“…The porewater inside the overburden will regularly be renewed by rainwater containing a large supply of oxygen. Therefore, the porewater in the overburden will have high redox potential (Lile, 1996). Thus, it can be thought that such similar phenomena may be occurring over the buried archaeological structures, which consist of materials with ferrous and ferric ions.…”

The self-potential (SP) method is very rarely used in archaeological prospection because related phenomena are not very well known. The aim of this study is to discuss the different SP phenomena that might be observed at archaeological sites, and therefore the SP method was applied at different archaeological sitesin Anatolia (Turkey), such as Acemh˛yˇk, Amorium,Burgaz and Ulucakh˛yˇk archaeologicalareasandthe Sinopamphoraeworkshop site.These studiesindicatedthat SPanomalies existed over both burned or unburned materials at archaeological sites, such as walls, pits, kilns, etc. Furthermore,SPanomalieswere also found overareas of complex soildistributionandvisible physical changes on the surface. Other kinds of SP anomalies were also observed in those archaeological structureslocatedverycloseto the coastline.Theseresultswere confirmedbyarchaeologicalexcavations, which were carried out aftergeophysical surveysin the areas studied. All the studies supported that electrokinetic and electrochemical potentialsmight be the main cause of SPanomaliesin the buried archaeological structures.The SP data collected with the gradient and total measurement techniques were processed by forward and inversion methods, and the main SP parameters (h, Q and x 0 ) were determined. In addition, the SP results were compared with other applied geophysical methods such as resistivityand magnetic

“…To obtain more accurate results, the effect of the distance to electrode A can the electrochemical basis of SP anomalies and calculated that the largest graphite conductor anomalies should be approximately -400 mV. Experimental data demonstrates that the largest anomalies do occur over graphite schists, but anomalies as large as -1000 mV are not uncommon (Lile, 1996). A negative polarity with a large amplitude is measured above the lowest resistivity zone point of an SP anomaly.…”

Application of integrated geoelectrical methods in Khenadarreh (Arak, Iran) graphite deposit exploration

This paper is devoted to application of SP, resistivity and mise-a-la-masse method in Khenadarreh (Arak, Iran) graphite deposit exploration. Mise-a-la-masse method is one of the main geophysical exploration methods used to investigate conductive bodies with outcrops on the surface or in exploratory pits. By integrating mise-a-la-masse results with other geoelectrical methods, such as self-potential and resistivity surveys, useful results can be acquired. Powerful survey design, data processing and interpretation methods can make geoelectrical surveying results more reliable. Here, we applied integrated geoelectrical methods to explore the Khenadarreh-bala graphite deposit in the Sarband region of the Markazi province, Iran. We present a new and simple method for processing and interpreting mise-a-la-masse data, which corrects for the effect of distance from the current electrode in the conductive body. After correction, the residual potential values corresponded with the SP results and the apparent resistivity pseudosections. The geophysical results were confirmed by drill holes in the study area.

Self-potential (SP) method is one of the most non-expensive and unsophisticated geophysical methods. However, its application limits absence of reliable interpreting methodology, first for the complex geological-environmental conditions. The typical disturbances appearing in the SP method are discussed. To exclude these noise components before the quantitative analysis, some ways for their removing (elimination) are presented. Some brief review of the available interpretation methods is presented. For the magnetic method of geophysical prospecting, special quantitative procedures applicable under complex physical-geological environments (oblique polarization, uneven terrain relief and unknown level of the normal field), have been recently developed. Earlier detected common peculiarities between the magnetic and SP fields have been extended. These common aspects make it possible to apply the advanced procedures developed in magnetic prospecting to SP method. Besides the reliable determination of the depth of anomalous targets, these methodologies enable to calculate the corrections for non-horizontal SP observations and direction of polarization vector. For classification of SP-anomalies is proposed to use a new parameter – 'self-potential moment'. These quantitative procedures (improved modifications of characteristic point, tangent techniques and areal method) have been successfully tested on SP models and employed in real situations in mining, archaeological, environmental and technogenic geophysics. The obtained results indicate practical importance of the developed methodologies.
