Cretaceous Second White Specks Petroleum System Polygons

Western Canada Sedimentary Basin geological data details the Cretaceous Second White Specks petroleum system as polygon features. The dataset was created by the Alberta Geological Survey from mid-1990s files and later edited in 2005-06. It originates from Chapter 31 of the Geological Atlas of the Western Canada Sedimentary Basin.

Use Cases

• Model petroleum system boundaries and extents using polygon geometry features.
• Analyze spatial relationships between source rock kitchens and migration pathways defined in the shapefile attributes.
• Integrate polygon data with other subsurface layers for basin-scale geological mapping.

Strengths

• Data is part of a formal Geological Atlas reference volume for the Western Canada Sedimentary Basin.
• Polygon features were consolidated and attributed into single files by feature type for consistency.

Limitations

• Underlying data originates from the mid-1990s, potentially lacking modern geological interpretations.
• Specific row counts, column details, and sample data are unavailable for assessment.
• The dataset's consolidation in 2005-06 suggests it is not actively updated with new discoveries.
