Description ABSTRACT
The 1:2 500 000 scale bedrock geology map of Queensland and northwest New South Wales was compiled at
1:500 000 scale, primarily based on the 1:2 000 000 surface geology map of Queensland Geology (2012) by
removing unconsolidated Cenozoic sediments with interpretation of aeromagnetic data and reference to
Geological Survey of New South Wales' interpretation of the Thomson Orogen region (Hegarty 2010). This work
also referred to the geological province work by Stewart et al (2013).
Stratigraphic unit definition data is linked to the Australian Stratigraphic Names Database through the stratno,
by which this bedrock geology map may also be linked to other geoscientific databases housed in Geoscience
Australia.
Geological units are represented as polygon and line geometries, and are attributed with information regarding
stratigraphic nomenclature and hierarchy, age, lithology, and primary data source. The dataset also contains
geological contacts, structural features such as faults and shears, and miscellaneous supporting lines like the
boundaries of water bodies.
NOTE: Specialised Geographic Information System (GIS) software is required to view this data.

Data Quality LINEAGE
The map was compiled at the scale of 1:500 000, primarily based on the Queensland Geology (2012), by
removing unconsolidated Cenozoic geology with interpretation of aeromagnetic data. This work also referred
to the geological province work by Stewart (2013).
Some Cenozoic sedimentary unit boundaries in the southeast part of the state were based on line work of
Cenozoic basin boundaries supplied by Geological Survey of Queensland in 2014.
Data Quality POSITIONAL ACCURACY
Positional accuracy of this data is about 500 m.
Data Quality ATTRIBUTE ACCURACY
Attribute data is the best available at the time of publication. All geological units are fully attributed with
geological unit name, hierarchy, age, and lithological composition according to the Australian Stratigraphic
Units Database (http://www.ga.gov.au/products-services/data-applications/reference-databases/stratigraphicunits.html), which is the authoritative lexicon of Australian lithostratigraphic units.
Data Quality LOGICAL CONSISTENCY
This ESRI Geodatabase dataset has been constructed using ESRI's polygon and line topology verification,
ensuring all geological unit (polygon) boundaries are overlain by corresponding geological contacts (lines). The
data structure conforms to the Geoscience Australia standard for a digital geological map dataset, which is in
turn compatible with the GeoSciML data transfer standard published by the IUGS Commission for the
management and Application of Geoscience Information (www.geosciml.org). Systematic checks have been
made of both unit and line information throughout the entire data set.
