Skukum Area Rhyolite Intrusives Geochemical Data, Yukon

Geochemical and petrological data for nine high-level rhyolite to dacite intrusives in the Skukum area, 58 km south-southwest of Whitehorse, Yukon. The dataset includes chemical analyses supporting a cogenetic origin, with evidence from major oxides, trace elements, and rare earth elements. Data was published by the Government of Yukon and last updated on 2026-04-17.

Use Cases

• Modeling magmatic differentiation trends based on major oxide chemistry (SiO2, CaO, MgO).
• Investigating fractionating mineral phases using trace element plots (Sr, Ba vs. Al2O3).
• Analyzing rare earth element behavior to identify controlling accessory phases like monazite or fluorite.
• Comparing petrogenetic processes between the Skukum intrusives and the Bennett Lake complex using Zr and TiO2 concentrations.

Strengths

• Chemical data includes major oxides, trace elements, and rare earth elements for nine distinct intrusives.
• Petrographic and field evidence (e.g., breccia pipes, miarolitic cavities) supports the high-level emplacement interpretation.
• Data is published under the OGL-CA-2.0 license, facilitating open use and redistribution.

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 area in the Yukon.
