This digital dataset is a compilation of the best digital geological map data available in September 1996, drawn mostly from Department of Mines and Energy Queensland (DME) and AGSO published 1:100k, 1:250k, 1:1mil and 1:2.5mil scale geological maps, supplemented by Cainozoic geology from AGSO/(Cape York Peninsula Land Use Strategy) CYPLUS regolith landform and coastal zone maps. The 45 different map units reflect logical age/lithology groupings selected to provide a compromise between readability in hardcopy at 1:1mil scale and a useful amount of information. Internal boundaries of units grouped together were eliminated but the identity of mapped units within each polygon has been added to info tables. The digital dataset was constructed as a basis for hardcopy map products - a 1:1mil scale geological map and a 1:3mil scale geological atlas to accompany AGSO Bulletin 240 - not as a digital product per se. Subsequently, in 2001, the dataset was upgraded to serve as part of a new 1:1mil scale outcrop geology map of Australia. This work comprised QA/QC of linework and attributes, and the addition of polygon constituent information.

The Geophysical Airborne Survey Index presents a summary of the essential specifications of over 800 airborne surveys held in the National Airborne Geophysics Database.

This project is based on the recognition that combinations of specific granite types and distinctive host rocks tend to be associated with certain types of Au, Cu, Zn, Pb, Sn and W mineralisation. Rarely is Proterozoic mineralisation hosted by granites themselves, for the most part being hosted in the country rock, often three or more kilometres from the nearest known granite. There is an apparent host rock control on the deposition of metals: this can be both compositional and also controlled by the competency of the host lithologies. This compositional host rock control has been documented by Stuart-Smith et al. (1993 - Geology and mineral deposits of the Cullen Mineral field, AGSO Bull. 229) for the Pine Creek Inlier and noted in the eastern Mount Isa Inlier by Wyborn and Heinrich (1993 - The relationship between late-tectonic felsic intrusives and Cu-Au mineralisation in the Eastern Fold Belt, Mount Isa Inlier, Trans Royal Soc Edinburgh, Earth Sci, 83, 201-209). This project collated data on the Proterozoic granites and their comagmatic volcanics, the mineralogical composition of the rocks that they intrude and briefly assessed the style and type of mineralisation present within 5 kms of an outcrop of granite. All data collated in the reports is built into the accompanying GIS, and essentially each item listed in the report is converted into a searchable item within the GIS. This project has aimed to provide the data and interpretations to show the following: 1) Which Proterozoic granites have metallogenic potential, 2) What commodities they are likely to be associated with, and 3) Where the better host rocks are located that are likely to host potential mineralisation. <p>Related material<a href="https://www.ga.gov.au/products/servlet/controller?event=GEOCAT_DETAILS&amp;catno=33388">The metallogenic potential of Australian Proterozoic granites.

This second edition, coming after the first one published in 1990, has been entirely revised in order to show a clear distinction between sedimentary, volcanic extrusive, and endogenous dated formations. The geology of the oceans has been also updated according to the most recent magnetic and satellite-gravimetric data. Positions of the main volcanoes and meteoritic craters were added to the map. The new cartographic conception of the map allows a rapid visual reconstruction of the main plates and sub-plates of the global tectonics. This geological wall map is the only one existing today that presents the world geological setting at a glance. There is a clearly distinguishable contrast between the continents - whose rocks may attain an age up to nearly 4 billion years&endash; and the oceanic crust - whose age does not exceed 200 million years.

The two versions of the printed Topographic Map Index are: - the 1:100,000 / 1:250,000 Topographic Map Index - the 1:50,000 Topographic Map Index Topographic map indexes are also available as digital data. Maps are listed by name on the back of the index. The 1:50,000 Index also lists availability of Orthophoto Map (OPM) and Topographic Line Map (TLM) for available 1:50,000 maps. Both indexes are available in printed form from your nearest topographic map retailer or from the Geoscience Australia Sales Centre. You can also download PDFs of each index. Note: To print these PDFs at 100% requires an A0 printer. They are best for viewing on-screen. For new maps which may have been released after these indexes were published, please refer to the new releases page or use the Product Search tool.

This grid represents gravity anomalies of the Australian region. The grid combines accurate onshore gravity measurements, a sub-sample of the levelled offshore marine gravity traverses with satellite data used in areas where there is no marine data. The cell values represent simple Bouguer anomalies at a density of 2.67 tm-3 onshore and free-air anomalies offshore. The grid cell size is 0.5 minutes of arc, which is equivalent to about 800 metres. The smallest wavelength contained in the grid is 1600 m.

A geotechnical landscape map of Australia has been drawn depicting regions of constant [geological and physical] (NOT geophysical {Ed}) properties for road construction. The map, drawn at a scale of 1:2 500 000 for clarity, has a true accuracy of a 1:5 000 000 scale map, and is based on the four variables - landform, underlying lithology, soil type and [surficial] lithology - which are the principal [geological and physical] determinants for road construction. The origins and interpretation of the source maps together with a description of the legend of the geotechnical landscape map are described in this Report. Precis {Ed}: A map delineating regions with differing geotechical properties with particular application to road construction.
