Journal ArticleDOI
Three‐Dimensional Electrical Conductivity and Induced Polarization Tomography of a Rock Glacier
TL;DR: In this paper, the electrical resistivity and induced polarization data were collected on an unstable Alpine rock glacier in Val Thorens (Vanoise massif, France) in addition to these field data, and also performed induced polarization measurements during freeze and thaw using a soil sample and the poorly mineralized water, both from this site.
Journal ArticleDOI
Induced polarization of volcanic rocks. 3. Imaging clay cap properties in geothermal fields
André Revil,Youzheng Qi,Ahmad Ghorbani,A. Coperey,A. Soueid Ahmed,Anthony Finizola,Tullio Ricci +6 more
TL;DR: In this article, the authors developed new complex conductivity models using both differential effective medium (DEM) and volume averaging theories accounting for both conduction and polarization of these high cation exchange capacity (CEC) materials.
Journal ArticleDOI
Three-dimensional modeling of frequency- and time-domain electromagnetic methods with induced polarization effects
TL;DR: Three-dimensional FDEM and TDEM modeling with IP effects is developed using the generic partial-differential-equation solver Comsol Multiphysics's application program interface (API) with Matlab, which could be of great importance in quantitatively studying IP effects in theFDEM andTDEM methods, in developing new field configurations, and in educational purposes.
Journal ArticleDOI
Airborne Transient Electromagnetic Modeling and Inversion Under Full Attitude Change
TL;DR: This letter scrutinizes the mechanism of how the attitude change affects the EM response and divides these effects into two parts: the pure attitude effect and the resultant translation effect and introduces a novel method to involve the full attitude change in both modeling and inversion.
Journal ArticleDOI
Induced polarization response of porous media with metallic particles — Part 7: Detection and quantification of buried slag heaps
Youzheng Qi,Abdellahi Soueid Ahmed,André Revil,Ahmad Ghorbani,F. Abdulsamad,Nicolas Florsch,Jeremy Bonnenfant +6 more
TL;DR: In this paper, a least-squares 3D induced polarization (IP) inversion is used to get the subsurface chargeability distribution delimiting the slag heap in the ground.
