Yukon Magnetic Geophysical Data Reprocessing for NTS 105K

Aurora Geosciences Ltd performed a review and standardization of publicly available digital magnetic geophysical data submitted with assessment reports. Data submitted prior to March 2015 were levelled and integrated with 1:250,000 scale compilations. The output includes four gridded PDF products and the original data is referenced in YGS Open File 2017-19.

Use Cases

• Mineral exploration targeting based on processed magnetic field derivatives.
• Geological mapping and structural interpretation based on reduced-to-pole magnetic data.
• Integrating historical assessment data with regional compilations for regional studies.

Strengths

• Data processed and levelled to a standardized 1:250,000 scale compilation.
• Includes four derivative products (residual total magnetic field, reduced to pole, vertical derivative, tilt derivative) for analysis.

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 temporal bias inherent to sources submitted before March 2015.
