DC Resistivity And Induced Polarization Methods Geophysical Resistivity Survey
The WDJD-3A Multi-Function Digital DC Resistivity/IP Meter is an ideal instrument for individuals who require precise measurements with rapidity, dependability, and outstanding scalability. With years of design and manufacturing expertise, we have produced a product that satisfies the most recent user demands. Other multi-electrode resistivity software can process the WDJD-3A measured data, allowing for more convenient result interpretation.
Application
What is induced polarization surveying?
Induced polarization (IP) is the Earth’s capacity to hold an electric charge over time. IP measures the voltage decay curve after the injected current is shut off. The higher the IP, the longer over time the charge is held—IP decays over time, typically a few seconds but sometimes up to minutes, and will eventually disappear. IP is especially useful for mineral exploration applications.
Why is induced polarization surveying important?
The induced polarization method makes use of the capacitive action of the subsurface to locate zones where clay and other chargeable minerals are located within the host rock. With IP, you can tell very distinctly what is in the ground if it holds a charge because you end up with two maps—i.e., resistivity and IP—at the same time.
This is important for mineral exploration—identifying economically important minerals, including gold, copper, and silver. Early on, pyrite and massive sulfide minerals were deposited by hydrothermal fluids. These minerals have a huge IP signature, especially when disseminated as smaller grain in a rock matrix, which we can use when exploring for these minerals.
