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
Our first virtual seminar series has come to a close. After 15 weeks of seminars we will take a short break, but rest assured that we will be back shortly with a new round of speakers.
