A scientific method of prospecting that measures the physical properties of rock formations. Common properties investigated include magnetism, specific gravity, electrical conductivity and radioactivity. Geophysics

Systematic collection of data on the variation of physical properties in rocks and soils.

A method used to determine the physical parameters of rock formations for the purpose of detecting a potential metallic source. Common properties measured include magnetism, specific gravity and elect [..]

Geophysical survey is a non-intrusive form of investigation and can be a rapid and cost-effective method of identifying and mapping sub-surface archaeological remains. It can provide useful information on the location, extent, character and possible period of sub-surface remains. This information can then be used to try and avoid or reduce impact o [..]

Collection of information associated with subsurface features. Archaeologists often use the information they collect to detect and map subsurface features without having to do any destructive or unproductive excavating
