Geology of Northwest Whitehorse Yukon with Granitic Weathering Study

Government of Yukon provides a geological thesis describing rock formations and weathering processes in the northwest quarter of the Whitehorse map area. The study analyzes Upper Triassic to Tertiary rock sequences, including the Lewes River and Laberge series, and investigates mineralogy, texture, and porosity of weathered granitic rocks. Specific row and column counts are unavailable for this document-based dataset.

Use Cases

• Analyze the relationship between mineralogy, texture, and porosity features of granitic rocks and their observed weathering susceptibility.
• Map the stratigraphic sequence and unconformities between Upper Triassic Lewes River series, Jurassic Laberge series, and Hutshi group volcanics.
• Study the distribution and characteristics of Tertiary basalt flows exposed in the southern part of the Whitehorse area.
• Investigate evidence for the connection between observed weathering features and the region's cool dry climate or past glaciation.

Strengths

• Provides detailed stratigraphic analysis covering Upper Triassic, Jurassic, and Tertiary geological periods.
• Includes specific study of granitic rock weathering linked to measurable features like pore size.
• Document is an authoritative thesis sourced from the Government of Yukon and available via UBC's open repository.

Limitations

• Data is presented as a textual thesis in HTML format without structured tabular data (rows/columns).
• Sample data and quantitative measurements for rock properties are unavailable in the provided description.
• The description states evidence on weathering relation to glaciation is inconclusive, limiting definitive conclusions.
