Kline, J.T. Pinney, D.S. 1997 map and vector digital data Report of Investigations RI 97-14B Fairbanks, AK, USA State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys 1 sheet, scale 1:125,000 http://www.dggs.dnr.state.ak.us/pubs/pubs?reqtype=citation&ID=2550 This map illustrates the potential near-surface sources of various geologic materials that may be useful for construction. Field observations indicate that each geologic unit has a definite composition or range of composition wherever that unit is found. Therefore, the presence of materials is interpreted from the distribution of geologic units on the geologic map of this quadrangle. This map is generalized and is not intended to show exact locations of specific materials. The map also addresses some of the principle geologic hazards that may be associated with the deposits based upon their general physical properties and conditions that are characteristic of their depositional environment. The purpose of this map is to indicate general areas that deserve consideration for certain materials and to eliminate other general areas from consideration for these materials. Local variations are common, especially near unit boundaries. 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 "RI1997-14_codeset.pdf." Layers include: >mcgmat_arc materials units (arc) >mcgmat_poly materials units (polygon) >faultzone_arc indicates location of the Denali-Farewell fault system (arc) >faultzone_poly indicates location of the Denali-Farewell fault system (polygon) 19800701 19970630 publication date complete none planned -154.551058 -152.999998 63.007954 61.991851 ISO 19115 Topic Category geoscientificInformation none Alluvial Deposits Colluvial Deposits Eolian Geologic Hazards Geologic Materials Geology Glacial Deposits none Alaska, State of McGrath none Denali-Farewell Fault Dillinger Terrane Farewell Terrane Kahiltna Terrane McKinley Terrane Middle Fork Plutonic Complex Mystic Terrane Pingston Terrane Post River Pluton Veleska Lake Volcanic Complex Yukon-Tanana Terrane none Cambrian Carboniferous Cenozoic Cretaceous Devonian Early Devonian Early Jurassic Early Silurian Jurassic Late Devonian Late Permian Late Silurian Mesozoic Middle Devonian Ordovician Paleozoic Permian Proterozoic Quaternary Silurian Tertiary Triassic 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).

Gilbert, W.G. 1997 tabular digital data, map, vector digital data Report of Investigations RI 97-14A Fairbanks, Alaska - USA State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys http://www.dggs.dnr.state.ak.us/pubs/pubs?reqtype=citation&ID=2549 Data for geologic layers was digitized off of a mylar geologic compilation. This compilation was done on a stable mylar of the USGS topographic base for the McGrath Quadrangle, Alaska that was photographically enlarged to 1:125,000. (Topographic base compiled in 1965, revised in 1978, 1980, and 1982.) 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 coverages. Other coverages are line, point, or annotation coverages and do not require topologic relationships. Chain-node topology present. This data set includes coverages that contain information about materials units and fault system location. Location data were determined visually using topographic maps at scales of 1:63,360 and 1:40,000 scale topographic maps using USGS map bases. Some stations were plotted on 1:63,360 scale Infra-Red and 1:40,000 scale black and white air photos during mapping. Because location information was acquired during the time period 1980-1992, 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 and in some instances, air photos. The lists of samples were visually checked against the lists of analyzed samples returned from the laboratories. 100 The estimated horizontal error of this dataset is +/- 100 meters. Geologic map data have a horizontal positional accuracy dependent on the "on-screen" method of digital cartography. Map error is induced by: (1) the nominal scale of the aerial photographs on which it is based, with an estimated potential error due to a pen line width of approximately 0.001 being equivalent to approximately 1.5 meters on the ground; (2) the error produced by suturing and stretching air photos during orthorectification, with measured errors ranging from X-Y meters; (3) the digitizing RMS error, which varies with digitizing session from X-Y meters; and (4) the accuracy of the human operator digitizing the geologic linework from the topographic base maps and orthophoto, with an estimated error due to a pen line width of approximately 0.001 being equivalent to approximately 1.5 meters on the ground. 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 coverages included in this project are 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 three reviewers familiar with the dominant geologic rock types and structures and/or the specific geology of the McGrath quadrangle area. Location data were determined visually using topographic maps at scales of 1:63,360 and 1:40,000 scale topographic maps using USGS map bases. Some stations were plotted on 1:63,360 scale Infra-Red and 1:40,000 scale black and white air photos during mapping.
