TSIM: What is it and how does it help you?Thiel Surface Impendance Method (TSIM) is a surface electromagnetic device that uses VLF radio waves at a single frequency to measure apparent resistivity changes in the subsurface. The TSIM technique allows the interpreter to accurately delineate known geological features and identify previously unrecognised discontinuities.
Safe and Cost Effective
The device is battery powered thus eliminating the need for external power sources.
Requires only one person to operate.
As it is a passive tool it avoids the risks associated with explosive, radioactive or other high energy methods
Due to its small size it is lightweight ultra-portable
Features and Benefits
Highly successful in locating the line of oxidation (LOX) throughout central Queensland coalfields.
Significant reduction of LOX drilling and considerable cost saving.
Useful in the identification and delineation of geological structures ( i.e. dykes and faults).
Demonstrated success in mineral exploration and mining, including the determination of the extent of mineralisation boundaries in sulphide deposits.
Considerable hydrogeological applications.
Geoconsult provides a complete service from survey planning and design, access to the TSIM equipment, data acquisition, interpretation and professional reporting.
