Abstract
The Australian Stratigraphic Units Database (ASUD) is the lexicon of Australian stratigraphy, maintained by Geoscience Australia on behalf of the Australian Stratigraphy Commission (ASC). Initiated in 1949 as the Australian Central Register of Stratigraphic Names, the ASUD became a digital database in 1979, and is now accessible through the Geoscience Australia website (http://www.ga.gov.au/products-services/data-applications/reference-databases/stratigraphic-units.html) with search capabilities on attributes such as name, rank, age, state, and geological province. The ASC includes representatives from all Australian states and territories (generally government geologists) who work together to maintain the consistency, accuracy and currency of information in the database. This includes resolving stratigraphic differences across political borders and between researchers to maintain it as a truly authoritative national resource. The database is continually updated with information collated from all publications that describe Australian stratigraphic units, including journal articles and Geological Survey maps and publications. Where possible, data quality within the ASUD is enforced by codelists (eg, rank, lithology, age, age determination method, relationship types). Information includes unit definitions, currency, rank, location, age, lithologies, composition, and environment of formation. It also includes relationships with other units (eg, overlying, intruding, correlated units), hierarchy (constituent and parent units), previous names, related geological provinces (eg, basin, craton), and links to all publications that reference a stratigraphic unit. The ASUD is a central cog in Australia's national digital geological datasets. It is the repository of all unit descriptions in the national digital geological map datasets, and is linked to the national mineral deposits, geological provinces, and geological samples databases.
