Duvernay Interval Isopach and Lithofacies GIS Data

GIS line features represent the thickness and rock composition of the Duvernay Interval within the Western Canada Sedimentary Basin. The data was created by the Alberta Geological Survey in the mid-1990s and later edited in 2005-2006. It is part of a geological atlas published by the Government of Alberta.

Use Cases

• Map subsurface rock thickness (isopach) using line feature geometry and attributes.
• Analyze spatial distribution of lithofacies (rock types) from attributed line features.
• Integrate line features with other geological layers to model the Devonian Woodbend-Winterburn strata.
• Study basin architecture by correlating isopach and lithofacies data across the sedimentary basin.

Strengths

• Data is part of an authoritative geological atlas for the Western Canada Sedimentary Basin.
• Original digital files were created by a government geological survey (Alberta Geological Survey).
• Data was edited and consolidated into single files by feature type in 2005-2006.

Limitations

• The core data originates from the mid-1990s, which may limit modern analytical applications.
• Specific row counts, column details, and sample data are unavailable for assessment.
• The dataset's scope is limited to a single figure (Figure 17) from a larger atlas chapter.
