Kluane Metamorphic Assemblage Rocks in Southwest Yukon

A 150-km-long belt of mica-quartz schist and olivine serpentinites wedged between the Yukon-Tanana Terrane and the Insular Superterrane in southwest Yukon. The dataset likely contains geological and geospatial data on these 'Alpine-type' ultramafic rocks, interpreted as fragments of oceanic crust from a Late Cretaceous back-arc basin. It is provided by the Government of Yukon on the open_canada platform.

Use Cases

• Analyze tectonic emplacement patterns based on the described foliation and shear sense orientation
• Study the formation of oceanic crust fragments based on oxygen isotope analyses mentioned in the description
• Map the distribution of ultramafic bodies and schist based on the described 150-km-long belt
• Model Late Cretaceous back-arc basin subduction and accretionary processes based on the tectonic interpretation

Strengths

• Describes a specific 150-km-long geological belt
• Includes interpretation based on oxygen isotope analyses
• Provides a tectonic model for Late Cretaceous events

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to open_canada
