Residual Total Magnetic Field Map, Northern Stevenson Ridge Yukon

Yukon, Canada, specifically the Northern Stevenson Ridge area within NTS sheets 115O/1, 115O/2, and part of 115O/3. This map of the residual total magnetic field was derived from an aeromagnetic survey flown by Goldak Airborne Surveys between May 16 and July 1, 2009. Data were recorded using a cesium vapour magnetometer mounted on a Piper Navajo aircraft flying at a nominal terrain clearance of 150 meters.

Use Cases

• Identify geological structures and lithological boundaries based on magnetic field variations.
• Support mineral exploration targeting by mapping magnetic anomalies associated with ore deposits.
• Create derivative geophysical models for subsurface interpretation based on the residual magnetic field data.
• Integrate with other geospatial datasets for regional geological analysis of the Yukon.

Strengths

• Survey conducted with specific, documented parameters: 400 m traverse line spacing and 2400 m control line spacing.
• Data acquisition details are precise, including the aircraft type (Piper Navajo), sensor (split-beam cesium vapour magnetometer), and nominal flight height (150 m terrain clearance).
• Clear temporal scope: data collected between May 16, 2009 and 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 for large-scale statistical analysis.
• Data may reflect geographic/temporal/source bias inherent to the specific survey area and time period.
