Upper Cambrian Lithology Siltstone Features In Western Canada Basin

Geospatial line features represent siltstone lithology units from the Upper Cambrian to Lower Ordovician period in the Western Canada Sedimentary Basin. The data was created by the Alberta Geological Survey in the mid-1990s and later edited in 2005-2006 for corrections and consolidation. It is part of a larger geological atlas documenting subsurface geology.

Use Cases

• Map the spatial distribution of siltstone units using the geospatial line features.
• Analyze the relationship between siltstone lithology and other geological formations within the basin.
• Integrate these historical line features with modern geological maps for comparative stratigraphic studies.
• Use the attributed shapefile data to model subsurface geology for resource assessment.

Strengths

• Data was edited and consolidated in 2005-2006 to correct and attribute features.
• Represents a specific, documented figure (Figure 21b) from a published geological atlas.

Limitations

• Original digital files were created in the mid-1990s, so the underlying data collection methods may be outdated.
• Specific row counts, column details, and sample data are unavailable for assessment.
• The data focuses solely on siltstone lithology for a specific geological time window.
