A magnetic anomaly refers to a deviation from the expected Earth’s magnetic field, often caused by variations in the distribution of magnetic minerals in the underlying rocks. These anomalies are crucial in geophysical surveys for identifying mineral deposits, oil reserves, and understanding geological structures beneath the Earth's surface.

Geophysical surveys are a critical tool in the exploration and analysis of the Earth's subsurface, utilizing a variety of physical methods to detect and map the distribution of properties such as density, magnetism, and electrical conductivity. These surveys are indispensable in fields ranging from mineral exploration to archaeological site investigation, providing non-invasive means to understand what lies beneath the surface without the need for extensive excavation.
