Geologic map and associated digital databases of central Alaska. Compilation and reinterpretation of previously published and unpublished mapping at 1:250,000 scale, with limited 1:125,000 and 1:63,360 scale mapping.

A compilation and statistical analysis of 306 density and 706 magnetic susceptibility measurements of rocks from south-central Alaska

New data for 366 previously collected stream-sediment samples, because recently developed analytical methods can detect additional elements of interest and have lower detection limits than the methods used when these samples were originally analyzed.

Geochemical data from selected USGS projects from the 1960s-1980s that were previously not published as digital data. Includes geochemical analyses from 36,498 samples of various types using analytical methods and instruments that were current when those studies were carried out. Data are provided in Microsoft Access, shapefile, and CSV formats.

The data consist of major- and trace-element whole-rock geochemical analyses and major- and trace-element analyses of sulfide minerals determined by electron microprobe and laser ablation–inductively coupled plasma–mass spectrometry (LA-ICP-MS) techniques

GIS data that map potential for tungsten skarn mineralization in permissive tracts in the Yukon-Tanana Uplands, Eastern Alaska, along with tables listing keywords and procedures used to produce the permissive tracts and score them for mineral potential. Data are provided in Esri file geodatabase, shapefile, KML and CSV formats.

Data collected as part of a geological and geophysical framework study

Chemical analysis of 201 samples of rocks thought to be altered or mineralized in an area containing numerous mines.

Geochronology data obtained through radiometric dating of rocks in this area. Data are provided in CSV format.
