Gravity Survey Services
High-resolution density mapping for smarter, more efficient exploration.
Gravity surveys are one of the most reliable and cost-effective geophysical tools for mapping subsurface density variations, identifying major structures, and detecting dense ore bodies. Our gravity survey services help exploration teams reduce uncertainty, improve drill targeting, and gain a clearer understanding of the geology beneath their project.
Rangefront provides end-to-end gravity survey solutionsfrom survey design and field acquisition to processing, modeling, and interpretation.
Why Choose Gravity Surveys?
Gravity surveys measure subtle changes in the Earth’s gravitational field caused by differences in rock density. These variations reveal major geological features that are critical to mineral exploration.
Gravity surveys are ideal for:
- Identifying dense ore bodies (sulfides, iron ore, ultramafics, skarns)
-
Defining basin architecture and depth to basement
-
Locating intrusive bodies and lithological boundaries
-
Targeting beneath cover, volcanic sequences, or conductive overburden
- Mapping faults, shear zones, and structural traps
Because gravity is unaffected by conductivity or cultural noise, it performs exceptionally well in environments where EM or IP surveys may struggle.
Our Gravity Survey Services
We offer a full suite of ground and airborne gravity survey services designed to support exploration programs at any stage.
Survey Design & Planning
A strong survey begins with strategic planning. Our team works with you to determine:
-
Optimal station spacing
-
Base station setup
-
Access strategy and terrain considerations
-
Elevation control options
-
Integration with existing geophysical or geological datasets
We tailor every survey to your deposit type, exploration stage, and budget.
High-Resolution Field Acquisition
Our field crews are trained and equipped to operate in rugged North American terrains—from desert basins to alpine ridges.
We provide:
-
Ground gravity acquisition using high-precision gravimeters
-
Differential GPS for accurate elevations
-
Daily instrument drift checks
-
Repeat stations for quality control
-
Safe and efficient terrain access
Your project is supported by certified, field-ready technicians with deep experience in mineral exploration settings.
Data Processing & Corrections
Clean data is essential for meaningful interpretation. We apply all standard corrections, including:
-
Latitude and free-air corrections
-
Bouguer and terrain corrections
-
Earth tide adjustments
-
Instrument drift corrections
-
Elevation and topographic refinement
You receive high-quality Bouguer anomaly data ready for interpretation or integration into 2D/3D models.
Interpretation, Modeling & Deliverables
Our geophysicists deliver detailed analysis aligned with your project goals:
Deliverables include:
-
Gravity anomaly maps (Bouguer, free-air, residual grids)
-
Derivative and gradient maps
-
Structural and lithological interpretations
-
Integrated models (gravity + mag + IP/EM + geology)
-
2D/3D inversions
-
Targeting recommendations to guide drill placement
Every interpretation package is exploration-focused, decision-ready, and designed to reduce drilling risk.
When Gravity Surveys Provide the Most Value
Gravity surveys are the right choice when you need to:
-
Explore beneath deep cover or complex overburden
-
Understand basin geometry or depth to basement
-
Model intrusive systems associated with Ni-Cu-PGE or porphyry deposits
-
Target dense bodies such as VMS, skarns, or iron formations
-
Map key structures controlling mineralization
-
Strengthen a 3D geological model for NI 43-101 or S-K 1300 reporting
If density contrast is important in your geological environment, gravity data is often essential.
