Principles of High-Power Induced Polarization (IP) Technology
High-power induced polarization technology is a geophysical exploration method widely used in mineral resource surveys. It utilizes high-frequency electrical currents to generate an electromagnetic field underground. By analyzing variations in the electromagnetic field, mineral deposits can be detected. During exploration, parameters such as current frequency, amplitude, duration, and electrode configuration are controlled to capture distinct electromagnetic field characteristics, enabling the estimation of underground mineral reserves.
Technical Advantages
Compared to traditional geophysical exploration methods, high-power IP technology offers the following advantages:
- High Sensitivity: Detects subtle electromagnetic field variations in mineral deposits, enabling effective identification of weak metallic ores.
- Non-Invasive: Conducts surface surveys without excavation, overcoming challenges faced by conventional geological methods.
- High Efficiency: Delivers rapid, accurate, and large-scale exploration, particularly effective for extensive mineral deposit surveys.

FAQ
① In SI, it is m·s-2, and one percent of it is the international unit abbreviation g.u.;
② Conversion between SI and CGS: 1g.u.=10-1 mGal
Gravitational field: The space around the earth with gravity is called the gravitational field.
Gravitational potential: The gravitational potential W in the gravitational field is equal to the work done by a particle of unit mass moving from infinity to that point.
① The normal gravity field of the earth: Assuming that the earth is a rotating ellipsoid (reference plane), the surface is glossy, the internal density is uniform, or it is distributed in concentric layers, the density of each layer is uniform, and the deviation of the shape of the ellipsoid from the geoid is very small, then the gravity field generated by the earth is the normal gravity field.
② The normal gravity value is only related to the latitude, the smallest at the equator and the largest at the poles, with a difference of about 50,000 g.u.; the rate of change of the normal gravity value with latitude is the largest at 45° latitude, and zero at the equator and the poles; the normal gravity value decreases with increasing altitude, and its rate of change is -3.086 g.u.. The main feature of the long-term change is the "westward drift" of the geomagnetic elements, both the dipole field and the non-dipole field drift westward, and have a global nature.
The gravitational field strength is equal to the gravitational acceleration in both numerical and dimensional terms, and the two are in the same direction. In gravity exploration, all references to gravity refer to gravitational acceleration. The gravitational field strength at a point in space is equal to the gravitational acceleration at that point.
Gravity exploration is an exploration method that is based on the density difference of rocks and ores. Since density difference will cause local changes in the normal gravity field of the earth (i.e. gravity anomaly), it is used to solve geological problems by observing and studying gravity anomalies.
