magnetic prospecting

Magnetic prospecting, also known as a magnetic survey, is a geophysical technique used to explore for buried resources. It involves measuring variations in the Earth's magnetic field at different locations. These measurements can help identify mineral deposits, oil-bearing structures, or even archaeological remains by detecting anomalies caused by differences in the magnetic properties of subsurface rocks. Instruments like magnetometers are used to record these magnetic field intensities, inclinations, and declinations. The collected data is then used to create magnetic maps, which can reveal the size and extent of buried geological features. This method is particularly useful for mapping features in igneous and metamorphic rocks that might be associated with mineral concentrations.123
