Aurora Geosciences Ltd reprocessed publicly available digital magnetic geophysical data from assessment reports submitted to the Government of Yukon. The work integrated individual reports with 1:250,000 scale compilations and produced four standardized gridded products. Data submitted prior to March 2015 were considered for this reprocessing.
Use Cases
- Analyze subsurface geological structures based on the residual total magnetic field grid.
- Interpret magnetic anomalies for mineral exploration based on the reduced-to-pole grid.
- Enhance edge detection of geological features based on the vertical derivative grid.
- Map subtle magnetic gradients based on the tilt derivative grid.
Strengths
- Data integrated with standardized 1:250,000 scale compilations.
- Four derivative grids (residual, reduced-to-pole, vertical derivative, tilt derivative) provide multiple analytical perspectives.
- Original source data is documented in YGS Open File 2017-13.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data freshness should be verified as the reprocessing used reports submitted before March 2015.
