Yukon Rock Physical Properties from Geological Surveys

Rock property data compiled from Yukon Geological Survey field projects and archival collections, including the Geological Survey of Canada's database. A foundational mapping project from 1970-1972 contributed 1,642 records. The dataset covers a range of lithology classes and terranes and continues to grow with new sample measurements.

Use Cases

• Analyze magnetic susceptibility measurements across different lithology classes and terranes to identify geophysical signatures.
• Model specific gravity distributions to characterize rock density variations within Yukon's geological units.
• Map the modernization of historical map unit names against current geological understanding for regional studies.
• Integrate data from the HS Bostock Core Library's >10,000 rock samples to expand representation in specific regions.

Strengths

• Contains 1,642 records from a foundational digitized mapping project.
• Draws from a core library housing over 10,000 Yukon rock samples for potential expansion.
• Incorporates systematic measurements like magnetic susceptibility and specific gravity from ongoing workflows.

Limitations

• Data distribution is not uniform, leading to potential gaps in representation for some lithology classes or terranes.
• Rock samples are not uniform in size or weight, which may affect the comparability of physical property measurements.
• Samples are not collected specifically for this dataset, which may introduce bias towards certain project types or regions.
