Petrographic and geochemical analyses of 50 outcrop samples and 58 drill core samples.

Data derived from the 1994 map "Latest Cretaceous and Cenozoic magmatic rocks of Alaska" compiled by E.J. Moll-Stalcup, D.A. Brew, and T.L. Vallier, published (at 1:2,500,000 scale) in volume G-1 of "The Geology of Alaska" (GSA)

This report makes available a large well dataset so that subsurface stratigraphic data are available in digital form for use within a GIS and in construction of three-dimensional models to address regional stratigraphic and structural questions.

Major and trace element chemistry of rock samples collected in this area, where surrounding rocks host numerous mineral deposits and occurrences. Data are provided in Microsoft Excel and CSV formats.

Geochemical analyses of rock samples collected by the U.S. Geological Survey from surface exposures of host rock and REE-mineralized pegmatites and felsic dikes in this area to provide information on potential sources of co-product and by-product critical elements in domestic mineral deposits and to allow comparison with other REE deposits in peralkaline igneous complexes. Data are provided in CSV format.

U-Pb isotopic data and associated ages of zircon grains from 27 sedimentary samples and one volcanic ash sample from this area. Data are provided in CSV format.
