Australian National Lexicon of Geologic Units

The national standard lexicon of geologic units, including: age, lithology, geologic relationships for all Australian geological units, and a record of their use in literature. Links to Geological Provinces and Geological Maps.

The collection is maintained by Geoscience Australia on behalf of the Australian Stratigraphy Commission, a standing committee of the Geological Society of Australia.

Value: The lexicon standardises terminology for geologic units, thereby enabling integration of different geologic studies and datasets.

Scope: Covers all Australian Territories, including Australia's Antarctic Territories. The database contains over 17,500 current stratigraphic names and over 36,000 variations, most of which are superseded, obsolete, or misspelt versions of the current names.

The publicly accessible portion of this collection is made available through the Australian Stratigraphic Units Database (ASUD), the national authority on stratigraphic names in Australia and can be accessed here:
