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

Metadata Updated: November 10, 2020

This publication, GPR 2015-3, contains geophysical data produced from airborne surveys conducted in 1996 and released in 1997 for 415 sq miles of the Petersville mining district, Alaska by the Alaska Division of Geological & Geophysical Surveys (DGGS). Aeromagnetic and electromagnetic data were acquired during the helicopter-based surveys. During 2004, the same digital data were reformatted for ease of use with modern processing tools, vector files and the 56,000 Hz resistivity grid, were added, and new color maps were produced. Except for leveling of the 56,000 Hz coplanar resistivity grid, no reprocessing of the geophysical data was done. The files represent the end part of the 2004 process. A few maps produced in 1997, such as flight line maps and resistivity maps produced as bluelines, are not reproduced; however, color versions of these data and the data enabling production of these maps are included in this archive. Data provided in GPR 2015-3 include processed (1) linedata ASCII databases, (2) gridded files of magnetic and resistivity data, (3) vector files of data contours, interpreted electromagnetic anomalies, and flight lines, and (4) plot files of selected full-color maps, and (5) an Adobe Acrobat file showing the 56,000 Hz gridded data. A vector file of the interpretation overlay produced by the Contractor for the Petersville data (released previously on paper as DGGS Public Data File 97-8) is also included. All maps produced during 2004 are at a scale of 1:63,360 and are included in HPGL2 (.prn), Adobe Acrobat (.pdf), and postscript (.ps) format.
