Moran (Melozitna and Tanana Quadrangles) Geophysical Survey

The digital data below was produced from airborne geophysical surveys conducted in 2009 for the Moran survey area in the south-central Melozitna mining district, Melozitna and Tanana quadrangles, central Alaska. Aeromagnetic, electromagnetic (EM), and radiometric data were acquired by helicopter for about 653 sq miles. Fugro Airborne Survey's frequency-domain DIGHEM V system was used for the EM data. It includes (1) raw and processed linedata; (2) gridded, Google Earth, and Geotiff formats of the calculated linedata; (3) maps of the data; and (4) vector files of data contours and flight lines. A future publication will include the technical project report, interpretation map, and EM anomalies, as well as other files.
