The Australian Geological Provinces Database contains descriptions and polygon outlines of geological provinces of the Australian continent and surrounding marine jurisdictional area. The provinces are mapped at a nominal 1:1 million scale. The database can be interactively queried, and the results retrieved as reports and maps. Attributes include igneous, sedimentary and structural characteristics, age limits, parent and constituent units, relations to surrounding provinces, and mineral and petroleum resources.

Scanned 250k geological maps of Australia in geotiff format. Data is cropped to map graticule, rectified to geographic coordinate system, GDA94, GRS80 ellipsoid. Data is uncompressed, not tiled, 8bit colour, 250dpi and 25m pixel size. The map editions are current only to 2002.

A seamless Regolith Map of Australia drawn from field-defined regolith-landform data at approx 1:250k scale for QLD and NT, and additionally from SA regolith data derived from the South Australian Regolith Map (1:2 Million) published in 2012, and generalised by Geoscience Australia to 1:5 000 000 for matching with existing data.

Mapped and projected extents of geology and geologic features in Australia, including: surface geology, regolith geology, solid geology, chronostratigraphic surfaces, and province boundaries. The database includes igneous, sedimentary and structural characteristics, age limits, parent and constituent units, relations to surrounding provinces, and mineral and petroleum resources. based on field observations interpretations of geophysics and borehole data. <b>Value:</b> Data used for understanding surface and near surface geology. The data can be used for a variety of purposes, including resource exploration, land use management, and environmental assessment. <b>Scope:</b> Australia and Australian Antarctic Territory

The 1:2.5M scale geology of Australia data documents the distribution and age of major stratigraphic, intrusive and medium to high-grade metamorphic rock units of onshore Australia. This edition contains the same spatial content as the previous edition, but its geological attribute data is more complete than the 2010 edition. The dataset was compiled to use at scales between 1:2.5 million and 1:5 million inclusive. The units distinguished/mapped mainly represent stratigraphic supergroups, regional intrusive associations and regional metamorphic complexes. Groupings of Precambrian units in the time-space diagram are generally separated by major time breaks; Phanerozoic units are grouped according to stratigraphic age i.e. System/Period. The time-space diagram has the added benefit that it provides a summary of units currently included on the themes. The method used to distinguish sedimentary and many volcanic units varies for each geological eon as follows: - Cainozoic units are morphological units which emphasise the relationship of the sedimentary fill to the landscape. - Mesozoic units are regionally extensive to continent-wide time-rock units which emphasise the System of Period(s). - Paleozoic units are stratotectonic units that emphasise either the dominant System or Period(s) or the range of Periods. - Proterozoic units are commonly regional stratotectonic units - separated by major time breaks and split into the Paleoproterozoic, Mesoproterozoic and Neoproterozoic Eras - which are generally unique to each cratonic region. - Archaean units are regional lithological units grouped into broad time divisions. Metamorphic units are lithological units which emphasise the metamorphic facies and timing of the last major metamorphic event.

The Regolith Map of Australia 1:5M scale dataset (2013 edition) is a seamless but partial national coverage of regolith-landform units, compiled for use at, or between 1:5 million, and 1:1 million scale. The data maps high-level regolith-landform units. The units appear as polygon geometries, and with attribute information identifying high-level regolith and landform nomenclatures and their hierarchy. The 2013 dataset is a completely new portrayal of Australia's regolith from that presented much earlier in 1986, in which a whole of continent view of Australia's regolith was based on a simpler desktop-based 1:5 million continental regolith terrain assessment, not directly linked with landforms and published by the Bureau of Mineral Resources Geology and Geophysics. The 2013 edition incorporates new published mapping in South Australia (2012), integrated with earlier field-based regolith-landform mapping data from the Northern Territory (2006) and later Queensland (2008). The attribute structure of the new dataset is also revised to be more compatible with the GeoSciML data standard, published by the IUGS Commission for Geoscience Information. The map data is compiled largely from simplifying and edge-matching of 1:250 000 scale regolith compilation maps. Some source regolith and geologic maps ranging in scale from 1:50 000 to 1:1 million were used together with LANDSAT7, radiometric, magnetics, and gravity imagery, in addition to a 9 second digital elevation model.

The Australian Geological Provinces Database contains descriptions and spatial extents of the fundamental geological elements of the Australian continent and offshore surrounds. Province types include sedimentary basins, tectonic provinces such as cratons and orogens, igneous provinces, and metallogenic provinces. Spatial data has been captured largely at approximately 1:1M scale for intended use between 1:2M and 1:5M scale. This edition (2018.01) of the dataset is NOT a complete representation of all of Australia's geological provinces. Further work is required to complete the national geological province collection. Additionally, not all the provinces supplied herein have undergone a rigorous quality assurance (QA) check to ensure the accuracy and completeness of their descriptions. Where possible, provinces have been attributed with their age, contained lithostratigraphic units, relationships to other provinces, geological history, mineral resource occurrences, and selected published references. The geological definition of some provinces is contentious. While every effort has been made to achieve a consensus interpretation of each province, including significant collaboration with state and territory geological surveys, scientific debate may still occur about the nature and extent of some provinces. The full 2D spatial extent (ie, including the extent of a province under any overlying cover material) of provinces has been captured. Additionally, the extent of outcrop of some provinces has also been captured. Where possible, the full extent outlines of provinces have been attributed with information about the source, accuracy, and observation method of those lines.

The Surface Geology of Australia data package includes: - Surface Geology of Australia, 1:1M scale (2012 edition) [GeoCat #74619 ] - Surface Geology of Australia, 1:2.5M scale (2012 edition) [GeoCat #73140 ], and - the national Geological Regions dataset [GeoCat #32366 ].

This data set is a classification of the Australian continent into 2-dimensional surface regions. A geological region is a relatively large geographical area with a cohesive, albeit in some cases complex, geological assemblage (Bain and Draper 1997, AGSO Bulletin 240); significantly different in overall geology from the adjoining regions, and differs from geological province in that it does not include depth or time dimensions. NOTE: Specialised Geographic Information System (GIS) software is required to view this data.
