A two square mile stock of biotite quartz monzonite forms the core of Spearhead Mountain in the Yukon Territory. Trend surfaces from first to third order were established from modal data for plagioclase, orthoclase, quartz, and total mafic minerals, along with specific gravity values. This thesis is available online from the Government of Yukon.
Use Cases
- Modeling mineral distribution patterns based on modal data for quartz, mafic minerals, and specific gravity.
- Analyzing the effects of silica assimilation on magma composition based on described contamination processes.
- Mapping circular zonation patterns in intrusive rocks based on contoured modal data and trend surfaces.
Strengths
- Focuses on a specific two square mile geological stock.
- Includes detailed modal data for multiple minerals and specific gravity values.
- Analysis includes trend surfaces up to the third order.
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 a single location study.
