Geological units represented as two dimensional polygons (1:250,000)

This dataset contains primary geological data, namely outcropping/sub-cropping geological rock units and boundary types separating rock units. Other geological features (e.g. fault or dyke) are included where the feature forms a boundary to rock units. The polygon edges are constructed from the corresponding geological contacts and faults layer. This layer contains stratigraphic units down to the formation level for formal geological units.
