Geology and Geochemistry of the Teslin Crossing Pluton, Yukon

A geological and geochemical dataset for the Teslin Crossing Pluton, a small (~75 km²) Early Jurassic alkalic plutonic complex in Yukon's Stikine Terrane. The data includes rock descriptions, mineralogy, and geochemical analyses (e.g., 3.1-3.4% K2O, 60-68% SiO2) relevant to gold-rich porphyry copper mineralization. It is published by the Government of Yukon on the open_canada platform.

Use Cases

• Identify geological targets for gold-rich porphyry copper mineralization based on described rock types and alteration zones.
• Analyze geochemical signatures (e.g., K2O, SiO2 content) to classify and compare alkalic plutonic complexes.
• Correlate pluton emplacement timing using the provided age constraints (Pliensbachian to Aalenian fossils, ~175 Ma U-Pb date).
• Map lithological units and intrusive phases (border phase, central phase, sills, dykes) for regional geological modeling.

Strengths

• Includes specific geochemical ranges (e.g., 3.1-3.4% K2O, 60-68% SiO2) and mineralogical details (e.g., magnetite up to 5%).
• Provides spatial context with a defined area (~75 km²) and geographical location (Stikine Terrane, Yukon).
• Offers multiple age constraints for the pluton, including fossil evidence and radiometric dates.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data freshness should be verified; last metadata update was 2026-04-17 16:08:03.566612.
