Geological Units as Polygons at 1:50,000 Scale

Geological units represented as two dimensional polygons (1:50,000) contains primary geological data for outcropping and sub-cropping rock units and their boundaries. The dataset, published by the Department of Energy, Environment and Climate Action, includes stratigraphic units down to the member level and features like faults where they form unit boundaries. It was last updated on 2026-04-09.

Use Cases

• Regional geological mapping based on polygon representations of rock units.
• Analyzing stratigraphic relationships based on member-level unit classification.
• Identifying geological boundaries based on contact and fault line data.
• Supporting mineral exploration and land-use planning based on mapped geological features.

Strengths

• Polygon edges are constructed from corresponding geological contacts and faults layer.
• Includes stratigraphic units down to the formal member level.
• Published under a permissive CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total dataset size are unknown, which may limit suitability assessment.
