Methods in Geochemistry and Geophysics, 3: Mining Geophysics focuses on the geophysical methods of ore prospecting, including radioactivity, collection of geophysical data, and field measurements. The manuscript first highlights the role of geophysics in ore prospecting and the general aspects of collection and presentation of geophysical data. Discussions focus on classification of geophysical methods, radioactivity, collection of preliminary information, field measurement, and isoanomaly curves. The text then surveys magnetic and self-potential methods, as well as the general magnetic proper
