This is a group layer consisting of the following datasets:

• Geological Structure - Structure data is available at 1:25 000 and 1:250 000 scales. The data has been captured from old map compilation data or from locations recorded in the field using GPS. Each structure reading is one record in the dataset however, there may be multiple structural readings taken at one location. The 1:25 000 structure dataset has a 'secondary' structure symbol to allow fold hinge line structure readings to be paired with and accompanying axial surface reading. The 'secondary' fields will only be populated for fold, for all other structure symbols these fields will be NULL.

• 1:25 000 Geology - Includes separate layers for Outcrops, Faults, Contacts, other Linear features, and Geology Units. Geology and structure data derived from existing reports, 1:25,000 1:50,000 and 1:63,360 scale printed maps, new field mapping and interpretation of aerial photography and airborne geophysical data.

• 1:250 000 Geology - Includes separate layers for Faults, Contacts, other Linear features, and Geology Units. Geology and structure data derived from 1:50,000 and 1:63,360 Digital Geological Atlas printed map series and 1:25,000 digital geology data where available. Geological units and boundaries have been generalised and compiled for 1:250,000 scale.

• 1:500 000 Geology - Includes separate layers for Faults, Contacts, and Geology Units. Derived from higher resolution mapping and generalised for 1:500 000 scale display.
