The Geology of Australia dataset documents the distribution and age of major stratigraphic, intrusive and medium to high-grade metamorphic rock units of onshore Australia. It is an ongoing compilation, subject to periodic revision as additional data becomes available. The dataset was compiled to use at scales between 1:2,500,000 and 1:5,000,000 inclusive. The units distinguished/mapped mainly represent stratigraphic supergroups, regional intrusive associations and regional metamorphic complexes. Groupings of Precambrian units in the time-space diagram are generally separated by major time breaks; Phanerozoic units are grouped according to stratigraphic age i.e. System/Period. The time-space diagram has the added benefit that it provides a summary of units currently included on the themes. The method used to distinguish sedimentary and many volcanic units varies for each geological eon as follows: * Cainozoic units are morphological units which emphasise the relationship of the sedimentary fill to the landscape; * Mesozoic units are regionally extensive to continent-wide time-rock units which emphasise the System of Period(s); * Palaeozoic units are stratotectonic units that emphasise either the dominant System or Period(s) or the range of Periods; * Proterozoic units are commonly regional stratotectonic units - separated by major time breaks and split into the Palaeoproterozoic, Mesoproterozoic and Neoproterozoic Eras - which are generally unique to each cratonic region; and * Archaean units are regional lithological units grouped into broad time divisions. Metamorphic units are lithological units which emphasise the metamorphic facies and timing of the last major metamorphic event. Igneous units are regional units which emphasise the dominant lithology and are grouped into broad time divisions. Note: This is a specialist product and most items in the data set do not comply with the current AGSO GIS standards for digital data

Papua New Guinea Geographic map 1:2 500 000

Pixel map image of the Pilbara area. Composite colour image of K (red), U (blue) and Th (green). Each band histogram equalised. 25% of total count added as a gradient to enhance the visibility of small scale structures.

Northern Territory Stratigraphy map 1:2.5m

This series of maps covers the whole of Papua New Guinea at a scale of 1:250 000 (1cm on a map represents 2.5km on the ground) and comprises 513 maps. This is the largest scale at which published topographic maps cover the entire continent. Each standard map covers an area of 1.5 degrees longitude by 1 degree latitude or about 150km from east to west and 110km from north to south. There are more than 50 special maps in the series and these maps cover a non-standard area some also include imagery and additional narrative information. Typically, where a map produced on standard sheet lines is largely ocean it is combined with its landward neighbour. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours (interval 50m), localities and some administrative boundaries. Some maps are supplemented by relief shading. Coverage: Upon completion of revision the series will cover the whole of Australia with 513 maps. Currency: From 1995 to 2007. Coordinates: Geographical and either AMG or MGA (post-1993) Datum: AGD66, (GDA94 compliant at this stage). Projection: Lambert Conformal Conic. Medium: Paper, flat and folded copies.

The Australian Geological Survey Organisation (AGSO; formerly the Bureau of Mineral Resources, Geology and Geophysics, or BMR) has had a long scientific interest in the NorthWest Shelf, dating back to the earliest systematic surveys of the region, carried out by BMR in1967. The Continental Margins Survey of 1970-73 was the first systematic survey of the continental margin extending to abyssal depths, and in many areas (eg Scott Plateau, northern Exmouth Plateau) it remains the only regional data set available. Since obtaining and fitting out the research vessel Rig Seismic in late 1984/early 1985, BMR/AGSO has carried out two rounds of research on the North West Shelf. The first round (1986) concentrated on heat flow studies on the Exmouth Plateau (Choi, Stagg, & others, 1987) and on multichannel seismic surveying of the margins of the Exmouth Plateau as a precursor to ODP drilling (references). The second round commenced in 1990 and is scheduled to run until late 1993 or early 1994.

Geoscience Australia`s wall map of Australia is ideal for displays and feature walls in offices, classrooms and conference rooms. The four component sheets - North-East, North-West, South-East and South-West are available individually, flat or folded, with each map 103cm x 88cm. The fully assembled size is 2m x 1.7m. At this scale 1cm on the map represents 25km on the ground. This map can be purchased from Geoscience Australia`s Sales Centre or your nearest topographic map retailer. Digital data at this scale, suitable for use in a GIS, is also available for free download.
