Werrie Basin component of the Hunter subregion extent

## **Abstract** 

The dataset is derived from the Australian Coal Basins dataset supplied by Geoscience Australia. You can find a link to the parent datasets in the Lineage Field in this metadata statement. The History Field in this metadata statement describes how this dataset was derived.  

This is the eastern discontiguous  part of what the GA Coal Basins dataset has included as "Gunnedah (coal) Basin". However other sources refer to the coal deposit east of the Hunter-Mooki thrust fault as the "Werrie Basin". This area has been extracted from the GA Coal Basins dataset and re-attributed from "Gunnedah Basin" to "Werrie Basin". It is intended for use in report map images only.



Source dataset abstract follows:



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.

## **Dataset History** 

The section of the Gunnedah Basin in the Australian Coal Basins dataset (see lineage) lying east of the Hunter-Mooki fault was extracted and the attibution in the 'Name' field changed from "Gunnedah Basin" to  "Werrie Basin"
