Magnetic Surveying measures variations in the Earth’s magnetic field generated by differences in sub-surface rock magnetic susceptability. Applications of magnetic surveys have a broad range of applications including geological, civil and archaeological.

Identifiable Features

The use of Magnetic Geophysical surveys is a widely used technique due to its speed of acquisition and lower cost. Magnetic Surveys can provide;

• Palaeochannels containing tertiary basalt can be identified, extent mapped and an estimate of thickness obtained.
• Delineate dyke, sill & massive intrusives.
• Large scale basement fracture and fault systems that alter the basin floor can be mapped.
• Smaller scale fracture and fault systems that cross magnetically inductive bodies, such as sills can be identified.
• Magnetically inductive ore bodies can be easily identified.

GeoConsult Acquisition

• Good start to exploration; low impact – easier land access, use of existing infrastructure,      small team, relatively low cost & quick.
• Provision of all field equipment, personnel and procedures to match the scale of the target.
• Acquisition process from survey design, trial survey’s to field data collection processing & storage.
• Latitude/Inclination adjustments to the geomagnetic field.
• Di-urnal variation, geomagnetic, elevation & Terrain corrections.
• Geophysical corrections and modelling.
• Can be run in conjunction with gravity and TSIM surveying to increase interpretation reliability.
• Professional reporting on nature of recorded magnetic anomalies.

GeoConsult provides a complete service from survey planning and design, access to the survey equipment, data acquisition, interpretation and professional reporting.
