Flight-line data for a hyperspectral survey using the HyMap sensor over this area in 2014 where porphyry deposits are exposed. The data are provided in imagery formats.

Report containing tables of geochemical data

Hyperspectral analysis of rock samples using this equipment provide information on the composition and morphology of the minerals in the rock in microscopic detail. Data are provided as imagery in various formats.

Physical properties (density, magnetic susceptibility, and remanent magnetism) from 20,000 rock samples. Data are provided in CSV format.

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

Geologic map compiled from existing sources without generalization, with new or revised data where available. Part of a statewide geologic map database effort in which the structure and content of the data is as consistent as is practical.

Reflectance, mineral predominance, and white mica wavelength position data calculated from an airborne hyperspectral imaging survey of this area using a HyMap sensor in 2014. Data are provided in a format generated by the ENVI software product, CSV, and GeoTiff.

Map at 1:63,360 scale shows the bedrock geology of a special study area within the Chugach National Forest, Alaska. Includes ARC/Info export files and graphics.

Data collected as part of a geological and geophysical framework study

New gravity stations combined here with older measurements taken by other USGS survey trips

Geochemical, x-ray diffraction mineralogical, and electron probe microanalysis (EPMA) data on rocks, soils, and sediments collected near porphyry copper deposits in this area. Data are provided in CSV format.
