Geophysical Techniques

Geophysical techniques in archaeological geology refer to non-invasive methods used to detect and map subsurface archaeological features and materials through the measurement of physical properties of the Earth, such as magnetic, electrical, or seismic characteristics. These techniques aid in the identification and interpretation of archaeological sites without the need for excavation.

Key Terms

Ground Penetrating Radar (GPR)
A geophysical method that uses radar pulses to image the subsurface.

Example: GPR can reveal buried structures without excavation.

Magnetometry
A technique that measures variations in the Earth's magnetic field caused by archaeological features.

Example: Magnetometry can locate ancient hearths or kilns.

Electrical Resistivity
A method that measures the resistance of the ground to electrical current, indicating different materials.

Example: High resistivity may indicate dry soil or stone walls.

Seismic Surveys
Techniques that use seismic waves to explore subsurface structures.

Example: Seismic surveys can help map ancient riverbeds.

Anomaly
A deviation from the expected pattern in geophysical data.

Example: An anomaly may indicate a buried wall or feature.

Subsurface
The layer of soil and rock beneath the Earth's surface.

Example: Archaeologists study subsurface layers to understand past human activity.
