Polygons have a range of attributes including unit name, age, lithological description and an abbreviated symbol for use in labelling the polygons. These have been extracted from the Rock Units Table held in the Department's geologicl properties database. The lines in this dataset are a digital representation of the position of the boundaries of geological units and other linear features such as faults, bedding trends, dykes, fold axial traces, jointing patterns and other unassigned lineaments. The lines are attributed with a description of the type of line represented.
