Machine learning approaches elucidate hemispherical dichotomy in global geochemical record
Members of the EDRG have applied machine learning approaches to analyse large sets of elemental and isotopic data of mantle-derived oceanic igneous rocks and plume-related samples. The results indicate that a north-south hemispherical subdivision is less favourable than defining the dichotomy between the African and Pacific mantle domains, which can best be explained by tectonic supercycles over the past one billion years involving two supercontinents and two superoceans.
The work had been published in Nature Geoscience.

Anomalies in global mantle isotope values linked to the supercontinent-superocean cycle
Research undertaken by EDRG PhD student Piero de Sampaio has shown that trends in radiogenic isotope data of mid-ocean ridge and plume-induced basalts, particularly those of the African mantle domain, can be linked to geodynamic processes related to the supercontinent cycle.
The work, published in Nature's Communications earth & environment, is the first arising from Piero's PhD work. Congratulations Piero!

EDRG Fieldtrip to Pilbara region to study some of the oldest rocks in Australia
A team of Earth Dynamics Research Group scienctists travelled to the Pilbara region to sample some of Australia's oldest rocks in order to constrain the paleogeographic evolution of the Pilbara during the Paleoarchean (3.2 - 3.6 billion years ago).

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).
The article also includes a link to an activity sheet for students and teachers. For more information, teaching resources, and course and career guides, see www.futurumcareers.com.
