Gold-rich polymetallic vein and gold-copper porphyry deposits occur along a northwesterly trend across the southern Dawson Range. The dataset likely contains geochemical and lithological data from the Government of Yukon, focusing on volcanic rocks from the Mt. Nansen and Carmacks Groups. Radiometric age determinations constrain the Carmacks Group to approximately 70 Ma and the Mt. Nansen Group to approximately 105 Ma.
Use Cases
- Modeling hydrothermal alteration processes based on descriptions of sericite and clay mineral replacement.
- Analyzing geochemical trends in ore metals (Pb, Zn, Cu, As, Sb, Au) based on their reported depletion or introduction.
- Distinguishing volcanic suites based on potassium (K) content, as described for the high-K calc-alkaline Mt. Nansen Group and shoshonitic Carmacks Group.
- Investigating the temporal relationship between mineralization and dyke emplacement based on K/Ar date ranges from 94 to 61 Ma.
Strengths
- Data is associated with specific geological groups and age constraints (Carmacks Group ~70 Ma, Mt. Nansen Group ~105 Ma).
- Description details specific geochemical processes, such as depletion of Na and mobilization of Pb, Zn, and Cu.
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 study area in the Yukon.
