Preliminary national-scale lead isotope maps of Australia

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.


Northern Australia Geochemical Survey: Data Release 2

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.


Source rock geochemistry of the McArthur Basin, Northern Australia

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.


Geochronology Compilation for Northern Australia: Version 2, 2018

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.


Identification of a new gold event at Tennant Creek expands search space for more discoveries

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.


AusAEM: Data release 1, NT and QLD

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
