Electromagnetic Induction Methods in Mining Geophysics from 2008 to 2012 Richard Smith Received: 21 September 2012/Accepted: 19 March 2013/Published online: 9 April 2013 Springer Science+Business Media Dordrecht 2013 Abstract In the period from 2008 to 2012, the topic of electromagnetic (EM) induction methods applied to mineral exploration has been the subject of .

Overview. VLF survey methods use verylowfrequency, radio communiion signals to determine electrical properties of shallow bedrock and nearsurface soils, primarily as a reconnaissance tool. VLF profiles can be run quickly and inexpensively to identify anomalous areas warranting further investigation by other surveys, drilling or sampling.

Appliion of VLFEM method in mineral exploration of ... The VLFEM 16 survey was conducted using a Geonics VLFEM 16 instrument at halfstation spacings. The transmitting station used was Seattle, Washington ( NLK 2^.8 khz. ). The field is in Hmode with the transmitting station at right angles to the bearing of the operator from the ...

Mineral Exploration Using Vlf Em Method Mineral Exploration Using Vlf Em Method. VLF anomalies at contacts between Precambrian rocks . Four examples of very low frequency (VLF) electromagnetic (VLFEM) anomalies within the Basement Complex in the Igbeti district, southwestern Nigeria, revealed that the method can be successfully used to map nonconductive mineral bodies .

for a mineral exploration survey ... Also, on sites that have very hard surface material, there is no other common method for directly measuring Efield behaviour. This is possible with VLF equipment because the frequencies involved are higher than other common geophysical methods, so capacitive ground electrodes can be used. These do not require penetration of the surface. Unfortunately ...

 · VLFEM and radiometric methods were applied together in the study area to utilize their integrated results for the uranium exploration. Results indie good correlation between VLF data and radiometric data. This is because these radiometric signals are associated with shallow uranium mineralization which is associated with altered minerals that give conductivity contrast with the ...

The very low frequency electromagnetic (VLFEM) method is a passive geomagnetic method using the radio signals in the frequency range of 1530 kHz; it is considered as the best reconnaissance method among electromagnetic ones, and is extensively described in the literature (Paterson and Ronka 1971, Wright 1988, McNeill and Labson 1991). It was primarily applied for mineral exploration .
