Upper Triassic Rock Stratigraphy at Hill 4308, Yukon

Geological data describes Upper Triassic carbonate, volcanic, and clastic rock deposition in the Whitehorse Trough forearc basin at Hill 4308, Yukon. The record details three distinct depositional stages involving lime sands, reefal carbonates, and clastic sedimentation. It compares this stratigraphy to the nearby Lime Peak location, noting differences in depositional continuity.

Use Cases

• Analyze the three-stage depositional sequence (lime sands, reefal carbonates, clastic deposition) to model paleoenvironmental changes.
• Compare stratigraphic sections and reefal carbonate structures between Hill 4308 and Lime Peak to assess local tectonic variation.
• Study the composition of reefal carbonates deposited on a volcanic high for insights into Triassic reef development in forearc basins.

Strengths

• Provides a detailed, stage-by-stage description of Upper Triassic rock deposition in a Mesozoic forearc basin.
• Includes a direct comparison to a similar geological formation (Lime Peak) located approximately 6 km away.

Limitations

• No structured data columns or sample data are provided; information is contained in descriptive text only.
• The dataset's format is HTML, which is not readily analyzable for quantitative modeling without manual extraction.
