Amasya, Turkey

The Oluz Mound is a very important ancient Turkish settlement with a history stretching back 4,500 years BC.

Objective

To help an on going arcaeological excavations and to show possible structural extensions or new remains on the side by using the Geophysical Electrical Resistivity Tomography (ERT) imaging method.

Layout

The 3D electrical resistivity imaging electrode layout of 13x8 electrodes is placed on the ground surface of the ancient archaeologica site. There are a total of 104 electrodes and the grid uses a symmetric 4 meter electrode spacing. The 3D survey grid dimensions were 48x28 meter giving a total of 1344 m2 in the study area.

Instrument

The AGI SuperSting R1/SIP/SP/Wi-Fi resistivity instrument with a 56 electrode SwitchBox and EarthImager 2D and EarthImager 3D software were used.

Array type used

The Pole-Pole array was used to collect the 3D electrical resistivity imaging data set.

Notes on color graphics

  • The red-yellow colors of higher resistivity values correspond to possible walls and
  • The blue-green colors of low resistivity values correspond to soil areas.

Additional Geophysical techniques used

GPR: The wall anomalies coincidence with the ground penetrating radar survey results.
