A 2026 update to the geological map of the Mount Nansen area in Yukon, Canada, compiled by the Government of Yukon. The revision incorporates new U-Pb zircon crystallization ages for Cretaceous magmatic rocks, including the Kelly and Cyprus porphyries. This map likely contains geospatial data representing bedrock geology for mineral exploration.
Use Cases
- Update geological models based on new U-Pb zircon ages for Cretaceous rocks
- Identify potential mineral deposits based on the geology of the Kelly and Cyprus porphyries
- Correlate rock units with the Whitehorse and Minto magmatic suites using crystallization ages
- Support mineral exploration planning in the Mount Nansen area using bedrock geology data
Strengths
- Provides updated crystallization ages for key rock units, including ca. 78 Ma for Kelly porphyry
- Compiled and re-interpreted by the authoritative Government of Yukon
- Last updated on 2026-04-17, indicating recent revision
