Geochemical Zonation of the Emerald Lake Pluton in Yukon

Government of Yukon data details the Emerald Lake pluton, a concentrically-zoned intrusion comprising four distinct mapped phases. The dataset includes U-Pb and Ar-Ar dates indicating a statistically identical age of 93.1 Ma for major intrusive phases.

Use Cases

• Analyze the spatial distribution of augite syenite, hornblende quartz syenite, hornblende quartz monzonite, and biotite granite phases to model concentric zonation.
• Correlate U-Pb and Ar-Ar dates of 93.1 Ma across major intrusive phases to validate geochronological consistency.
• Map the occurrence of large miarolitic cavities along the southern margin of the intrusion relative to the four mapped phases.

Strengths

• Identifies four distinct mapped rock phases within the pluton.
• Provides statistically identical U-Pb and Ar-Ar dates of 93.1 Ma for major intrusive phases.

Limitations

• Data scope is limited to a single pluton in the Yukon Territory, reducing generalizability.
• Original data format is HTML, which may require extraction and structuring for quantitative analysis.
