Geologic map of portions of the Livengood B-3, B-4, C-3, and C-4 quadrangles, Tolovana mining district, Alaska

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.
