  • The Surface Hydrology Points (Regional) dataset provides a set of related features classes to be used as the basis of the production of consistent hydrological information. This dataset contains a geometric representation of major hydrographic point elements - both natural and artificial. This dataset is the best available data supplied by Jurisdictions and aggregated by Geoscience Australia it is intended for defining hydrological features.

  • Geoscience Australia`s involvement in Papua New Guinea mapping includes managing the production of maps for select urban areas as part of a MOU between Department of Defence and PNG. In addition, Geoscience Australia distributes some (now aging) 1:100,000 scale maps produced by the Department of Defence for much of Papua New Guinea.

  • A map extending outcropping geological units below shallow cover, based in large part on identification of magnetic features.

  • These data are a digital representation of information depicted on printed maps from the Australia 1:250 000 Geological Series produced by AGSO and the Northern Territory Geological Survey (NTGS) between 1963 and 1998. The data are in a tiled format and are not seamless, although basic edgematching has been done where possible. Tiles are arranged according to the standard Australian 1:250 000 sheet breakup. The complete dataset is comprised of the 90 tiles covering the Northern Territory.

  • The surface geology of Eastern Australia was compiled from State-wide compilations (1:500 000 Tasmania, 1999; 1:1M Victoria, 1999), a geodatabase of diverse vintage 1:250 000 scale maps (New South Wales), regional basin compilations (eg. Northern Eromanga Basin, 1977; Murray Basin, 1991) and recent 1:100 000 scale mapping (eg. south-east Queensland, north-east New South Wales). Modifications to the source data included edgematching, generalisation of detailed geology to 1:1,000,000 scale, and rationalisation of surficial Cainozoic deposits into standardised regional units. The dataset includes over 3500 named, unnamed or informal geological units. The surface geology of eastern Australia comprises rocks ranging in age from the Palaeoproterozoic to Recent. The oldest rocks comprise high- to low-grade metamorphic rocks which crop out in the Mt Isa, Georgetown regions of northwest and north Queensland, and the Broken Hill region of western New South Wales. Rocks of Mesoproterozoic to Neoproterozoic age crop out in the Coen Inlier and around Charters Towers in North Queensland, the Anakie inlier in central Queensland, to the north of Broken Hill in New South Wales, and in western Tasmania. Extensive, Cambrian to Ordovician aged, carbonate-dominated, marine sediments occur in the Georgina Basin in northwest Queensland. These rocks were deformed during the mid-Ordovician Thompson Orogeny. Clastic sediments of Cambrian age accumulated in western Victoria along with ocean floor basalts which are now exposed along north-trending fault zones in central and eastern Victoria. In Tasmania, calc-alkaline felsic to mafic volcanics and associated volcanosedimentary rocks of the Mt Read Volcanics and Dundas Trough were deposited in the middle Cambrian. These rocks occur in an arcuate belt in the west and northwest of the state, and were deformed during the latest Cambrian-Ordovician Delamerian Orogeny. The geology of eastern Tasmania, Victoria, and south-eastern New South Wales is dominated by the Palaeozoic rocks of the Lachlan Orogen. The orogen comprises marine sediments and volcanics of Ordovician to Devonian age which are overlain by widespread Late Devonian fluvial sediments. The orogen also contains voluminous granitoids of Silurian to Carboniferous age. A strong north-south structural grain is developed through the Orogen from multiple periods of deformation which culminated in the early Carboniferous Kanimblan Orogeny. Palaeozoic rocks of similar character to the Lachlan Fold Belt also crop out in the Hodgkinson and Broken River Basins of north Queensland. South-east Queensland and north-east New South Wales are underlain by the Palaeozoic to Mesozoic sediments and volcanics of the New England Orogen. Extensive Permian to Triassic granitoids intrude the New England Orogen. Both the Lachlan and New England Orogens are overlain by extensive Permian to Recent aged sedimentary basins which cover much of central-eastern Australia, including the Great Australian Basin and Murray Basin. Cainozoic basalt, associated with continental hot-spot volcanoes, is common throughout the eastern Australian highlands.

  • This map was compiled at 1:250,000. Each polygon has regolith and landform types as minimum attributes. The dataset contains the arc/info files, a copy of the CYPLUS report, and a copy of the GA regolith mapping handbook. Regolith in the CYPLUS area in North Queensland consists of both in situ weathered bedrock and transported materials. In situ weathered bedrock includes: 1. Deep weathering profiles with bauxite, mottled and pallid zones, found on remnant land surfaces 2. Residual sand over moderately weathered saprolite in areas of relatively low geomorphic activity 3. Thin soils lying directly on slightly weathered or unweathered bedrock on steeper slopes and unstable areas Transported regolith includes: 1. Large areas of alluvium in fans in the east, and a small area of slightly dissected fan alluvium in the south west 2. Narrow strips of alluvium, with occasional terraces, along the major rivers 3. Coastal sediments (beach ridges and estuarine sediments) 4. Small areas of colluvium in footslopes below steeper hill slopes Iron cementing forms immature ferricrete in a few locations. Siliceous cementing is more widespread, both in present valley floors, and as silcrete in alluvium that now caps small remnant land surfaces.

  • This data package is an archive of geospatially located and other digital geological and geophysical data covering the Tennant Inlier in the Northern Territory, a portion of the North Australia Project undertaken to understand elements within the North Australia Craton and its boundaries. It includes digital geospatial data and/or images for a number of regional scale, 1:250 000 scale and 1:100 000 scale geological map sheets, mineral locations, geophysical images, company drill hole and rock chip locations, company and Geoscience Australia geochemistry, and other regional themes. It also includes geophysical gravity data acquired by the project in the Tennant Inlier, including an ERMapper data set.
