6IAS
6th International Archean Symposium
25 – 27 July 2023 @ Perth, Western Australia
The 6th International Archean Symposium (6IAS) represented the premier international scientific gathering for geoscientists interested in the Early Earth. The program reflected 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). The event hosted academic, government and industry geoscientists involved in Precambrian geoscience to attend the 6th International Archean Symposium, and was held in 2023 in Perth, Australia.
The 6IAS Organising Committee welcomed attendees to the beautiful city of Perth in Western Australia to enjoy not only a rich scientific and social program, but also to visit classic geological sites and mineral deposits in Western Australia.
Themes
- Early Earth evolution: perspectives from the oldest minerals and rocks
- Emergence of atmosphere and life on early Earth and other terrestrial planets
- Development of Archean continental crust and lithosphere: including insights from numerical modelling, planetary geodynamics, and stages of Archean geodynamic evolution
- Role of Archean lithosphere in the evolution of younger terranes: including contribution of geophysics and geochemistry to understanding Archean terranes and their margins
- Archean terranes and craton margins in BRICS region (Brazil-Russia-India-China-South Africa)
- Archean to Proterozoic transition
- Mineral systems of Archean terranes and their margins
Field trips
