Dear colleague:

The most popular method is pole to pole, specially in its version “twin-probe”.

I should recommend on that topic: (2009) G.N. Tsokas, P.I. Tsourlos & N. Papadopoulos Electrical resistivity tomography: A flexible technique in solving problems of archaeological research.

And the classic: Aspinall, A. & Lynam, J.T. 1970 An induced polarization instrument for the detection of near surface features. Prospezzioni Archaeologiche, 5

Nevertheless, configurations vary depending on conditions and needs.

I hope it will be of use for you.

Oscar

Like Mr Jimenez stated: your configuration needs to be adapted to the condition and needs of your research. Nothing in archaeology is straight forward enough to warrant formula that can always be applied in all situations. You might want to get in contact with geographers, explain the them your research question and the situations you are working under and they will most likely be able to advise you on what equipment and configuration to work with.

Sincerely,

Veerle

Dear Anand may I ask what you are looking for?  What conditions are in the landscape, moist dry porous sandy clay etc? If you are looking for minerals, I have info. I have been working with platy polar silicates in clays. These fine muds that create "spontaneous potentials" I believe this combination is the preservation agent in my mud fossils.

[email protected] if I can help.

Pole-Pole array was specially designed for archaeological prospection.

Wenner array is the standard against which other arrays are assessed.
