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.

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.
Dr Sergei Pisarevsky was recently awarded a Russian "megagrant" for the project "Orogenesis: Assembly and Growth of Continents and Supercontinents". The grant will lead to the creation of a new facility at the Institute of the Earth's Crust, Siberian Branch of the Russian Academy of Sciences.
PhD student Daniel Brennan was recently awarded the best student geologic map at the 2019 Geological Society of America's Annual meeting in Phoenix, Arizona.
Well done Dan!
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!
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.
Important upcoming events
Join us this Thursday 9th July at 15:00 GMT for our next Zoom seminar with Anna Gülcher, PhD Candidate at ETH Zürich Institute of Geophysics, Switzerland presenting: Towards a recipe of the deep Earth: chemical and rheological heterogeneity in the lower mantle.
The seminar will be hosted on Zoom. Additional information is available here.

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).
