What Are Very Low Frequency Electromagnetics?

 
Measuring the conductive properties of metals and other materials is nothing new. Comparing the conductive properties of materials is one of the most accurate methods used to identify unknown materials. This same principle can be used to identify important elements such as base metal sulphides that are present beneath the ground surface.
 
Very Low Frequency (VLF) Electromagnetics refers to the practice of introducing small currents into the ground via a probe and measuring the resulting secondary electromagnetic field which is created. The presence of conductive materials will cause the electromagnetic fields to increase accordingly. A VLF Electromagnetic survey is used to collect data about the electromagnetic fields from marine signals or naturally occurring sources. The data is then analyzed and interpreted to assist with geophysical mapping of conductive materials in the survey area.
 
VLF Electromagnetics surveys can be used alone to gather important electromagnetic data, but they are also used with airborne magnetics surveys to gather greater levels of geophysical data for mapping purposes.
 

Who Uses Very Low Frequency Electromagnetics?

 
VLF Electromagnetic surveys are very important metal prospecting tools for mining and mineral exploration companies. Geophysicists are interested in acquiring this data for geological mapping. Governments and environmental safety organizations can use VLF surveys to test for the presence of groundwater as well as potentially unsafe electromagnetic fields around populated areas.
 
The option to execute airborne VLF electromagnetic surveys has greatly increased the cost efficiency of these surveys to the point where more organizations are taking advantage of the mapping possibilities for larger areas of interest.
