Bedrock mapping data highlights two exceptionally well preserved, undeformed and unmetamorphosed volcanosedimentary sequences of Late Paleozoic age in the southern Semenof Hills, central Yukon. The sequences include fragmental volcanic rocks, basaltic lava flows, volcanic conglomerate, and fossiliferous Upper Carboniferous limestone. The dataset is provided by the Government of Yukon and was last updated in April 2026.
Use Cases
- Analyze stratigraphic sequences based on described volcanic and sedimentary layers.
- Study Late Paleozoic volcanic preservation based on the described undeformed sequences.
- Map geological fault contacts based on the described faulted contact between sequences.
- Identify fossiliferous limestone deposits based on the Upper Carboniferous limestone unit.
Strengths
- Describes exceptionally well preserved, undeformed sequences.
- Includes thickness estimates for units, such as a 2- to 3-km-thick fragmental volcanic layer.
- Specifies the presence of fossiliferous Upper Carboniferous limestone.
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 open_canada.
