TLDR
There have been major improvements in instrumentation, field survey design and data inversion techniques for the geoelectrical method over the past 25 years as mentioned in this paper, which has made it possible to conduct large 2D, 3D and even 4D surveys efficiently to resolve complex geological structures that were not possible with traditional 1-D surveys.About:

Magnetic and Electricalprospections in the Archaeological Site of Xalasco, Northeast of Tlaxcala, Mexico
TL;DR: Tlaxcala was one of the most populated regions of Mesoamerica in pre-Hispanic times; almost one thousand archeological sites have been recorded in its small territory, inhabited at different times during the last three millennia as mentioned in this paper.

Investigation of suspected gulls in the Jurassic limestone strata of the Cotswold Hills, Gloucestershire, England using electrical resistivity tomography
TL;DR: An electrical resistivity tomography survey has clearly indicated the presence of substantial vertical zones of contrasting material beneath a set of conspicuous linear surface hollows that cut across a spur forming part of the Cotswold Hills escarpment in Gloucestershire.

Optimising geological mapping of glacial deposits using high-resolution electromagnetic induction data
TL;DR: Christen et al. as discussed by the authors used a combination of shallow, high-resolution EMI surveying and traditional spear-auger soil sampling along the same transects, was tested in an area of c. 2 km2 around the contaminated, former landfill site at Pillemark on Samso.

2D‐ERT Survey for the Identification of Archaeological and Historical Structures beneath the Plaza of Santo Domingo, Mexico City, Mexico
TL;DR: In this article, the position of the northwest corner of the ancient Mexica wall and whether the Plaza of Santo Domingo became a public square during pre-Hispanic or colonial times were established.

The electrical resistivity log as an aid in determining some reservoir characteristics
TL;DR: The usefulness of the electrical resistivity log in determining reservoir characteristics is governed largely by: (1) the accuracy with which the true resistivity of the formation can be determined; (2) the scope of detailed data concerning the relation of resistivity measurements to formation characteristics; (3) the available information concerning the conductivity of connate or formation waters; and (4) the extent of geologic knowledge regarding probable changes in facies within given horizons, both vertically and laterally, particularly in relation to the resultant effect on the electrical properties of the reservoir as mentioned in this paper.
Book
An Introduction to Applied and Environmental Geophysics
TL;DR: The first edition of the book as mentioned in this paper contains case histories, and descriptions of geophysical techniques not previously included in such textbooks, but the level of mathematics and physics is deliberately kept to a minimum but is described qualitatively within the text.

Occam's inversion to generate smooth, two-dimensional models from magnetotelluric data
TL;DR: In this paper, the authors propose an extension of the existing 1-D algorithm, Occam's inversion, to smooth 2-D models using an extension to the existing Occam inversion.
