Wrangell Volcanic Belt Magmatism Composition and Temporal Trends

Geological data describes the origin and setting of anomalous arc magmatism in the Wrangell Volcanic Belt, Southwest Yukon. The dataset likely contains compositional and temporal trends for volcanic stratigraphy spanning 17.3 to 6.5 million years in the St. Clare Creek field. It was published by the Government of Yukon on the open_canada platform.

Use Cases

• Modeling mantle diapir melting processes based on descriptions of alkaline shield volcano formation
• Analyzing temporal-chemical relationships based on trends in FeO/MgO, Na+K/Si, NB/Zr/Y, and Rb/Zr ratios
• Studying the effects of oblique plate convergence on magmatic migration over 17.3 million years
• Investigating fractional crystallization and magma mixing processes in near-surface environments

Strengths

• The description provides a detailed geological model spanning 17.3 million years
• Compositional-temporal trends are described for a specific four-stage stratigraphy in the St. Clare Creek field (17.3-6.5 Ma)
• The dataset is associated with a specific government source (Government of Yukon) and has a defined license (OGL-CA-2.0)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count and dataset size are unknown, which may limit suitability assessment
• The data format is limited to HTML and PDF, which may not be readily analyzable
