Data & Publications
15 March 2019
New dataset presents preliminary national-scale maps of Australia derived from lead isotope data showing mineral occurrences, prospects and deposits. The maps will be updated as more data become available.
15 March 2019
New data release from the North Australian Geochemical Survey which sampled catchment outlet sediments at 780 sites in Tennant Creek and Mount Isa. The samples were analysed for over 50 chemical elements present in the soil. The report includes additional new analysis on the distribution of gold, platinum and palladium over the survey area.
20 February 2019
This study aims to improve our understanding of the petroleum resource potential of Northern Australia. This report characterises the organic richness, kerogen type and thermal maturity of source rocks in the Velkerri, Barney Creek, Wollogorang and McDermott formations of the McArthur Basin based on Rock-Eval pyrolysis data analysed at Geoscience Australia.
20 December 2018
This report presents a compilation of publicly-available U-Pb geochronology from Queensland (QLD), Northern Territory (NT), Western Australia (WA) and the most northerly parts of South Australia (SA) and New South Wales (NSW). It represents a step towards a comprehensive U-Pb geochronology compilation for all of Australia.
29 August 2018
New result widens the exploration 'search space' for gold into rock formations in Tennant Creek previously regarded as too young to host this style of mineralisation.
13 June 2018
New data is available from the world's largest airborne electromagnetic (AusAEM) survey, covering an area between the prospective resgion between Tennat Creek and Mount Isa.
Northern Australia Geochemical Survey: Data release 1 - Total (fine fraction) and MMI element contents
10 May 2018
An an extensive soil sampling survey has been undertaken over an area between Tennant Creek and Mount Isa. The surface soil samples were analysed for their metal content.
19 March 2018
The first release of Geoscience Australia's national time based solid geology mapping program focuses on Tennant Creek to Mount Isa area. The geological data comprises four layers: Mesozoic, Paleozoic, Neoproterozoic and Pre-Neoproterozoic.
16 March 2018
A seismic reflection survey was undertaken over the South Nicholson Basin region straddling the NT and QLD border. The project aquired five seismic lines, totalling 1100 line kilometres.
16 March 2018
The Australian Geological Provinces Database contains descriptions and spatial extents of the fundamental geological elements of the Australian continent and offshore surrounds. The data includes the new outline of the South Nicholson Basin.
20 October 2017
The gravity survey was carried out in July 2017 over the South Nicholson Basin, to determine the geological structure of the basin and to assist with identifying the resource potential of the area.
