Upper Devonian Imperial Formation Stratigraphic Sections from Tetlit Creek, Yukon

Field notes document stratigraphic sections measured in the Upper Devonian Imperial Formation along Tetlit Creek in the east Richardson Mountains, Yukon, during summer 2008. The Government of Yukon collected samples for palynological, geochemical, and vitrinite reflectance analyses to determine age and source rock potential. The strata are described as overmature with respect to hydrocarbon generation.

Use Cases

• Modeling stratigraphic architecture based on lithologic variation between mudstone/siltstone and sandstone units.
• Assessing hydrocarbon source rock potential based on Rock Eval/TOC and vitrinite reflectance data.
• Determining depositional age of Devonian strata using palynological analyses.
• Evaluating thermal maturity of sedimentary rocks using Thermal Alteration Index (T.A.I.) data.

Strengths

• Data is based on detailed stratigraphic sections measured in outcrop during a dedicated field season.
• Analyses include multiple methods: palynology, geochemistry (Rock Eval/TOC), and vitrinite reflectance.
• The geographic focus is a specific, well-exposed location (Tetlit Creek, NTS map sheet 106L).

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description states the organic matter present is not favourable for source rock potential, limiting applicability for hydrocarbon exploration.
