This website beta version contains information on geophysical methods, references to geophysical citations, and a glossary of geophysical terms related to environmental applications. In addition, the data provide most of the guidance on where to position drillholes. Electrical Resistivity Method: In this method the electrical resistivity of the formations is measured by passing a current. [10] See also [ edit] Seismic surveying is the most important of the three main types of geophysical prospecting. Measurements of the parameters of these fields are made on the surface of the earth (land and water), in the air, and underground (in wells and shafts). It should be noted that there are five main methods of geophysical prospecting which include geoelectrical, seismic, radiometric, gravity, and magnetic which are commonly used in metal detection. shubham shukla Geophysical exploration Abhineet Godayal CE conventional resistivity logs university of sargodha They tend to work well because kimberlite pipes, the diamond hosting rock, generally have properties that are different from the surrounding rock.

Seismic methods Electric and electromagnetic methods Sub-surface methods Well logging methods Through either ground or airborne surveys, geophysical companies employ the use of magnetic, radiometric, electromagnetic and gravity surveys to detect anomalous responses which may indicate the presence of mineral deposits. For the different methods: physical principles, equipments, acquisition, data processing and interpretation; applications. Technologies used for geophysical surveys include: [1] Seismic methods, such as reflection seismology, seismic refraction, and seismic tomography. The table identifies the utility of each method in airborne, ground, or borehole applications.

Each of the major geophysical methods is treated systematically developing the theory behind the method and detailing the instrumentation, eld data acquisition techniques, data processing and . Properties such as trace element abundances are analyzed systematically to locate anomalies. These properties include but are not limited to soil resistivity, shear modulus, Poisson's ratio, and percentage moisture content. Assessment Other: 100.0% Rather, they add to it. By itself, no geophysical anomaly can simply be correlated with lithology (Lyatsky, 2004). The gravity method of geophysical prospecting is based on the fact that the gravitational attraction of sub-surface bodies directly up on their masses and inversely upon second power of the depth of their occurrence (i.e., their distance from the surface of the earth).
