Selwyn Basin ZTEM Geophysical Survey Data and Maps

In 2008, Exploration Syndicate Inc. contracted Geotech Inc. to fly a regional-scale ZTEM survey covering a 25,000 km2 area in the Selwyn basin. The Yukon Geological Survey purchased the data in 2013, and Condor Consulting Inc. later processed it to generate maps, gridded data, and a report. The dataset includes raw survey data, acquisition reports, processed grids, and maps in PDF and TIFF formats.

Use Cases

• Analyze regional geological structures based on ZTEM geophysical data.
• Generate subsurface interpretation maps based on the provided gridded data and reports.
• Correlate geophysical anomalies with known mineral deposits in the survey area.
• Use the raw survey data for custom geophysical processing and modeling.

Strengths

• Covers a large 25,000 km2 survey area with 1 km line spacing.
• Includes multiple data products: raw data, processed grids, maps, and interpretation reports.
• Publicly distributed under the OGL-CA-2.0 license after approval in May 2013.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• File sizes are large, which may complicate downloading and handling.
• Row count and specific data volume are unknown, which may limit suitability assessment.
