Aeromagnetic survey of the central Slave craton area, Northwest Territories
The aeromagnetic data can illustrate the presence of certain rock types, anomalous zones and structures in the Earth’s upper crust. To achieve this objective, a high-resolution aeromagnetic data survey was performed with specifications such as nominal traverse line spacing 100 m with east-west direction and control lines spacing 600 m with north-south direction. The nominal aircraft terrain clearance was 60 m with drape flying. A total of 87,696 line-km data was acquired, covering approximately 7,500 km2.
Previous to this study, only low-resolution regional aeromagnetic data was publically available, and this new high-resolution aeromagnetic data can be used by multiple stakeholders to enhance geoscience knowledge, promote mineral exploration, and inform land use planning decisions. This survey is located over an under-explored area between active diamond mines, where a number of magnetic anomalies may suggest diamond potential.
EON Geoscience Inc. (EON) carried out this fixed-wing aircraft aeromagnetic survey using three aircraft equipped with cesium vapour magnetometers located in the tail booms of each aircraft. High-resolution data products were provided by EON in Geosoft’s database and grids along with Geotiffs and PDF formats.
