Geophysical Transect of Northern Yukon Foldbelt and Anticlinorium

A 250-kilometer east-west geological and geophysical transect spans the Eagle Plains foldbelt and Richardson Mountains anticlinorium in northern Yukon and western Northwest Territories. It incorporates reprocessed industry seismic reflection profiles, regional gravity data, and drill hole information. The transect models a contractional pop-up structure with an estimated 33 kilometers of horizontal displacement.

Use Cases

• Interpret the structure of the Richardson Mountains Anticlinorium using reprocessed seismic reflection profiles and gravity data.
• Model the 33 km of horizontal displacement for the pop-up structure using integrated geophysical and drill hole data.
• Analyze the relationship between the Eagle Plains foldbelt and the anticlinorium using the 250 km transect's geological data.

Strengths

• Transect covers a 250-kilometer geological cross-section.
• Integrates multiple data types: seismic profiles, gravity data, and drill hole information.
• Provides a structural interpretation with quantified displacement estimates of about 33 kilometers.

Limitations

• Data format is HTML, which is not a standard, machine-readable format for geospatial or tabular analysis.
• Sample data and specific columnar structure are unavailable, limiting immediate analytical use.
• The dataset's completeness and granularity for quantitative modeling are unclear from the description.
