Abstract
Since the early 2000s Geoscience Australia has been compiling new seamless national continental scale geological maps. The first edition of a seamless 1:1 000 000 scale surface geology map of Australia was released in 2008 [1] and the latest edition released in 2012 [2]. This work draws extensively from available geological mapping in Australia, primarily at the scales of 1:250 000 and 1:100 000 with the addition of some special regional scale maps. The digital GIS dataset is linked to other national geoscience databases at Geoscience Australia, including the Australian Stratigraphic Units Database. In September 2013, Geoscience Australia released the first national Geological Provinces dataset [3]. Geoscience Australia's Geological Provinces Database captures detailed information such as age, stratigraphy, lithology, mineral resources, and relations to other provinces. It also captures outlines of the full (ie, concealed) extent and outcropping extent of a province. As part of Geoscience Australia's contribution to Searching the Deep Earth [4], current continental scale digital geological mapping in Geoscience Australia includes production of a new national bedrock geological map at 1:2 500 000 scale with stratigraphic units information that can be linked with other national geoscience databases, basement geology, and a national regolith landforms coverage. Looking ahead, a goal is to produce seamless, continental scale basement or 'solid' geology maps for a variety of depth/time slices. A recent step towards this goal has been the production of a map of Mesoproterozoic and older basement geology for a large region of central Australia, from the eastern Yilgarn Craton of Western Australia across the Musgrave and southern Arunta Provinces to the Queensland border.
