This project is part of the Alaska Airborne Geophysical/Geological Mineral Inventory Program funded by the Alaska State Legislature and managed by State of Alaska, Department of Natural Resources (DNR), Division of Geological & Geophysical Surveys (DGGS). Partial funding for the 2003 geologic mapping was also provided by the U.S. Geological Survey, National Cooperative Geologic Mapping Program, under STATEMAP award number 03HQAG0055. The views and conclusions contained in this document are those of the authors and should not be interpreted as necessarily representing the official policies, either expressed or implied, of the U.S. Government. The following people are recognized for their various contributions to this map: C.C. Puchner, M.R. Hayes, and R.E. Meyers of International Tower Hill Mines, Ltd. (data, interpretations, access to drill core, and geological discussions); C.J. Freeman and Avalon Development Corp. (data and geologic discussions); D.C. Bradley and J.V. Jones of U.S. Geological Survey and P.B. O'Sullivan and R.A. Donelick of Apatite to Zircon Inc. (detrital zircon geochronology); J.N. Christensen of Lawrence Berkeley National Laboratory (attempted Sm-Nd geochronology of the Amy Creek metabasite); F.R. Weber, R.B. Blodgett, J.A. Dumoulin (geologic discussions); R.J. Newberry (gold microprobe study); W.R. Bolton (hydrogeologic discussions); J.G. Clough and R.R. Reifenstuhl (sedimentary rock discussions); P.E. Gallagher, S.A. Hicks, L.A. Staft, C.L. Browne, A. Africa, and T.B. Fristoe (student interns/field assistants); S.M. Karl and T.D. Hubbard (technical reviewers); P.E. Gallagher (cartographic and GIS advice); J.Y. Foley (donated gold sample); Alaska Placer Development, Inc., and Placer Dome Exploration (unpublished company data). The geologic map database was converted to GeMS, quality controlled, and then finalized by DGGS staff Chris Wyatt and Mike Hendricks. Geologic map conversion to the GeMS standard was funded by the USGS National Cooperative Geologic Mapping Program under StateMap award number G20AC00367, 2020, and the State of Alaska General Fund. The views and conclusions contained in this document are those of the authors and should not be interpreted as necessarily representing the official policies, either expressed or implied, of the U.S. Government.
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.
