Publication_Date: 2016 Title: Geologic map of portions of the Livengood B-3, B-4, C-3, and C-4 quadrangles, Tolovana mining district, Alaska Geospatial_Data_Presentation_Form: geodatabase Series_Information: Series_Name: Report of Investigation Issue_Identification: RI 2016-5 Publication_Information: Publication_Place: Fairbanks, Alaska, United States Publisher: Alaska Division of Geological & Geophysical Surveys Other_Citation_Details: 39 p., 1 sheet, scale 1:50,000 Online_Linkage: https://doi.org/10.14509/29665 Description: Abstract: Geologic map of portions of the Livengood B-3, B-4, C-3, and C-4 quadrangles, Tolovana mining district, Alaska, Report of Investigation 2016-5, presents a geologic map of portions of the Livengood B-3, B-4, C-3, and C-4 quadrangles. The Livengood area is a historically productive placer mining area approximately 80 road miles north of Fairbanks, Alaska. It has produced approximately 542,000 ounces of gold since 1914. The map area covers most of the 229-square-mile Livengood airborne magnetic and electromagnetic geophysical survey. DGGS staff conducted geologic mapping and field investigations in 2003 and 2010. Outcrop map data from the 1982 DGGS field projects were also incorporated in field planning and final geologic interpretation. The map and accompanying report synthesize DGGS and industry geologic data in a 1:50,000-scale comprehensive geologic map to build a better understanding of the geology and mineral-resource potential of the Livengood area. The complete report, geodatabase, and ESRI fonts and style files are available from the DGGS website: http://doi.org/10.14509/29665. Purpose: The bedrock, mineral, and surficial geologic interpretations and investigation of the Tolovana and Rampart mining districts near Livengood, Alaska, were implemented as part of an ongoing DGGS program to provide geologic mapping and supporting geochemical, petrologic, and geochronologic data to foster a better understanding of Alaska's geology and mineral potential.

DGGS mapping in 2003 focused on the Livengood southeast C-4 and southwest C-3 quadrangles and was published as PIR 2004-3 and RI 2013-2. The 2003 project included approximately 90 person-days of fieldwork. The 2010 DGGS program consisted of approximately 100 person-days of bedrock geologic mapping fieldwork in the north half of the Livengood B-4 and the northwest B-3 quadrangles. The 2003 and 2010 programs combine for 2,444 handheld-GPS-located geologic mapping stations. The map also incorporates outcrop map data from the 1982 DGGS field projects. Mapping was supplemented with geochemistry, airborne geophysical survey data, radiometric and fossil dates, and magnetic susceptibility measurements. The conceptual framework for the geology incorporates key ideas from preexisting literature with new data and interpretations developed from field mapping and analytical findings. The accompanying map or report provides a comprehensive bibliographic reference list of prior work used to identify and delineate rock units and structural elements.
