Aeromagnetic survey data processed to show the first vertical derivative of the magnetic field. The data was acquired by Goldak Airborne Surveys from May 16 to July 1, 2009, using a cesium vapour magnetometer mounted on a Piper Navajo aircraft. The survey covered parts of NTS 115O/1, 115O/2, and 115O/3 in Yukon, with a nominal terrain clearance of 150 meters.
Use Cases
- Identify geological structures and fault lines based on magnetic gradient anomalies.
- Support mineral exploration targeting by mapping subsurface magnetic variations.
- Integrate with other geophysical data for regional geological interpretation.
- Create enhanced magnetic field maps for academic research in geophysics.
Strengths
- Survey conducted with a split-beam cesium vapour magnetometer, a precise instrument.
- Specific flight parameters are documented, including a 150-meter terrain clearance and 400-meter traverse line spacing.
- Data has a defined temporal coverage from May 16 to July 1, 2009.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the specific survey area in Yukon.
