Borehole methods are a specialized branch of Geophysical Areas Covered • Seismic Refraction Magnetics. Y1 - 2018 Application of Geophysical Methods to Waste Disposal Studies 5 Electrical resistivity distribution is useful for determining shallow and deep geological and hydrogeological conditions. In the past, most engineers applied their conventional method with rare to any other alternative method. Initial geophysical trials investigated the application of SQUID sensors for transient electromagnetic (TEM) geological exploration, where a large surface transmitter coil is used to induce eddy currents in the ground and the very weak, time variant secondary magnetic fields are measured at the surface (e.g. This edited volume is based on the best papers accepted for presentation during the 1st Springer Conferen 1, 2000 Integrated Interpolation Methods for Geophysical Data: Applications to Mineral Exploration Matthew Kay1 and Roussos Dimitrakopoulos1,2 Received 5 December 1999; revised 14 February 2000 Geophysical data are used routinely in mineral exploration to delineate the geology of an area. • INTRODUCTION • Geophysics is the application of the principles of physics to the study of the Earth. Geophysical methods have been a part of the construction engineering toolbox for decades (e.g., seismic methods for foundation design; Peck et al., 1974) and, although adoption of the technology over this time has been slow, their use on major infrastructure projects has now become routine. The array of geophysical technologies used in volcano hazards studies - some developed originally for volcano monitoring - is breathtaking, ranging from satellite remote sensing to infrasound methods, including virtually every method used in resource exploration except large-scale seismic reflection. There is a growing demand for using non-destructive geophysical techniques to internally image dam condition and facilitate the early detection of anomalous phenomena. 62 34

Table 16.1 Typical applications of surface geophysical methods (Benson et al, 1982). Explorationists employ multiple geophysical methods, as each can provide unique information regarding the earth’s subsurface and the potential hydrocarbon prospects contained therein. More re cently, it has been used for environmental It describes details of applicability and limitation, field procedure, analysis and interpretation of geophysical methods in simple terms. The left column of the Matrix indicates 32 possible applications and the top row lists the fourteen most commonly used geophysical methods that can be employed for these applications. 0000011190 00000 n
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. In some cases these methods may be all that the archaeologist is able to use at some sites.

There are exceptions. Part IV describes major geophysical electromagnetic methods—direct current (DC), induced polarization (IP), magnetotelluric (MT), and controlled-source electromagnetic (CSEM) methods—and covers different applications of EM methods in exploration geophysics, including minerals and HC exploration, environmental study, and crustal study.
