Geoelectric for measures in Archaeology

The geoelectric surveys are among the most used geophysical methods for studying the underground in archaeological contexts
the purpose of geoelectric measurements is to derive information regarding the geometry and the location of anthropogenic elements buried in the light of their electrical properties.
In particular, the method of the resistivity is achieved through the measurement of the difference of electric potential at different points on the terrain surface. The aim is to reconstruct the resistivity models of the subsurface through a reversal of the data acquired in the campaign process.
 
This type of non-invasive measurements are based on the principles that describe the electrical conduction through a medium: the more a substance is left to cross from the charge carriers, it is defined more conductive; conversely it is defined resistive.
This method is called a "non-invasive" not providing significant soil disturbances such as excavations, holes or wells; the technique only provides the entry for a few cm of metal electrodes in key contexts such as historic flooring, paving and paving stones, this with due care, can not be considered "invasive".
The method of geoelectric resistivity provides for the energization of the ground (generally through a battery) with direct current and a direct measurement on the soil surface of the potential difference.
To achieve resistivity measurements generally using 2 conductive electrodes which, in contact with the ground, ermettono the placing of the electrical current, in this manner is measured the potential difference.
