Magnetic field anomalies

Magnetic field anomalies are variations or irregularities in Earth's magnetic field caused by differences in the materials and structures within the Earth's crust. These variations occur because certain rocks or minerals, like iron-rich deposits, can strengthen or weaken the magnetic field locally. Scientists detect these anomalies using sensitive instruments to study Earth's composition, geological features, or locate mineral resources. Understanding these magnetic irregularities helps researchers interpret subsurface structures, track tectonic movements, and explore for natural resources, providing valuable insights into Earth's geology and its dynamic processes.
