Geology of Whitehorse and Carcross Map Areas in Yukon, Canada

Plutonic rocks cover approximately 40% of the project area and comprise over 30 individual bodies. The dataset describes the geology between Whitehorse and the Yukon-BC border, including three allochthonous terranes, Cretaceous and Tertiary igneous rocks, and sedimentary rocks from the Upper Triassic to Late Cretaceous. It was published by the Government of Yukon and last updated in April 2026.

Use Cases

• Map terrane boundaries and structural geology based on described allochthonous terranes and fold trends.
• Model plutonic emplacement and composition based on the six distinct chrono-lithological suites.
• Analyze sedimentary basin evolution based on the stratigraphy of the Whitehorse Trough and successor basins.
• Correlate volcanic activity and tectonic regimes based on described Cretaceous and Paleocene/Eocene volcanic groups and dyke swarms.

Strengths

• Plutonic rocks cover approximately 40% of the project area, providing significant coverage of igneous features.
• Describes over 30 individual plutonic bodies with a wide range of compositions.
• Includes detailed stratigraphic descriptions for multiple geological groups and formations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
