A 20-meter-thick, moderately dipping quartzite interval northeast of Mayo Lake hosts low to moderate levels of widely distributed gold. The altered sandstone unit is highly porous and friable due to secondary leaching, can be traced along strike for 4 km, and contains abundant, regular, steep, northeast-striking vuggy quartz veins. This dataset from the Government of Yukon describes characteristics of sediment-hosted disseminated gold deposits.
Use Cases
- Mapping hydrothermal alteration zones based on described bleached white appearance and pervasive sericite/illite development.
- Analyzing stratabound mineralization potential based on the 4 km strike length and stratabound vuggy quartz veins.
- Modeling pore fluid pressure and hydrofracturing based on the described in-situ hydrofracturing mechanism.
- Identifying sediment-hosted gold exploration targets based on the distinct texture and appearance of the altered Mississippian Keno Hill Quartzite.
Strengths
- Describes a spatially extensive geological feature with a 4 km strike length.
- Provides detailed mineralogical and textural characteristics, including pervasive alteration within a 20m-thick interval.
- Identifies a specific deposit type (sediment-hosted disseminated gold) with supporting alteration evidence.
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 Yukon region.
