Cretaceous Granitoid O-S Isotope Compositions in Yukon and Northwest Territories

Stable isotopic compositions of Cretaceous granitoids emplaced between 109 and 90 million years ago. The dataset likely contains oxygen and sulfur isotope measurements from plutonic suites in the Cassiar Platform and Selwyn Basin. It was published by the Government of Yukon and last updated in April 2026.

Use Cases

• Modeling magma source regions based on stable isotopic compositions.
• Comparing isotopic signatures between different plutonic suites (Cassiar, Hyland, Tay River, Tungsten, Mayo, Tombstone).
• Investigating crustal contamination or mantle contributions in granitoid formation.
• Correlating isotopic data with regional geological frameworks of the Cassiar Platform and Selwyn Basin.

Strengths

• Specific temporal coverage of Cretaceous granitoids (109-90 Ma).
• Regional focus on a defined geological area (Cassiar Platform and Selwyn Basin).
• Published by an authoritative government organization (Government of Yukon).

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 study region.
