TEM 67 Deep Sounding TEM
Transmitter
Features
-
Used to sound to depths greater
than I kilometer.
-
In the large fixed loop
profiling mode, the unit detects and delineates ore
bodies at several hundred meters depth.
-
Powered by a specialized
motor-generator that can energize loops up to 2000 x
2000m in size.
-
The ability to profile deeply
buried conductors makes the system a principal tool
of mineral exploration.
-
Widespread application
performing deep soundings for groundwater
exploration, mapping saline intrusion, and for
geothermal exploration.
-
Used in regional geological
research where structures and layers can be detected
at depths greater them 1000m.
General
The TEM 67 transmitter is the most
powerful Protem transmitter, replacing the TEM37. Not
only is the TEM67 more powerful than the TEM37 (3,800
watts as compared to 2,800 watts for the TEM37), but the
TEM67 offers a degree of flexibility not previously
available in time domain transmitters; The TEM67 uses
the TEM57-MK2 transmitter with a separate power module
and larger generator (3,500 watts). This means that one
can upgrade from the TEM57-MK2 with the addition of a
TEM67 power module and generator. Conversely, if the
full power of the TEM67 is not required for a particular
survey, much of the weight can be eliminated by using
only the TEM57-MK2 portion.
The Protem 67 system with the 3D
receiver coil is the ideal time domain system for
profiling deeply buried conductive ore bodies, such as
massive sulphides, to depths in excess of 500 meters,
and with the 3-axis BH43-3 borehole probe for time
domain logging to 2 kilometers.
The Protem 67 is also ideal for
deep soundings in ground water exploration, saline
intrusion mapping, geothermal exploration, and regional
geological research where structures and layer
information is required to depths of 1,000 meters or
more.
