Field and petrographic data from sediment-hosted barite occurrences in the MacMillan Pass district of Yukon. The dataset likely contains sample analyses from the Walt, Tyrala, and Hess occurrences, examining textures and geochemistry. It was published by the Government of Yukon and last updated on April 17, 2026.
Use Cases
- Modeling sedimentary-exhalative (SEDEX) deposit formation based on described barite textures.
- Analyzing the relationship between barite and base metal sulphide mineralization based on the geological interpretation.
- Mapping mineral occurrence distribution within the Devonian Portrait Lake and Ordovician-Silurian Road River Groups.
- Comparing synsedimentary versus diagenetic barite deposition based on the variety of textures encountered.
Strengths
- Data is associated with specific, named geological occurrences (Walt, Tyrala, Hess).
- Study examines mineralization across two distinct geological groups (Portrait Lake Formation and Road River Group).
- Last update timestamp is precisely recorded (2026-04-17 15:46:01.104214).
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 Yukon district studied.
Provenance
