magnetometrinë

Magnetometria is a geophysical method used to measure and map variations in the Earth's magnetic field. These variations, or anomalies, are caused by differences in the magnetic properties of rocks and subsurface structures. Instruments called magnetometers are used to detect these subtle changes. Magnetometers can be towed behind ships for marine surveys, flown in aircraft for airborne surveys, or carried by individuals for ground-based surveys. The data collected by magnetometers is then processed and interpreted to create magnetic anomaly maps. These maps can reveal geological features such as fault lines, mineral deposits, and buried objects. Magnetometry has a wide range of applications including mineral exploration, geological mapping, archaeological investigations, and unexploded ordnance detection. It is a non-invasive technique, meaning it does not require drilling or excavation to gather information. The sensitivity of magnetometers has increased significantly over time, allowing for the detection of smaller and more complex magnetic signatures.
