What Are Very Low Frequency Electromagnetics?
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.
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?
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.
