An introduction to geophysical exploration

TL;DR: In this article, the Journal of the Geological Society of India (v.92, pp.465-470) has published an article in which the authors present the results of the study.

TL;DR: In this paper, a geophysical investigation using electrical resistivity method is carried out in the eastern part of Sangod Block, Kota District, Rajasthan, India, where a total of twenty-one vertical electrical sounding (VES) data were collected using Schlumberger sounding configuration with the aim of determining subsurface layer parameters (resistivities and thicknesses) and delineating the groundwater potential zones in the area.

TL;DR: In this article, a GP survey was conducted along seven profiles having different lengths in two small sectors of the study area, and a few geoelectrical soundings were carried out to investigate the depth and thickness of the fractured zones.

TL;DR: In this article, the authors identify possible flux zones in the base of the dam using DC resistivity and electrical resistivity tomography (ERT) data acquisition consisted of five ERT lines with 6m of spacing between electrodes, using a Schlumberger array.

TL;DR: In this article, the fundamental principles for calculating velocity spectra displays are outlined and examples are included which demonstrate the depth and detail of geological information which may be obtained from the interpretation of such displays.

TL;DR: In this paper, a model computed on the basis of continuous gravity measurements over the mid-Atlantic ridge and the seismic refraction results given in part 1 is presented to explain the seismic and gravity data obtained over the east Pacific rise but that a deeper compensation is not impossible because of the smaller gradients in the topography and Bouguer anomaly curves.

TL;DR: Vine and Matthews as mentioned in this paper showed that the pattern of local magnetic anomalies on the flanks of a mid-oceanic ridge is strongly lineated parallel to the ridge, and that these magnetic "stripes" represent strips of material in the upper mantle the directions of permanent magnetization of which are alternately parallel and anti-parallel to the present local geomagnetic field.
