Deep mantle unveils a two-faced Earth
Research led by scientists in the Earth Dynamics Research Group, and published in Nature Geoscience, suggests that the Earth has two chemically distinct hemispheric ‘faces’ or domains.
Early whole mantle remixing suggests a start of global plate tectonics before three billion years ago
New work, published in the journal Scientific Reports, found that after the initial chemical stratification and formation of a hard shell in the first billion years of our planet’s history, there was a major chemical ‘stir-up’ some 3.2 billion years ago.

New article in Nature Geoscience!
A recently published Nature Geoscience article outlines the critical importance of water in the melting that occurs in subduction zones. This work, lead by Prof. Bill Collins, also discusses how this fluid-fluxed melting influences the mineralogical and geochemical signatures of the continental crust.
Prof. Zheng-Xiang Li recognised in 2019 Class of AGU Fellows
Each year AGU elects Fellows whose visionary leadership and scientific excellence have fundamentally advanced research in their respective fields. Professor Zheng-Xiang Li has been named in the list of 62 new AGU Fellows to be honored at the AGU Fall Meeting 2019 in San Francisco, California.
Congratulations Prof. Li!
IGCP 648 2019 Field Symposium – A Geologic Transect of Madagascar
The IGCP 648 2019 Field Symposium on the Precambrian evolution of Madagascar was well attended, with 31 geoscientists representing 11 countries. Read an entertaining account of the symposium written by Prof. Damian Nance.
Prof. Dietmar Müller awarded the Jaeger Medal
The Australian Academy of Science recently acknowledged the outstanding contributions of 20 of Australia’s leading scientists and future superstars. Prof. Müller was awarded the Jaeger Medal for lifelong achievement, which recognises research on the Earth or its oceans carried out in Australia or with a connection to Australian Earth science.
Decoding the Earth’s rhythms
A new IGCP 648 publication in Precambrian Research highlights how the supercontinents appear to have assembled and broken up through alternating processes of ‘introversion’ and ‘extroversion’. The process spans twice the period of the supercontinent cycle and involves either the survival or regeneration of superoceans and the subduction girdle.
