A 2026 study by the Government of Yukon inverted 321 extremely low frequency electromagnetic, 33 audiomagnetotelluric, and 51 magnetotelluric stations to map subsurface electrical structure to 8 km depth in the Burwash Landing region. The resulting model reveals conductive structures associated with faults and intrusions, interpreted as fluid pathways and potential heat sources for a geothermal system.
Use Cases
- Model subsurface fluid pathways based on conductive structures associated with the Denali and Bock's Creek faults.
- Identify potential geothermal heat sources based on conductive bodies linked to intermediate to mafic intrusions.
- Map the geometry of a geothermal system based on three-dimensional inversion of passive electromagnetic data.
- Assess geothermal potential in a region based on mapped vertical conductive structures and interpreted releasing bends.
Strengths
- Integrates three distinct passive electromagnetic datasets totaling 405 stations.
- Provides subsurface electrical structure mapping to a depth of 8 kilometers.
- Model reveals specific conductive structures associated with named geological features.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data format is HTML; conversion may be required for analysis.
