Geophysical Prospection of Archaeological Sites by Examples

By: Harald von der Osten

Introduction

Different geophysical methods are used for detection, classifying and documentation of various archaeological objects.

The project Geophysical Prospection of Archaeological Sites of the government of Baden-Württemberg, Germany, was started in the end of 1991 by the author. Up to now methods used are: Geomagnetics, Geoelectrics, Electromagnetic Induction and Ground Penetrating Radar.

Some results of prospections are presented on this site. To view results of geomagnetic prospections for example just click at the button in the left frame.

An overview of the instrumentation used for geophysical surveys is given in the following table.

Method	Equipment / Instruments
Ground Penetrating Radar	SIR-2 manufactured by GSSI antennas used: 200 MHz, 400 MHz, 500 MHz, 900 MHz, 1500 MHz
Electromagnetic Induction	electromagnetic instruments: EM-61 and EM-38 from Geometrics multifrequential instruments
Geomagnetics	Fluxgate Gradiometer: FM-36 (1991-2004), FM256 (2004-...) from Geoscan Research Cs-Gradiometer: Cs-3 sensors from Scintrex, electronics from picodas Group
Geoelectrics	Resistivity-Meters: RM-15 from Geoscan Research and Syscal R2 from Iris Instruments "semi-self-made" tomographic instruments

NOTE: No informations on the locations are given in those cases where no excavations were carried out so far, but where the results may be of great interest for people loving digging for their own at unusual hours....
