Experimental Geoelectric Investigation within the Gold Field in Ukraine

2nd EAGE St Petersburg International Conference and Exhibition on Geosciences, 2006
The results of experimental geoelectric investigation within the gold field in Ukraine are given. The obtained data show that developed express-technology of geoelectric research can be used for ore (and gold) fields prospecting.

Study on the variation characteristics of the geoelectric field preceding earthquakes

Acta Seismologica Sinica, 2004
Earthquake events occurred in Nantong, Jiangsu Province on Nov. 3, and Dec. 25, 2001 in which the biggest magnitudes were M L=3.8 and M L=4.1, respectively. This paper firstly explains the principle of the eliminating noise method by the multi-dipole observation system of geoelectric field.

Mathematical modelling of some geoelectrical fields in archaeological exploration

4th EEGS Meeting, 1998
The geoelectrical fields observed on rugged topography (necropolis) are considerably complicated by the effect of unevenness of the earth's surface. This effect can be eliminated in geophysical interpretation. For solving the inverse problem of geoelectrical investigation in archaeological exploration it is necessary to determine the subsurface ...

Geoelectric Fields and Geomagnetically Induced Currents in the United Kingdom

2004
This thesis investigates geo-electric fields in the United Kingdom with particular regard to Geomagnetically Induced Currents (GIC) in the Scottish Power electricity transmission network (SPTN). The joint spectral characteristics of Scottish Power GIC and Eskdalemuir magnetic observatory data are analysed, and GIC are shown to be coherent with magnetic

Induced Geoelectric Fields as a Key Space Weather Variable

Many of the effects of geomagnetic field variations, apart from those on devices using the geomagnetic field directly, are through induction of electric fields as described by Faraday’s Law. Such electric fields in turn cause an Ohmic effect in the Earth and conducting infrastructure, giving rise to potentially harmful geomagnetically induced currents (
