New research calibrates the clock for dating Earth evolution and mineral deposit formation
Researchers from the EDRG established a new framework for dating Earth's evolution such as the formation of continents and critical mineral deposits. The work, published in Earth Science Reviews, studied Australia’s abundant lead-zinc ore deposits along with a vast global database, and determined that 3.2 billion years ago was a critical point in Earth history.

A new Nature Geoscience, published by current and former EDRG members, explored a period in Earth's history when day length's were significantly shorter. They report an intiguing discovery that the day-length may have stalled during the 'boring billion' between 1 to 2 billion years ago.

The Australia-China Joint Research Centre for Tectonics and Earth Resources (ACTER) held a social lunch following the International Archean Symposium held in Fremantle, Western Australia. It was a pleasure to reinvigorate the partnerships and develop new connections.
The Special Symposium on Dynamic Evolution of Earth and its Environment, held during the Australian Earth Sciences Convention, was a great success. It was also a pleasure to catch up with the Australian Palaeomagnetic and Rock-magnetic community following the convention.
The Earth Dynamics Research Group held another enjoyable Annual Science Retreat in May 2023, at the wonderful Seashells Resort in Mandurah, Western Australia.
In April and May, EDRG members conducted a field trip to Scotland, Wales, Portugal and Spain with the aim to collect samples from oceanic rocks that belonged to two Palaeozoic oceans that separated the southern megacontinent Gondwana from Laurentia, the precursor to North America.
EDRG member Daniel Brennan was recently conferred his Doctor of Philosophy. His work set a very high standard for geoscience PhD work, and helped to make the team greater.
Congratulations Dr Brennan and all the best!

Community Feature Article
Prof. Li was recently featured in an article discussing the work that we do in the Earth Dynamics Research Group. The article was produced by Futurum, a magazine and online platform aimed at inspiring young people to follow a career in science, technology, engineering, and mathematics (STEM).
