Abstract
The piezoelectric and seismo-electrokinetic phenomena are manifested by electrical and electromagnetic processes that occur in rocks under the influence of elastic oscillations triggered by shots or mechanical impacts. Differences in piezoelectric properties between the studied targets and host media determine the possibilities of the piezoelectric/seismoelectric method application. Over a long time, an interpretation of obtained data is carried out by the use of methods developed in seismic prospecting. Examination of nature of piezoelectric/seismoelectric anomalies observed in subsurface indicates that these may be related (mainly) to electric potential field. In this paper, it is shown that quantitative analysis of piezoelectric/seismoelectric anomalies may be performed by the advanced and reliable methodologies developed in magnetic prospecting. Some examples from mining geophysics (Russia) and ancient metallurgical site (Israel) confirm applicability of the suggested approach.
Highlights
The piezoelectric and seismo-electrokinetic phenomena are manifested by electrical and electromagnetic processes that occur in rocks under the influence of elastic oscillations triggered by shots or mechanical impacts ([1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32])
Because the manifestation patterns of the above phenomena are different in different rocks, these phenomena can be used as a basis for geophysical exploration techniques
The piezoelectric method is an example of a successful application of piezoelectric/seismoelectrokinetic phenomena in exploration geophysics
Summary
The piezoelectric and seismo-electrokinetic phenomena are manifested by electrical and electromagnetic processes that occur in rocks under the influence of elastic oscillations triggered by shots or mechanical impacts (hits) ([1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32]). The piezoelectric method is an example of a successful application of piezoelectric/seismoelectrokinetic phenomena in exploration geophysics. It has been successfully applied in mineral exploration and environmental features research in Russia, USA, Canada, USA, Australia and other countries. Interpretation of seismoelectric/piezoelectric anomalies is often carried out using procedures. Interpretation of seismoelectric/piezoelectric anomalies is oftenitcarried out using procedures similar to those employed in seismic prospecting. In the paper, is shown that quantitative similar to those employed in seismic prospecting. It is shown that quantitative interpretation of expressed anomalies observed in near-surface may be performed using the methods interpretation expressed anomaliesfields. Observed in near-surface may be performed using the methods developed for of potential geophysical developed for potential geophysical fields
