Induced Polarization (IP) method
Typically used for locating disseminated metallic ores. Method is based on Induced Polarization Effect on conductive ore or water particles, surrounded by more resistive host rock.
IP method is applicable for locating geological structures and disseminated deposits, where the other geophysical electromagnetic methods are not effective. Resistivity can be measured (and almost always is measured) at the same time.
A separate transmitter and receiver is usually used. A spread of electrodes is spread to the ground before measuring. Length of survey spread varies from tens of meters to kilometers. Reachable depth and resolution of results depends on survey setup and ground conditions. Various survey configurations are applied and always designed based on the investigation target.
We mainly use EMIT SMARTem 24 receivers with a 16-channel breakout box. The transmitter mostly used is the IRIS VIP 5000. We also have experience with other multi-channel hardware, so we can also recommend alternative equipment if required by the project. Geovisor has excellent connections to equipment rental companies and an extensive cooperation network. Our staff has extensive experience in various geophysical equipment.
Client will always receive quality assessed raw data from the surveys. Additionally, we provide the data processing and interpretation of the results. Reporting according to request and introduction to the survey results will be done as requested.
The final product of IP method is usually 2D sections or inverted 3D voxel models of the target.
