magnetic survey techniques

Magnetic survey techniques involve measuring variations in Earth's magnetic field caused by underground rocks with different magnetic properties. By using sensitive magnetometers, surveyors systematically move across an area to detect anomalies that indicate the presence of minerals, fossils, or other geological features. These measurements help map subsurface structures without drilling, guiding exploration and research. The data collected is analyzed to identify target zones of interest based on magnetic differences, providing valuable insights into underground geology efficiently and non-invasively.
