An integrated geophysical survey using both the electrical resistivity tomography (ERT) and groundpenetrating radar (GPR) methods was undertaken over a cave of great archaeological interest in southern Italy. The survey was performed to assess the stability of the carbonate rock roof of the cave. A geophysical survey was preferred to boreholes and geotechnical tests, in order to avoid the risk ...

Ground Penetrating Radar (GPR) is an effective and practical geophysical imaging tool, with a wide set of applications in geological mapping of subsurface information. This research study aims at determination of the geophysical parameter differences in the subsurface geological structures and construction of a 3D fracture model. GPR and resistivity methods were applied to detect the unstable t...

Petrophysical properties of 585 rock samples from the Suhbaatar-Ulaanbaatar-Dalandzadgad geophysical profile in Mongolia are presented. Based on the rock classifications and tectonic units, petrophysical parameters (bulk density, magnetic susceptibility, intensity of natural remanent magnetization, and Köenigsberger ratio) of these rocks are summarized. Results indicate that (1) significant den...

Since late 2018 the Geological Survey of New South Wales (GSNSW) has undertaken a major project to catalogue, quality-assure and release company geophysical survey data across state. A key deli...

The attention given the natural geologic background of a site and its influence on geophysical sensors has grown considerably over the past several years, primarily because of the governmentsupported unexploded ordnance (UXO) technology demonstrations and government mandated UXO cleanup activities. Explosive and ordnance detection (EOD) teams have encountered difficulties at sites thought to be...
