Petrological Study of Ultramafic Rocks Across Yukon, Alaska, and British Columbia

Petrological data from nine site locations across Yukon, Alaska, and British Columbia. The dataset likely contains rock type classifications and geological interpretations for ultramafic rocks from the Cache Creek and Slide Mountain terranes. It was published by the Government of Yukon and last updated on April 17, 2026.

Use Cases

• Compare rock compositions between Cache Creek and Slide Mountain terranes based on the described prevalence of harzburgite and lherzolite.
• Analyze the geological settings of serpentinized harzburgite across nine site locations mentioned in the description.
• Study tectonic emplacement of oceanic assemblages based on the described terrane relationships.
• Investigate the lower layers of dismembered ophiolite complexes based on the interpretation provided for the ultramafic rocks.

Strengths

• Data covers nine specific site locations across Yukon, Alaska, and British Columbia.
• Distinguishes rock types (harzburgite and lherzolite) and their associations with specific terranes.
• Last updated on April 17, 2026, indicating recent maintenance.

Limitations

• Row count and column-level documentation are unknown, limiting suitability assessment.
• Data may reflect geographic bias inherent to the specific study locations.
• Description metadata is limited; actual data quality requires manual inspection after download.
