The current Geological Map of the NT was revised in 2006 and replaces the 2004 version. The revised map incorporates significant changes in the Arunta and Tanami Regions and eastern Pine Creek Orogen. A feature of the map is the division of the Proterozoic into ten regionally identifiable and generally unconformity-bounded packages (P1-P10). These divisions have been made to best reflect important packages in Northern Territory geology, and do not correspond to the chrono-stratigraphic subdivisions recommended by the Subcommission on Precambrian Stratigraphy, except for P10 which relates to the Neoproterozoic. A convenient chronometric scale has been used to define the boundaries of these packages. The Phanerozoic is subdivided according to the conventional geological time scale. The map is based on compilation of data from existing 1:250 000 geological maps, along with interpretation of regional geophysical data.

Data Quality

Lineage: This dataset is updated from the 2006 version. Individual regions are updated by project geologists mapping at scales between 1:100 000 and 1:500 000. Line work is generalised to match geology at 1:2 500 000.
Map compiled using overlays form the complete coverage of first edition, and partial coverage of second edition 1:250,000 scale geological maps, published by the Northern Territory Geological Survey and Geoscience Australia; augmented

Positional Accuracy: Accuracy relevant to the scale of production 1:2 500 000, approximately 1000m.

Attribute Accuracy: Attributed by geologists with over 15 years experience in the NT.

Logical Consistency: Logical consistency was validated by tests to check that table and file names are set out as in the Data Dictionary. Graphical tests checking details such as intersections, polygon closure, minimum sizes of polygons and length of linear features were also carried out

Completeness: Complete
