Recently published in Nature’s Scientific Reports, EDRG researchers discovered that diamonds found in oceanic rocks and the so-called super-deep continental diamonds share a common origin of recycled organic carbon deep within the Earth’s mantle.
The Earth’s deepest diamonds are commonly made up of former living organisms that have effectively been recycled more than 400 kilometres below the surface.

Published in Nature journal Communications Earth & Environment, the EDRG team and collaborators report the world’s largest known plagiogranite complex in the Eastern Desert of Egypt. Data indicates that the complex was produced by extensive partial melting of the accreted oceanic lower crust (as a proto-continental crust) instead of the previously known mechanisms in mid-ocean ridge environments.

EDRG members recently returned from the first post- COVID-19 field trip. The trip to the Jack Hills, including visiting a site that contains some of the Earth's oldest zircons, was a great success with fantastic outcrops and exceptional wildflowers.
Two members from the Earth Dynamics Research Group recently spent a few days visiting the Pia Wadjarri Remote Community School in Murchison, WA.
The Earth Dynamics Research Group held their 2021 Annual Science Retreat in the idyllic Porongurup Range in south-west Western Australia.
The Faculty of Science and Engineering at Curtin University recently held their 2020 Excellence Awards, at which the Earth Dynamics Research Group was named the Research Team of the year.
The Geological Society of America has recently awarded its highest award for 2021, the Penrose Medal, to Prof. Ian Dalziel of the University of Texas at Austin and a distinguished member of IGCP 648.
Important upcoming events

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).
