Winton outcrop polygons

\n## **Abstract** \nThe dataset was compiled by the Geological and Bioregional Assessment Program from source data referenced within the dataset and/or metadata. Areas of outcrop of Winton formation as defined by 1:1 million geological surface mapping. Contacts between Winton Formation and alluvium associated with minor drainage features were removed from the polygons, as in these areas the recent alluvium would be underlain by the Winton Formation. These polygons were then used as a template to modify the Cenozoic geological surfaces.\n\n\n## **Attribution** \nGeological and Bioregional Assessment Program\n\n\n## **History** \nOutcrops of Winton polygons were extracted from 1:1 million geological surface mapping. These polygons were then smoothed to remove boundaries that represent edge of alluvium in minor drainage lines. These smoothed polgons were used to clip the Cooper GBA model grid surfaces of the Cenozioc and Eyre and Glendower Formations. Clipping polygons are required as Eyre and Glendower formations cannot be present where the Winton Formation outcrops.
