universal Transverse Mercator 6 0.999600 -147 0 500000.000000 0 coordinate pair 0.000001 0.000001 meters North American Datum of 1927 Clarke 1866 6378206.4 294.9786982 rdf2014-23-border.shp A polygon that encompasses the geographic extent of the data observations.
