This service contains the NATMAP 1:250,000 scale maps, from the NATMAP Digital Maps 2008 DVD. The large scale single mosaic map covers the entire continent, and is based on the Geocentric Datum of Australia 1994 (GDA94) geographic projection. The maps have been revised using a variety of data sources, including SPOT and Landsat satellite imagery, other government agency information and data supplied by private companies and individuals. The original DVD was produced by Geoscience Australia's National Mapping Division and its predecessor, the Australian Surveying and Land Information Group (AUSLIG).

Abstract This dataset contains the files generated for the Beetaloo Sub-basin Chance of Success Mapping undertaken as part of the Geological and Bioregional Assessments Program. Play fairway mapping was used to map the distribution of petroleum plays likely to be developed in a 5 to 10 year time frame. This process aims to address the geological factors likely to assist in identifying whether a viable petroleum play is likely to be present, and makes no attempt to factor economics, politics, or social factors into the assessment. ## Attribution Geological and Bioregional Assessment Program ## History This data set contains image files pertaining to chance of success prospectivity assessment for the Beetaloo Sub-basin. This was undertaken in Stage 2 of the Geological and Bioregional Assessment Program and described in Hall LS, Wang L, Bailey A, Orr M, Owens R, Lech M, Skeers N and Woods M (2020) Petroleum prospectivity for the Beetaloo Sub-basin. Technical appendix for the Geological and Bioregional Assessment Program: Stage 2. Department of the Environment and Energy, Bureau of Meteorology, CSIRO and Geoscience Australia, Australia. All files use the Map Grid of Australia (MGA) projection (zone 53) and the Geocentric Datum of Australia 1994 (GDA94). Datasets were generated using Petrosys software in Geoscience Australia.

Abstract

The dataset was derived by the Bioregional Assessment Programme from natural resource management regions and topographic data provided 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.

Version 2 of the approved boundaries of the bioregions and subregions for defining the reporting regions for Bioregional Assessments of impacts of coal seam gas and coal mining development on water resources.

This release contains two spatial dataset vector layers:

ba_bioregion_alb_gda94_v02p1 is a topologically and geometrically correct spatial layer of the approved bioregions for the Bioregional Assessment Program. This layers' extent outlines the bioregions for the Assessment teams only.

ba_bioregion_and_subregion_alb_gda94_v02p1 is a topologically and geometrically correct spatial layer of the approved bioregions and subregions for the Bioregional Assessment Program. This layers' extent outlines the bioregions and subregions for the Assessment teams only.

The two layers are coincident with the three input layers and inherited the coordinate system of the parent layers (Geographic Coordinate System, Geocentric Datum of Australia 1994):

1. Coal Basins sourced from Geoscience Australia Geological Provinces.

2. Natural Resource Management (NRM) regions based upon catchments or bioregions which have been identified by the Australian Government, in association with state and territory governments.

3. The continental scale Coastline from Geoscience Australia (Topo 250K).

Purpose

The dataset is designed to delineate the spatial area of the various bioregions being assessed as part of the Bioregional Assessments Program.

Dataset History

The layers are coincident with the three input layers & inherited the coordinate system of the parent layers (Geographic Coordinate System, Geocentric Datum of Australia 1994):

1. Coal Basins sourced from Geoscience Australia Geological Provinces (GUID =13ad6933-ee80-4c51-a97b-bac1e8bef16d).

2. Natural Resource Management (NRM) regions (GUID = 1d54e38f-4051-4f0c-a350-c7dbd8eba65b) based upon catchments or bioregions which have been identified by the Australian Government, in association with state and territory governments.

3. The continental scale Coastline from Geoscience Australia (Topo 250K, GUID = 96ebf889-f726-4967-9964-714fb57d679b).

It was created using a number of ArcGIS (ESRI) geoprocesses; clip coal basins to onshore extent, intersect coal basins with NRM boundaries; merge regions to single layer.

This method (verified by a check & repair of geometry/topology) avoided the errors introduced in earlier versions.

Further, changes to the extents for the Northern Inland Catchments (NIC) bioregion, the Clarence-Moreton (CLM) bioregion, the Northern Sydney Basin (NSB) bioregion, and the Southern Sydney Basin (SSB) bioregion (consistent with the Decision Paper presented to & accepted by the BA Board 23rd August 2013) have been included in this updated version.

Clarence-Moreton (CLM) had the area north of the Lockyer Valley (refer to AWRC catchment mapping - GUID = d4561e86-2d13-4dcb-bf9e-aae75ba4850c) was excised & added to the Maranoa-Condamine-Balonne (MBC) subregion of the Northern Inland Catchments (NIC) region.

Northern Sydney Basin (NSB) bioregion, and the Southern Sydney Basin (SSB) bioregion were delineated using the NRM layer (2. above).

The boundary layer was then projected to Australian Albers 1994; EPSG 4283, the agreed projection for maps in technical products, as recorded in the 'Product standards for the bioregional assessments v17'.

Whilst these layers have origins similar to the layer used in the Office of Water Science Bioregional Assessment Priority Areas VERSION 1 map, they differ in that the Lake Eyre Basin (LEB) Assessment Area now consists of the four subregions & does not include a record for the Lake Eyre Basin extent. This avoids the confusion that the reporting areal extent is Lake Eyre Basin, rather it is a convenient named entity that has been inherited from the early identification of Coal Development Pathways based upon the Geoscience Australia Coal Basins spatial polygon dataset.

Two full-colour map sheets (at 1:5 million and 1:10 million scales) that show the continental extent and age relationships of Proterozoic mafic and ultramafic rocks and associated mineral deposits …Show full descriptionTwo full-colour map sheets (at 1:5 million and 1:10 million scales) that show the continental extent and age relationships of Proterozoic mafic and ultramafic rocks and associated mineral deposits throughout the continent. These rocks have been assigned to 30 Magmatic Events (ME) ranging in age from the Early Palaeoproterozoic ~2455 Ma (ME 1) to the Early Cambrian ~520 Ma (ME 30). The presence and correlation of these Magmatic Events into five Major Crustal Elements and 28 provinces are represented in a Time-Space-Event Chart on Sheet 2. Enlarged inset maps on Sheet 1 provide in more detail the polygon and line data of certain regions, and other inset maps on Sheet 2 show the distribution of Proterozoic and Archaean rocks, mineral deposits and occurrences, and five Large Igneous Provinces (LIPs). This national map supersedes two similar 'Proterozoic Mafic-Ultramafic Magmatic Events' maps relating to Western Australia (2006; GeoCat 64813) and the Northern Territory-South Australia (2007; GeoCat 65257). A user guide to the map series is described in Geocat 66624. A georeferenced image of the map Australian Proterozoic Mafic-Ultramafic Magmatic Events (Sheet 1) is also provided. The image shows spatial distribution of Proterozoic (2500 Ma to 545 Ma) mafic-ultramafic magmatic events in Australia. The map illustrates for the first time, the continental extent and age relationships of Proterozoic mafic and ultramafic rocks and their associated mineral deposits. The image has been georeferenced using ESRI ArcGIS 9.3 software.
