Description
Report of Investigation 2006-2 v. 1.0.1, Bedrock geologic map of the Liberty Bell area, Fairbanks A-4 Quadrangle, Bonnifield mining district, Alaska, provides bedrock geologic map of an approximately 131-square-mile area surrounding the Liberty Bell Mine. The geology of the Liberty Bell area, located in the northern Alaska Range foothills, comprises Devonian metasedimentary and meta-igneous rocks of the Totatlanika Schist and Keevy Peak formations, Cretaceous and Tertiary igneous rocks, and overlying unconsolidated Tertiary sedimentary rocks of the Usibelli Group and the younger Nenana Gravel. The complete report, geodatabase, and ESRI fonts and style files are available from the DGGS website: http://doi.org/10.14509/15026.
