Geological Setting of Emeralds at Regal Ridge in Yukon

In 1998, a new occurrence of emeralds was discovered in the Finlayson Lake area, southeastern Yukon. The dataset describes the geological setting, including the host rocks, alteration veins, and inferred sill structure. It was published by the Government of Yukon and last updated in April 2026.

Use Cases

• Identify potential emerald exploration targets based on described geological criteria.
• Study the relationship between emerald occurrence and specific rock types like meta-basalt and serpentinized meta-plutonic rocks.
• Analyze the spatial distribution of mineral veins relative to synvolcanic faults mentioned in the description.
• Model emerald formation processes based on the inferred comagmatic sill structure.

Strengths

• Dataset is based on a specific discovery event in 1998, providing a concrete case study.
• Description details specific geological units (Upper Devonian Fire Lake unit) and rock compositions (boninitic meta-basalt).
• Last updated date (2026-04-17) is provided, indicating recent metadata maintenance.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to a single location in southeastern Yukon.
• The actual data files (HTML, PDF) may contain unstructured text and figures rather than structured tabular data.
