Electrical and Resistivity Surveys

Induced Polarization Survey

It is commonly paired with resistivity imaging where projects need better discrimination of potential mineralized or clay-rich zones.

Definition

What this method is

Induced polarization measures delayed electrical response in the ground to help distinguish chargeable materials and refine subsurface interpretation.

It is commonly paired with resistivity imaging where projects need better discrimination of potential mineralized or clay-rich zones.

How It Works

From field measurement to interpreted model

  1. 1Current is introduced through electrodes and both resistivity and chargeability responses are measured.
  2. 2Field data are processed and inverted to produce interpreted chargeability and resistivity sections.
  3. 3Interpretation is integrated with geology and project targets to prioritize follow-up validation.

When to Use

Best-fit conditions for this method

  • Mineral exploration and target prioritization programs
  • Projects that require chargeability context in addition to resistivity
  • Integrated groundwater or geohazard investigations with conductive contrasts

What It Can Help Identify

Subsurface features and signals

  • Chargeability anomalies of potential exploration interest
  • Zones where resistivity-only interpretation is ambiguous
  • Priority targets for drilling or direct investigation

Deliverables

What you receive

  • Chargeability and resistivity interpretation sections
  • Acquisition and processing summary
  • Target-ranking recommendations

Typical Outputs

What the data looks like

  • Chargeability profile
  • Integrated IP-ERT section
  • Target priority map

Applications

Common applications in the Philippines

Mining and exploration support

Integrated resistivity and IP investigations

Large-area subsurface screening programs

Method Limitations

What this method cannot do alone

  • Interpretation quality depends on electrode contact, line geometry, and site noise control.
  • Anomalies are interpretive indicators and need direct validation for critical decisions.
  • Acquisition can be slower where access and grounding conditions are difficult.

Geophysical results are interpreted models based on measured physical property contrasts. Results should be correlated with boreholes, test pits, drilling, geological mapping, laboratory data, or other direct investigation methods where required.

FAQs

Frequently Asked Questions

What is the main advantage of induced polarization surveys?

IP adds chargeability information that can improve discrimination of targets compared with resistivity-only interpretation.

Can IP data be used without resistivity?

IP is strongest when interpreted with resistivity and geology, especially in exploration and complex subsurface settings.
