2022 | Perth, Western Australia

6IAS and Target 2020 postponed until 2022


The premier symposium dedicated to Precambrian geosciences

After much discussion and research, the 6ias Committee regrets to advise you that they have decided to postpone the 6th International Archean Symposium (6ias) and Target2020 (to be rebranded Target 2022) conferences until 2022. We note that the 2021 calendar year is now filled with conferences already booked and those transferred from 2020, and we continue to face ongoing uncertainty regarding the opening of international borders. As such, we have decided that hosting the symposium in 2022 will maximise the opportunity for participation for our international Archean community. We anticipate that the 6ias 2022 conference will be held sometime in the mid-year.

Important dates and deadlines for registration for the 6ias and Target 2022 will be announced next year via this webpage. Please subscribe to the 6ias newsletter for further announcements.

During the remainder of 2020 and into 2021, the 6ias and Geoconferences committees will endeavour to foster the global Archeal-Paleoproterzoic geoscience community through the development of a regular Webinar series.

For information regarding existing registrations for 6ias and Target 2020, please contact Jocylen Thomson, Geoconferences Secretariat, at info@6ias.org

Please keep safe and we look forward to welcoming you to Perth in 2022.

6th International Archean Symposium

2022 @ Perth, Western Australia

The 6th International Archean Symposium (6IAS) represents the premier international scientific gathering for geoscientists interested in the Early Earth. The program will reflect a decade’s worth of advances in our understanding of how the Early Earth evolved and aims to develop future directions for Precambrian geoscience for the decade to come. The symposium continues the series of highly successful IAS meetings presented every decade by Geoconferences (WA). We invite academic, government and industry geoscientists involved in Precambrian geoscience to attend the 6th International Archean Symposium, which will be held from 2022 at The University of Western Australia in Perth, Australia.

Link to abstract submission


The 6th International Archean Symposium aims to highlight some of the most significant contributions and greatest advances in research into Precambrian geoscience from the last ten years.

The 6ias Organising Committee has announced a diverse three-day technical program including high-level plenary sessions, panel discussion and poster sessions, reflecting the depth and breadth of current geoscientific knowledge. More than 400 researchers, industry practitioners and government geoscientists from around the world are expected at this event. Pre- and post-conference field trips explore some of Australia’s most impressive Precambrian geological sites in the Pilbara, Gawler and Yilgarn Cratons.

The technical program will include high-level plenary sessions and themed technical sessions, as well as panel discussions and poster sessions.

Pre-conference field trips

Pre-conference field trips are located in both Western Australia and South Australia. Take a tour through the exquisitely-exposed Pilbara Craton, exploring evolving Archean tectonic styles. Alternatively, examine the Paleoproterozoic reworking of an Archean craton in the southern Gawler Craton.

Target 2022


Target 2022 (formerly known as Target 2020), organized by Geoconferences (WA), will be held on 2022 in Perth, Western Australia following the 6th International Archean Symposium (6IAS). The meeting will showcase innovations developed to aid the discovery of new tier-one deposits and broaden the exploration space under cover. The meeting will cover all aspects of mineral exploration, providing a unique opportunity to workshop solutions to the mineral industry challenges that lie ahead.

Post-conference field trips

Post-conference field trips will explore the unique Archean and Precambrian geology of Western Australia. Individual trips will focus on the tectono-magmatic and metamorphic evolution of the northern Yilgarn Craton, mineralization in the eastern Goldfields of the Yilgarn Craton, as well as the Archean–Proterozoic boundary preserved in the Mount Bruce Supergroup.
