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.

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.

<p>The 1:1 million scale Geology of Tasmania dataset is generalised from the 1:500 000 scale 'Geology of Tasmania' map published in 1999 by the Tasmanian Geological Survey, with updated granite nomenclature from the 2005 1:500000 scale 'Tasmanian Granites and Associated Mineralisation' map. <p>The geology of Tasmania consists of a wide range of sedimentary, igneous and metamorphic rocks. The oldest rocks are Proterozoic clastic sedimentary rocks of the Tyennan and Rocky Cape Regions, which form basement cores in the central-west and north-west of Tasmania respectively. Low to medium grade metamorphic rocks are found in the Arthur Metamorphic Complex along the Arthur Lineament on the eastern margin of the Rocky Cape Region. The economically significant middle Cambrian Mt Read Volcanics, comprising calc-alkaline felsic to mafic volcanics, related intrusives and associated volcanosedimentary rocks, occur in an arcuate belt in the western part of Tasmania. The late Cambrian to early Devonian Wurawina Supergroup, including the Eldon, Gordon and Denison Groups, is a sequence of mainly clastic sediments (siltstone, shale, sandstone, conglomerate) and minor limestone. The supergroup overlies the Mt Read Volcanics and crops out in the western and central parts of the state. <p>The early Ordovician to early Devonian Mathinna Group, comprised of predominantly turbiditic metasediments, crops out in the north-east of the state. It is intruded by a suite of middle Devonian to early Carboniferous granitoids which extends across the northern part of Tasmania. <p>The late Carboniferous to Triassic Parmeener Supergroup of the Tasmania Basin crops out over much of the state. It consists of Triassic fluviolacustrine and Permian glaciomarine sequences. Much of Tasmania's rugged landscape is formed of Jurassic dolerite which presently extends over half of the area of Tasmania. Tertiary basalt and related pyroclastic rocks are found across much of the state.
