Shaw Creek and Shawnee Peak airborne magnetic and radiometric geophysical survey

Abstract

The Shaw Creek and Shawnee Peak airborne magnetic and radiometric geophysical survey covers parts of the Big Delta and Eagle quadrangles northeast of Delta Junction, Alaska. Magnetic and radiometric data were collected with a helicopter July 4-25, 2020 by MPX Geophysics LTD. A total of 10,100 line kilometers were collected over approximately 2,600 square kilometers. The magnetometer was mounted to a forward-facing fixed boom (stinger). The radiometric crystals were located in the cabin of the helicopter. Data were collected in eight named blocks. Mertie Mountains, Shaw Creek, and Volkmar River have a line spacing of 400 meters (m) and a mean ground clearance of 130 m. Stoneboy has a line spacing of 200 m and a mean ground clearance of 80 m. Eagle, Echo, Healy, and LMS-X have a line spacing of 100 m and a mean ground clearance of 80 m. The data, as well as additional metadata, are available from the DGGS website: http://doi.org/10.14509/30551.
