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

This digital publication, GPR 2014-2, contains data produced from airborne geophysical surveys conducted in 2012 and 2013 for the Farewell survey area in the McGrath and Yentna mining districts, McGrath and Lime Hills quadrangles, south-central Alaska. Aeromagnetic, electromagnetic (EM), and radiometric data were acquired by helicopter for about 954 sq miles, which includes the 100 sq mile Dalzell Creek area previously released. This publication incorporates data from the previously published Dalzell Creek area into the linedata, grids, maps, and other derivative pieces of this publication. CGG's frequency-domain DIGHEM V system was used for the EM data. GPR 2014-2 includes (1) raw and processed linedata; (2) gridded,...
