WHAT IS "MAGENETIC SUSCEPTIBILITY" AND WHEN SHOULD WE MEASURE IT?
|
|
Magnetic Susceptibility is the intrinsic property that determines the amount of magnetism a rock can have in a
given magnetic field. Rocks are composed of minerals which vary in their magnetic susceptibility and magnetite
accounts for most of the susceptibility observed. Thus the measurement of susceptibility can be used before
magnetic surveys take place, to ascertain which rocks will be detectable magnetically, and to what degree.
This can be undertaken in the field on outcrop or on samples in the laboratory. It is also used after
drilling has taken place to measure the drill core and so determine from what rock types and at what
depths the observed magnetic responses have originated.

ADDITIONAL MAGNETIC SUSCEPTIBILITY TOOLS
|
|
In addition to the GMS-2, which is completely designed and manufactured in Australia, Geo Instruments
are also able to offer other hand-held magnetic susceptibility meters for both field and laboratory use
These are specifically the Hand-held
KT-10 Magnetic Susceptibility Meter from
TerraPlus
of Canada, and also the MS2 System from
Bartington Instruments in the
U.K..
Both companies also offer an extensive range of other instruments, in particular
near surface
geophysical
equipment
(magnetometers,
resistivity meters,
borehole logging
systems and GPR)
from TerraPlus, and
high precision, low field
magnetic sensors (single and 3-component) from Bartington Instruments.
