Om denne e-bog
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 properties of rocks, geomagnetic field, magnetometers, transverse magnetization, and measurement of self-potentials. The publication ponders on electromagnetic, electrical, and induced polarization methods. Topics include classification of electromagnetic methods; use of two frequencies in electromagnetic prospecting; moving source-receiver methods; electrode configurations in resistivity methods; and resistivity measurements in boreholes. The text also examines gravity, seismic, and airborne magnetic and electromagnetic methods. The manuscript is a valuable source of information for geologists and mining engineers.
