The Dezadeash Range and adjacent northern Coast Mountains in southwestern Yukon are the focus of this geological dataset. It describes the intrusion of granodiorite into metasedimentary rocks and the distribution of schist and gneiss assemblages. The dataset presents a re-examination of a terrane boundary location based on recent petrographic studies.
Use Cases
- Mapping terrane boundaries based on descriptions of rock assemblages and fabric changes.
- Studying metamorphic grade progression based on the reported southeastward increase.
- Correlating regional metamorphic rocks based on the described Kluane and Nisling Assemblage distributions.
- Analyzing the absence of specific continental margin rocks (marble, quartzite) for geological interpretation.
Strengths
- Focuses on a specific geological region (Dezadeash Range and northern Coast Mountains, southwestern Yukon).
- Includes a re-examination of a key geological feature (terrane boundary) with updated location.
- Provides detailed petrographic descriptions of rock types (granodiorite, schist, gneiss).
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 the specific Yukon study area.
