Magnetic Field Surveys

Knowledge in the Field

Total field and total field vertical gradient methods are used to map rocks of differing magnetic susceptibility. While they are often used as general mapping tools, magnetic field surveys are useful in exploring a wide variety of northern targets including kimberlites, skarn, VMS, porphyry, IHG, iron formation and structurally hosted gold deposits.

AGL Delivers

Aurora Geosciences offers total magnetic field surveys with GEM and Scintrex proton precession magnetometers and gradiometers. We offer GPS gridding to permit rapid reconnaissance coverage without the requirement of a physical grid in areas where the tree canopy permits.

All of our equipment is fully digital, permitting rapid data acquisition and in-field processing. Frequency domain filtering and a variety of image analysis techniques can be used to accentuate signatures of interest.  Final output is provided in colour or black line contour and shaded contour map formats.
