The Radio Frequency Electromagnetics (RF-EM) is the fastest landborne geophysical method for profiling fractures. Due to the extended frequency range it is even suitable for soundings.
This method is an extension of the traditionall Very Low Frequency Electromagnetics (VLF-EM) method, which is very well known in mining exploration.
The frequency extension and the continous profiling mode allow a strong enhancement of data quality from VLF-EM to RF-EM.
The construction of an automatically oriented antenna, which may be fixed behind a car, allows to record data with a very high resolution without velocity penalty. The measuring car may drive up to 40km/h while measuring with a resolution better than 1m.
This research was financed by the Swiss Research Foundation.
