First Vertical Derivative of the Magnetic Field for the Marsh Lake Area, Yukon

Aeromagnetic survey data collected by Geo Data Solutions GDS Inc. from January 12 to March 16, 2018. The data were recorded using split-beam cesium vapour magnetometers mounted on a Beechcraft King Air and a Piper Navajo aircraft flying at a nominal terrain clearance of 150 meters. Traverse lines were spaced 400 meters apart and oriented N45°E, with orthogonal control lines spaced 2400 meters apart.

Use Cases

• Geological mapping based on magnetic field anomalies
• Mineral exploration targeting based on subsurface magnetic structures
• Regional geophysical analysis based on high-resolution aeromagnetic data
• Integrating magnetic data with other geospatial datasets for geological modeling

Strengths

• Survey conducted with specific split-beam cesium vapour magnetometers
• Nominal flight terrain clearance of 150 meters for high-resolution data
• Precise survey period from January 12 to March 16, 2018
• Defined traverse line spacing of 400 meters and control line spacing of 2400 meters

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/temporal bias inherent to open_canada
