Curie Point Depth Grid and Contours for Yukon Territory

Yukon's subsurface heat flow is analyzed through Curie point depth mapping using public aeromagnetic data. The study demarcates 95% of the territory into regions of shallow or deep CPD, corresponding to higher or lower heat flow. Results are presented as a gridded dataset with 1 km interval contours.

Use Cases

• Correlate shallow CPD grid values with elevated near-surface heat flow measurements to validate geothermal potential models.
• Analyze the spatial distribution of CPD contours to identify geological boundaries between Cordillera and continental platform rocks.
• Combine CPD grid data with heat generation and sediment thickness estimates to model prospective regions for subsurface heat.
• Assess methodological discrepancies by comparing CPD estimates derived from 200 km and 300 km window size analyses.

Strengths

• Covers 95% of Yukon's territory with demarcated Curie point depth regions.
• Provides data in two formats (ESRI REST, HTML) for different analytical tools.
• Results are grounded in comparison with Yukon-specific crustal geotherms and near-surface heat flow measurements.

Limitations

• The study notes CPD estimates for south-central Yukon may be systematically too deep by 2 to 12 km due to magnetization distribution.
• Dataset structure (rows, columns, sample data) is unspecified, complicating immediate programmatic use.
• Relies on public domain aeromagnetic data which may have inherent resolution or coverage limitations.
