Gravity/Magnetic Interpretation Extension Course Outline

The Gravity/Magnetic Interpretation Extension course is for Geophysicists who need to interpret Potential Field data and obtain an estimate of the depth of the sources that cause anomalies using Euler Deconvolution and Source Parameter Imaging. It also includes the determination of the edges of Magnetic Sources and the Keating Magnetic correlation coefficients used to locate Kimberlite anomalies.
