Australian Coal Basins

Brief description

## **Abstract**

This dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.



The Coal Basin Outlines dataset is a combination of data from various sources displaying the best available (7 March 2013) coal basin extents for all of Australia. These extents were taken predominantly from the Australian Geological Provinces Database(extract from 4 November 2012 - see metadata statement below) with additional data coming from the Australian Sedimentary Basins Database (27 August 2012 update), State (South Australia) basin databases and hydrogeological basin databases.



The Australian Geological Provinces Database contains descriptions and spatial extents of the fundamental geological elements of the Australian continent and immediate surrounds. Captured 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 best use at between 1:2M to 1:5M scale.

Where possible, provinces have been attributed with their age, contained lithostratigraphic units, relationships to other provinces, and geological history. The geological definition of some provinces, in particular certain sedimentary basins and orogens, is contentious. While every effort has been made to achieve a consensus interpretation of each province, scientific debate may still occur about the nature and extent of some provinces.



The total 2D spatial extent of most provinces in the database has been captured (ie, the full extent of a province under any overlying cover). 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.

## **Purpose**

Note that these datasets are pre-release data. While every effort has been made to maintain accuracy and precision during data compilation, the data have not been fully QA checked for public release. This was extracted from the database on 01/11/2012.

## **Dataset History**

The following list shows which database each basin was derived from:

Australian Geological Provinces Database (4 November 2012): Arckaringa, Bowen, Clarence-Moreton, Cooper, Eucla, Galilee, Gippsland, Gloucester, Gunnedah, Marybourough, Mulgildie, Murray, Otway, Pedirka, Perth, Polda, Styx, Surat, Sydney and Tasmania basins



Australian Sedimentary Basins Database (27 August 2012): Canning Basin (Fitroy Trough), Eromanga, Oaklands, Collie, Boyup, Wilga and Leigh Creek basins



State provided data - South Australia: St Vincents Basin



Hydrogeological Basin Data: Laura Basin



Feature Classes:

ProvinceFullExtent - polygons showing the full 2D spatial extent of a province. This includes non-outcropping regions of a province that may be concealed by regolith or other overlying provinces. The ProvinceFullExtent feature class has two related tables, linked through relationship classes:

- ProvinceRelations - this table lists relationships between provinces (eg, the Surat Basin overlies the Bowen Basin)

- ProvinceStratigraphy - this table list the stratigraphic units contained within a province. Full details of each stratigraphic unit are available at http://dbforms.ga.gov.au/www/geodx.strat_units.int

ProvinceOutcrop - polygons showing the outcropping extent of a province. Note that not all provinces have this data available.

ProvinceFullExtentBdy - lines overlying the margins of province full extent polygons showing the nature of contacts between provinces, data source, and spatial accuracy. Note that not all provinces have this data available.
