Magnetic Survey

At Retro Geoenergy, we provide high-resolution Magnetic Survey Services to support mineral exploration, oil & gas basin studies, groundwater investigations, and geotechnical projects. Magnetic surveys measure variations in the Earth’s magnetic field caused by subsurface rocks with contrasting magnetic properties—making them one of the most effective methods for mapping geology, structural features, and concealed mineral deposits.

Using advanced magnetometers, precise GPS positioning, and state-of-the-art processing techniques, we deliver accurate and reliable magnetic data tailored to exploration and engineering requirements.

• Mineral Exploration
– Identification of magnetite, chromite, iron ore, and other magnetic minerals.
– Mapping greenstone belts, banded iron formations (BIFs), and intrusive bodies.
– Structural mapping for base metals, gold, and diamond exploration.

• Oil & Gas Exploration
– Delineating sedimentary basins and basement depth.
– Identifying structural highs, fault zones, and rift systems.
– Supporting integrated gravity-magnetic-seismic interpretation.

• Groundwater & Hydrogeology
– Mapping basement configuration and aquifer geometry.
– Detecting fractures and structural controls on groundwater movement.

• Geotechnical & Engineering Studies
– Locating buried structures, pipelines, and metallic utilities.
– Supporting site investigations for dams, tunnels, bridges, and infrastructure projects.

• Regional & Tectonic Studies
– Mapping igneous intrusions, shear zones, and tectonic features.
– Contributing to crustal studies, geothermal exploration, and geohazard assessments.

• Ground Magnetic Surveys (detailed mapping with portable magnetometers)

• Airborne Magnetic Data Interpretation

• Total Magnetic Intensity (TMI) & Gradient Surveys

• Magnetic Data Processing & Interpretation:
