These data are a digital representation of information depicted on the printed map of the Cambridge Gulf 1:250 000 Geological
Series produced by AGSO and the Geological Survey of Western Australia (GSWA) in 1971. Data present include geological polygons
(litho-stratigraphic units), linear structural features (faults, dykes, folds, trends, lineaments etc), and point features
(mines, structural points etc). Polygons have a range of attributes extracted from each individual map including unit name,
age and lithological description, while lines and points are feature coded according to the AGSO publication 'Symbols Used
On Geological Maps' (BMR 1989). A standard look-up table of AGSO geological codes and associated descriptions is available
(see ADDITIONAL METADATA). The data has gradually evolved from elementary CAD quality data into its present topologically
structured GIS format, and hence has many imperfections and inconsistencies. Data has undergone rigorous validation and testing
that includes over 80 different tests. See ADDITIONAL METADATA for more information on the data standards used.
