Geophysical prospecting techniques called "archaeological prospecting" are used to investigate archaeological sites. One of the most popular and effective techniques is geomagnetic survey. Soils and stones have various magnetic mineral contents, and therefore they sometimes have high susceptibility and/or can acquire thermoremanent magnetization through heating, as a result of which they disturb the Earth's magnetic field and produce "magnetic anomalies." By detecting such magnetic anomalies, it is possible to find archaeological sites under the ground without excavation. This paper discusses magnetic minerals and their nature, surveying methods and instruments used in archaeological geomagnetic surveying, magnetic anomalies and their interpretation, and some examples of geomagnetic survey of archaeological sites.
