Gemstone Deposit Exploration Criteria Applied to Yukon Geology

A report from the Government of Yukon focuses on exploration criteria for valuable gemstones like ruby, sapphire, emerald, and minerals found in pegmatites. It provides background information, physical characteristics, deposit geology, and specific guidelines for exploration. The report applies these criteria to Yukon geology and was last updated on April 17, 2026.

Use Cases

• Identify potential gemstone deposit locations based on geological criteria described for ruby, sapphire, and emerald.
• Study the genesis and characteristics of pegmatite-hosted gem minerals like aquamarine, tourmaline, and topaz.
• Apply the exploration guidelines summarized for each gem deposit type to regional geological assessments.
• Reference the compiled background information on physical and chemical characteristics of covered gem minerals.

Strengths

• Report covers a selection of globally valuable gemstones including ruby, sapphire, emerald, and tanzanite.
• Includes a dedicated chapter on pegmatites and their gem minerals, and another on topaz rhyolite deposits.
• Provides specific application of exploration criteria to Yukon geology in Chapter Nine.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Exploration criteria for opal, nephrite jade, jadeite jade, zircon, lapis lazuli, and rhodonite are explicitly stated as beyond the report's scope.
