    East Styx survey area: Airborne magnetic, electromagnetic and radiometric data in line (point), grid, vector, and map formats, Talkeetna, Tyonek, McGrath, and Lime Hills quadrangles, south-central Alaska

    Metadata Updated: July 5, 2023

    This digital publication, GPR 2014-5, contains data produced from airborne geophysical surveys conducted in 2012 and 2013 for the East Styx survey area in the McGrath and Yentna mining districts, Talkeetna, Tyonek, McGrath, and Lime Hills quadrangles, south-central Alaska. Aeromagnetic, electromagnetic (EM), and radiometric data were acquired by helicopter for about 1060 sq miles. CGG's frequency-domain DIGHEM V system was used for the EM data. GPR 2014-5 includes (1) raw and processed linedata; (2) gridded, Google Earth, and Geotiff formats of the calculated linedata; (3) maps of the data and flight lines; and (4) vector files of data contours and flight lines.
