IP, IP-Gradient, IP-VES, IP-Dipole-Dipole — Induced Polarization Method
Localizing mineralized zones, orebodies, and fault networks, determining target burial depths, and mapping water-bearing aquifers
Analyzing secondary electrical fields induced in sub-surface rock formations isolates conductive bodies within geological sections and characterizes their physical properties.
What Subsoil User Challenges Are Solved by the Induced Polarization Method?
01
Insufficient accuracy when localizing complex orebodies
Deploys IP profiling and its array modifications to precisely determine the geometry and burial depth of mineralized zones and orebodies — prior to drilling.
02
Missing deep-seated anomalies when relying solely on conventional methods
Applies the IP-Gradient (IP-SG) array to map geological structures down to depths of several hundred meters while maintaining clear vertical and lateral resolution across geo-sections.
03
Difficulties in resolving and interpreting complex structural fault networks
Utilizes the IP-Dipole-Dipole (IP-DP) method to pinpoint tectonic fault zones and associated mineralized controls using differential potential measurements.
04
Uncertainty in delineating aquifer boundaries and groundwater horizons
Leverages IP-VES sounding to isolate and outline groundwater-bearing strata and evaluate their electrophysical properties — without surface disruption or labor-intensive site prep.
How Does the Induced Polarization Process Work?
We deploy the Induced Polarization method to detect orebodies, mineralized domains, tectonic fault systems, and water-bearing aquifers.
The operational workflow consists of four structured phases:
- Array Setup — electrode arrays are deployed along specified surface profiles to feed excitation current into the ground. Array configurations are tailored to the chosen IP modification and specific campaign objectives;
- Current Injection & Response Recording — following current injection into the electrode system, secondary electrical fields generated in response to electromagnetic excitation are captured. These decay signals indicate the presence of conductive bodies, sulfide mineralization, or structural contacts;
- Method Selection Based on Objectives — IP serves as the baseline technique for mapping geo-electrical sections; IP-Gradient (IP-SG) targets deep-seated structural frameworks; IP-VES evaluates target burial depths; IP-Dipole-Dipole (IP-DP) localizes discrete, highly localized anomalies;
- Data Processing & Interpretation — inversion processing of geo-electrical cross-sections delineates key subsurface targets: orebodies, mineralized zones, tectonic fault systems, and aquifer horizons.
The Result: The client receives high-resolution geo-electrical sections and 3D inversion models, enabling accurate target localization, depth determination, and risk-mitigated exploration campaign planning.
Pinpointing Mineralized Domains — With Maximum Efficiency and Minimum Cost
The Induced Polarization method is deployed for geological structural diagnostics, mineralization assessment, and geo-electrical cross-section construction across all stages of mineral exploration.
