Fortymile mining district electromagnetic and magnetic airborne geophysical survey, data compilation

The Fortymile electromagnetic and magnetic airborne geophysical survey data were acquired with a DIGHEM-V Electromagnetic (EM) system and a cesium magnetometer. The EM and magnetic sensors were flown at a height of 30 meters (m). In addition the survey recorded data from radar and laser altimeters, a GPS navigation system, 50/60 Hz monitors and a video camera. Flights were performed with an AS-350-B2 Squirrel helicopter at a mean terrain clearance of 60 m along N-S survey flight lines with a spacing of 400 m. Tie lines were flown perpendicular to the flight lines at intervals of approximately 4,800 m

Linedata and gridded data for the aeromagnetic survey of the Holitna basin area, western Alaska; Parts of the Lime Hills and Sleetmute quadrangles

This DVD-ROM publication, GPR 2008-4, contains linedata, gridded data, vector data, and browse graphics produced from a fixed-wing aeromagnetic survey conducted in 1997 of the Holitna Basin area, western Alaska. Aeromagnetic data were acquired for about 3234 sq miles for the Alaska Division of Geological & Geophysical Surveys (DGGS) during this fixed-wing survey.

Iron Creek airborne electromagnetic and magnetic geophysical survey data compilation

Frequency domain electromagnetic data and magnetic geophysical data were collected below a helicopter using a 30 meter (m) long line and a towed bird for the 1997 Iron Creek survey. The geophysical data were acquired with a DIGHEM-V Electromagnetic (EM) system, a Scintrex cesium magnetometer, and a Herz VLF system installed in on AS350B-2 Squirrel helicopter. In addition, the survey recorded data from a radar altimeter, GPS navigation system, 50/60 Hz monitors and video camera. Many of the files for this release were published on paper and available by mail order beginning in 1998. This updated data release provides a compilation of the previously published paper files (in PDF format) and the originating data files...

Major-oxide and trace-element geochemical data from rocks collected in the Tok River area, Tanacross A-5 and A-6 quadrangles, Alaska in 2016

Geologists from the Alaska Division of Geological & Geophysical Surveys (DGGS) and University of Alaska carried out a two-part geologic mapping and geochemical sampling project in the Tok River area of the Tanacross A-5 and A-6 quadrangles (June 12-26 and July 8-26). The Tok River area is adjacent to the Delta mineral belt volcanogenic massive-sulfide (VMS) district, the Peak gold-silver-copper skarn, and the structurally controlled gold and antimony mineralization in the Stibnite Creek and White Gold areas. The Tok River project area includes the Noah (also called Hona) prospect, an intrusion-related copper prospect. The combination of insufficient detailed geologic mapping, historical and current industry interest...
