Geochemical and geologic reconnaissance of a part of the Fortymile area, Alaska (OCoLC) Material Type: Document, Government publication, National government publication, Internet resource: Document Type: Internet Resource, Computer File: All Authors / Contributors: Helen Laura Foster; Sandra H B Clark; Geological Survey (U.S.). A geochemical and geological reconnaissance of part of the Seventymile River area (fig. I), Eagle quadrangle, Alaska, was conducted during the summer of as a part of the U.S. Geo- logical Survey's Heavy Metals Program. The principal investiga- tion was in the Eagle D-2 and D-3 quadrangles, but some sampling.

We present here the initial results of a petrographic, geochemical, and isotopic study of Mesozoic intrusive rocks and spatially associated Zn-Pb-Ag-Cu-Au prospects in the Fortymile mining district in the southern Eagle quadrangle, Alaska. Analyzed samples include mineralized and unmineralized drill core from and exploration by Full Metal Minerals, USA, Inc., at the Little Whiteman. The Fortymile River area lies within the Yukon-Tanana lithotectonic terrane of east-central Alaska. This terrane is a mosaic of several lithotectonic assemblages, each with a coherent lithologic, metamorphic, and deformational history. Previous workers have shown that the Fortymile River area is underlain by rocks of the Seventymile, Taylor Mountain, and Nisutlin by: 5. 15 / A geochemical orientation study for lead and zinc in the Fairbanks, Alaska, area, , 17 pages, $ 4 16 / Development of the Spectrographic Element Geochemical Analysis, $ 2 Alaska Professional Report, Department of Natural Resources, Division of Mines and Geology.
