Yukon Magnetic Geophysical Data Reprocessing for NTS 105J

Data submitted prior to March 2015 were considered for this reprocessing project. Aurora Geosciences Ltd performed a review and integration of publicly available digital magnetic data from assessment reports, levelling them with 1:250,000 compilations. The Government of Yukon produced four gridded PDFs, including residual total magnetic field and derivative products.

Use Cases

• Mineral exploration targeting based on processed magnetic field anomalies.
• Regional geological mapping based on integrated magnetic compilations.
• Geophysical research based on standardized magnetic products like reduced-to-pole grids.
• Assessment of subsurface structures based on vertical and tilt derivative maps.

Strengths

• Data integrated from multiple assessment reports into standardized compilations.
• Four distinct processed magnetic products (residual, reduced to pole, vertical derivative, tilt derivative) are available.
• Data is tied to a specific 1:250,000 map scale (NTS 105J).

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 underlying assessment reports are from before March 2015.
